|

*
|

* Main.c also creates a task called "Check". This only executes every three
|
||||
* seconds but has the highest priority so is guaranteed to get processor time.
|
||||
* Its main function is to check that all the other tasks are still operational.
|
||||
* Each task (other than the "flash" tasks) maintains a unique count that is
|
||||
* incremented each time the task successfully completes its function. Should
|
||||
* any error occur within such a task the count is permanently halted. The
|
||||
* check task inspects the count of each task to ensure it has changed since
|
||||
* the last time the check task executed. If all the count variables have
|
||||
* changed all the tasks are still executing error free, and the check task
|
||||
* toggles the onboard LED. Should any task contain an error at any time
|
||||
* the LED toggle rate will change from 3 seconds to 500ms.
|
||||
*
|
||||
* To check the operation of the memory allocator the check task also
|
||||
* dynamically creates a task before delaying, and deletes it again when it
|
||||
* wakes. If memory cannot be allocated for the new task the call to xTaskCreate
|
||||
* will fail and an error is signalled. The dynamically created task itself
|
||||
* allocates and frees memory just to give the allocator a bit more exercise.

/*
|
||||
* This file contains a demo created to execute on the Rowley Associates
|
||||
* LPC2138 CrossFire development board.
|
||||
*
|
||||
* main() creates all the demo application tasks, then starts the scheduler.
|
||||
* The WEB documentation provides more details of the standard demo application
|
||||
* tasks.
|
||||
*
|
||||
* Main.c also creates a task called "Check". This only executes every few
|
||||
* seconds but has a high priority so is guaranteed to get processor time.
|
||||
* Its function is to check that all the other tasks are still operational.
|
||||
* Each standard demo task maintains a unique count that is incremented each
|
||||
* time the task successfully completes its function. Should any error occur
|
||||
* within such a task the count is permanently halted. The check task inspects
|
||||
* the count of each task to ensure it has changed since the last time the
|
||||
* check task executed. If all the count variables have changed all the tasks
|
||||
* are still executing error free, and the check task writes "PASS" to the
|
||||
* CrossStudio terminal IO window. Should any task contain an error at any time
|
||||
* the error is latched and "FAIL" written to the terminal IO window.
|
||||
*
|
||||
* Finally, main() sets up an interrupt service routine and task to handle
|
||||
* pushes of the button that is built into the CrossFire board. When the button
|
||||
* is pushed the ISR wakes the button task - which generates a table of task
|
||||
* status information which is also displayed on the terminal IO window.
|
||||
*
|
||||
* A print task is defined to ensure exclusive and consistent access to the
|
||||
* terminal IO. This is the only task that is allowed to access the terminal.
|
||||
* The check and button task therefore do not access the terminal directly but
|
||||
* instead pass a pointer to the message they wish to display to the print task.

* Creates all the demo application tasks, then starts the scheduler. The WEB

* documentation provides more details of the standard demo application tasks.
|
||||
* In addition to the standard demo tasks, the following tasks and tests are
|
||||
* defined and/or created within this file:
|
||||
*
|
||||
* "LCD" task - the LCD task is a 'gatekeeper' task. It is the only task that
|
||||
* is permitted to access the display directly. Other tasks wishing to write a
|
||||
* message to the LCD send the message on a queue to the LCD task instead of
|
||||
* accessing the LCD themselves. The LCD task just blocks on the queue waiting
|
||||
* for messages - waking and displaying the messages as they arrive.
|
||||
*
|
||||
* "Check" hook - This only executes every five seconds from the tick hook.
|
||||
* Its main function is to check that all the standard demo tasks are still
|
||||
* operational. Should any unexpected behaviour within a demo task be discovered
|
||||
* the tick hook will write an error to the LCD (via the LCD task). If all the
|
||||
* demo tasks are executing with their expected behaviour then the check task
|
||||
* writes PASS to the LCD (again via the LCD task), as described above.
|
||||
*
|
||||
* "uIP" task - This is the task that handles the uIP stack. All TCP/IP
|
||||
* processing is performed in this task.

* Creates all the demo application tasks, then starts the scheduler. The WEB

|
||||
*
|
||||
* In addition to the standard demo tasks there are two tasks defined within
|
||||
* this file:
|
||||
*
|
||||
* 1 - The check task
|
||||
* The 'check' task is responsible for ensuring that all the standard demo
|
||||
* tasks are executing as expected. It only executes every three seconds, but
|
||||
* has the highest priority within the system so is guaranteed to get execution
|
||||
* time. Any errors discovered by the check task are latched until the
|
||||
* processor is reset. At the end of each cycle the check task sends either
|
||||
* a pass or fail message to the 'print' task for display on the LCD.
|
||||
*
|
||||
* 2 - The print task
|
||||
* The print task is the LCD 'gatekeeper'. That is, it is the only task that
|
||||
* should access the LCD directly so is always guaranteed exclusive (and
|
||||
* therefore consistent) access. The print task simply blocks on a queue
|
||||
* to wait for messages from other tasks wishing to display text on the LCD.
|
||||
* When a message arrives it displays its contents on the LCD then blocks to
|
||||
* wait again.

* Creates all the demo application tasks, then starts the scheduler. The WEB
|
||||
* documentation provides more details of the demo application tasks.
|
||||
*
|
||||
* In addition to the standard demo tasks there are two tasks defined within
|
||||
* this file:
|
||||
*
|
||||
* 1 - The check task
|
||||
* The 'check' task is responsible for ensuring that all the standard demo
|
||||
* tasks are executing as expected. It only executes every three seconds, but
|
||||
* has the highest priority within the system so is guaranteed to get execution
|
||||
* time. Any errors discovered by the check task are latched until the
|
||||
* processor is reset. At the end of each cycle the check task sends either
|
||||
* a pass or fail message to the 'print' task for display on the LCD.
|
||||
*
|
||||
* 2 - The print task
|
||||
* The print task is the LCD 'gatekeeper'. That is, it is the only task that
|
||||
* should access the LCD directly so is always guaranteed exclusive (and
|
||||
* therefore consistent) access. The print task simply blocks on a queue
|
||||
* to wait for messages from other tasks wishing to display text on the LCD.
|
||||
* When a message arrives it displays its contents on the LCD then blocks to
|
||||
* wait again.

* displayed on the top row of the LCD.
|

*
|
||||
* The Check task only executes every three seconds but has the highest
|

* priority so is guaranteed to get processor time. Its main function is to

* check that all the other tasks are still operational. Most tasks maintain

||||
* a unique count that is incremented each time the task successfully completes
|
||||
* a cycle of its function. Should any error occur within such a task the
|

* count is permanently halted. The check task sets a bit in an error status
|
||||
* flag should it find any counter variable at a value that indicates an
|
||||
* error has occurred. The error flag value is converted to a string and sent
|
||||
* to the LCD task for display on the bottom row on the LCD.

* \brief FreeRTOS Real Time Kernel example.

* Creates all the demo application tasks, then starts the scheduler. The WEB
|

* documentation provides more details of the demo application tasks.
|
||||
*
|
||||
* Main. c also creates a task called "Check". This only executes every three
|
||||
* seconds but has the highest priority so is guaranteed to get processor time.
|
||||
* Its main function is to check that all the other tasks are still operational.
|
||||
* Each task that does not flash an LED maintains a unique count that is
|
||||
* incremented each time the task successfully completes its function. Should
|
||||
* any error occur within such a task the count is permanently halted. The
|
||||
* check task inspects the count of each task to ensure it has changed since
|
||||
* the last time the check task executed. If all the count variables have
|
||||
* changed all the tasks are still executing error free, and the check task
|
||||
* toggles an LED. Should any task contain an error at any time the LED toggle
|
||||
* will stop.
|
||||
*
|
||||
* The LED flash and communications test tasks do not maintain a count.

Changes from V1.2.3
|

is being used. Previously they were only used with the preemptive
|

scheduler.
|

Changes from V1.2.5
|

8MHz clock (according to the manual).
|

Changes from V2.0.0
|

portTickType rather than unsigned long.
|
||||
|
||||
Changes from V2.2.0
|

Changes from V1.2.0
|
||||
|
||||
+ Changed the baud rate for the serial test from 19200 to 57600.
|
||||
|
||||
Changes from V1.2.3
|
||||
|
||||
+ The integer and comtest tasks are now used when the cooperative scheduler
|
||||
is being used. Previously they were only used with the preemptive
|
||||
scheduler.
|
||||
|
||||
Changes from V1.2.5
|
||||
|
||||
+ Set the baud rate to 38400. This has a smaller error percentage with an
|
||||
8MHz clock (according to the manual).
|
||||
|
||||
Changes from V2.0.0
|
||||
|
||||
+ Delay periods are now specified using variables and constants of
|
||||
portTickType rather than unsigned long.
|
||||
|
||||
Changes from V2.6.1
|
||||
|
||||
+ The IAR and WinAVR AVR ports are now maintained separately.
|
||||
|
||||
Changes from V4.0.5
|
||||
|
||||
+ Modified to demonstrate the use of co-routines.

+ The function xPortInitMinimal() has been renamed to

xSerialPortInitMinimal() and the function xPortInit() has been renamed

to xSerialPortInit().
|

|

Changes from V2.0.0
|

+ Delay periods are now specified using variables and constants of

portTickType rather than unsigned long.
|

+ xQueueReceiveFromISR() used in place of xQueueReceive() within the ISR.
|

|

Changes from V2.6.0
|

|
||||
+ Replaced the inb() and outb() functions with direct memory
|

access. This allows the port to be built with the 20050414 build of

* one queue, and one timer. It also demonstrates how Cortex-M3 interrupts can
|
||||
* interact with FreeRTOS tasks/timers.
|
||||
*
|
||||
* This simple demo project runs on the SmartFusion A2F-EVAL-KIT evaluation
|
||||
* board, which is populated with an A2F200M3F SmartFusion mixed signal FPGA.
|
||||
* The A2F200M3F incorporates a Cortex-M3 microcontroller.
|
||||
*
|
||||
* The idle hook function:
|
||||
* The idle hook function demonstrates how to query the amount of FreeRTOS heap
|
||||
* space that is remaining (see vApplicationIdleHook() defined in this file).
|
||||
*
|
||||
* The main() Function:
|
||||
* main() creates one software timer, one queue, and two tasks. It then starts
|
||||
* the scheduler.
|
||||
*
|
||||
* The Queue Send Task:
|
||||
* The queue send task is implemented by the prvQueueSendTask() function in
|
||||
* this file. prvQueueSendTask() sits in a loop that causes it to repeatedly
|
||||
* block for 200 milliseconds, before sending the value 100 to the queue that
|
||||
* was created within main(). Once the value is sent, the task loops back
|
||||
* around to block for another 200 milliseconds.
|
||||
*
|
||||
* The Queue Receive Task:
|
||||
* The queue receive task is implemented by the prvQueueReceiveTask() function
|
||||
* in this file. prvQueueReceiveTask() sits in a loop that causes it to
|
||||
* repeatedly attempt to read data from the queue that was created within
|
||||
* main(). When data is received, the task checks the value of the data, and
|
||||
* if the value equals the expected 100, toggles the green LED. The 'block
|
||||
* time' parameter passed to the queue receive function specifies that the task
|
||||
* should be held in the Blocked state indefinitely to wait for data to be
|
||||
* available on the queue. The queue receive task will only leave the Blocked
|
||||
* state when the queue send task writes to the queue. As the queue send task
|
||||
* writes to the queue every 200 milliseconds, the queue receive task leaves
|
||||
* the Blocked state every 200 milliseconds, and therefore toggles the LED
|
||||
* every 200 milliseconds.
|
||||
*
|
||||
* The LED Software Timer and the Button Interrupt:
|
||||
* The user button SW1 is configured to generate an interrupt each time it is
|
||||
* pressed. The interrupt service routine switches an LED on, and resets the
|
||||
* LED software timer. The LED timer has a 5000 millisecond (5 second) period,
|
||||
* and uses a callback function that is defined to just turn the LED off again.
|
||||
* Therefore, pressing the user button will turn the LED on, and the LED will
|
||||
* remain on until a full five seconds pass without the button being pressed.

||||
* main-blinky.c is included when the "Blinky" build configuration is used.
|
||||
* main-full.c is included when the "Full" build configuration is used.
|
||||
*
|
||||
* main-full.c (this file) defines a comprehensive demo that creates many
|
||||
* tasks, queues, semaphores and timers. It also demonstrates how Cortex-M3
|
||||
* interrupts can interact with FreeRTOS tasks/timers, and implements a simple
|
||||
* and small interactive web server.
|
||||
*
|
||||
* This project runs on the SmartFusion A2F-EVAL-KIT evaluation board, which
|
||||
* is populated with an A2F200M3F SmartFusion mixed signal FPGA. The A2F200M3F
|
||||
* incorporates a Cortex-M3 microcontroller.
|
||||
*
|
||||
* The main() Function:
|
||||
* main() creates two demo specific software timers, one demo specific queue,
|
||||
* and three demo specific tasks. It then creates a whole host of 'standard
|
||||
* demo' tasks/queues/semaphores, before starting the scheduler. The demo
|
||||
* specific tasks and timers are described in the comments here. The standard
|
||||
* demo tasks are described on the FreeRTOS.org web site.
|
||||
*
|
||||
* The standard demo tasks provide no specific functionality. They are
|
||||
* included to both test the FreeRTOS port, and provide examples of how the
|
||||
* various FreeRTOS API functions can be used.
|
||||
*
|
||||
* The Demo Specific Queue Send Task:
|
||||
* The queue send task is implemented by the prvQueueSendTask() function in
|
||||
* this file. prvQueueSendTask() sits in a loop that causes it to repeatedly
|
||||
* block for 200 milliseconds, before sending the value 100 to the queue that
|
||||
* was created within main(). Once the value is sent, the task loops back
|
||||
* around to block for another 200 milliseconds.
|
||||
*
|
||||
* The Demo Specific Queue Receive Task:
|
||||
* The queue receive task is implemented by the prvQueueReceiveTask() function
|
||||
* in this file. prvQueueReceiveTask() sits in a loop that causes it to
|
||||
* repeatedly attempt to read data from the queue that was created within
|
||||
* main(). When data is received, the task checks the value of the data, and
|
||||
* if the value equals the expected 100, toggles the green LED. The 'block
|
||||
* time' parameter passed to the queue receive function specifies that the task
|
||||
* should be held in the Blocked state indefinitely to wait for data to be
|
||||
* available on the queue. The queue receive task will only leave the Blocked
|
||||
* state when the queue send task writes to the queue. As the queue send task
|
||||
* writes to the queue every 200 milliseconds, the queue receive task leaves
|
||||
* the Blocked state every 200 milliseconds, and therefore toggles the LED
|
||||
* every 200 milliseconds.
|
||||
*
|
||||
* The Demo Specific OLED Task:
|
||||
* The OLED task is a very simple task that just scrolls a message across the
|
||||
* OLED. Ideally this would be done in a timer, but the OLED driver accesses
|
||||
* the I2C which is time consuming.
|
||||
*
|
||||
* The Demo Specific LED Software Timer and the Button Interrupt:
|
||||
* The user button SW1 is configured to generate an interrupt each time it is
|
||||
* pressed. The interrupt service routine switches an LED on, and resets the
|
||||
* LED software timer. The LED timer has a 5000 millisecond (5 second) period,
|
||||
* and uses a callback function that is defined to just turn the LED off again.
|
||||
* Therefore, pressing the user button will turn the LED on, and the LED will
|
||||
* remain on until a full five seconds pass without the button being pressed.
|
||||
*
|
||||
* The Demo Specific "Check" Callback Function:
|
||||
* This is called each time the 'check' timer expires. The check timer
|
||||
* callback function inspects all the standard demo tasks to see if they are
|
||||
* all executing as expected. The check timer is initially configured to
|
||||
* expire every three seconds, but will shorted this to every 500ms if an error
|
||||
* is ever discovered. The check timer callback toggles the LED defined by
|
||||
* the mainCHECK_LED definition each time it executes. Therefore, if LED
|
||||
* mainCHECK_LED is toggling every three seconds, then no error have been found.
|
||||
* If LED mainCHECK_LED is toggling every 500ms, then at least one errors has
|
||||
* been found. The task in which the error was discovered is displayed at the
|
||||
* bottom of the "task stats" page that is served by the embedded web server.
|
||||
*
|
||||
* The Demo Specific Idle Hook Function:
|
||||
* The idle hook function demonstrates how to query the amount of FreeRTOS heap
|
||||
* space that is remaining (see vApplicationIdleHook() defined in this file).
|
||||
*
|
||||
* The Web Server Task:
|
||||
* The IP address used by the SmartFusion target is configured by the
|
||||
* definitions configIP_ADDR0 to configIP_ADDR3, which are located in the
|
||||
* FreeRTOSConfig.h header file. See the documentation page for this example
|
||||
* on the http://www.FreeRTOS.org web site for further connection information.

* The queue receive task is implemented by the prvQueueReceiveTask() function

* in this file. prvQueueReceiveTask() sits in a loop that causes it to

* repeatedly attempt to read data from the queue that was created within

||||
* available on the queue. The queue receive task will only leave the Blocked
|
||||
* state when the queue send task writes to the queue. As the queue send task
|
||||
* writes to the queue every 200 milliseconds, the queue receive task leaves
|
||||
* the Blocked state every 200 milliseconds, and therefore toggles the LED
|
||||
* every 200 milliseconds.
|
||||
*
|
||||
* The LED Software Timer and the Button Interrupt:
|
||||
* The user button SW1 is configured to generate an interrupt each time it is
|
||||
* pressed. The interrupt service routine switches an LED on, and resets the
|
||||
* LED software timer. The LED timer has a 5000 millisecond (5 second) period,
|
||||
* and uses a callback function that is defined to just turn the LED off again.
|
||||
* Therefore, pressing the user button will turn the LED on, and the LED will
|
||||
* remain on until a full five seconds pass without the button being pressed.

/*
|
||||
* main-blinky.c is included when the "Blinky" build configuration is used.
|
||||
* main-full.c is included when the "Full" build configuration is used.
|
||||
*
|
||||
* main-full.c (this file) defines a comprehensive demo that creates many
|
||||
* tasks, queues, semaphores and timers. It also demonstrates how Cortex-M3
|
||||
* interrupts can interact with FreeRTOS tasks/timers, and implements a simple
|
||||
* and small interactive web server.
|
||||
*
|
||||
* This project runs on the SmartFusion A2F-EVAL-KIT evaluation board, which
|
||||
* is populated with an A2F200M3F SmartFusion mixed signal FPGA. The A2F200M3F
|
||||
* incorporates a Cortex-M3 microcontroller.
|
||||
*
|
||||
* The main() Function:
|
||||
* main() creates two demo specific software timers, one demo specific queue,
|
||||
* and three demo specific tasks. It then creates a whole host of 'standard
|
||||
* demo' tasks/queues/semaphores, before starting the scheduler. The demo
|
||||
* specific tasks and timers are described in the comments here. The standard
|
||||
* demo tasks are described on the FreeRTOS.org web site.
|
||||
*
|
||||
* The standard demo tasks provide no specific functionality. They are
|
||||
* included to both test the FreeRTOS port, and provide examples of how the
|
||||
* various FreeRTOS API functions can be used.
|
||||
*
|
||||
* The Demo Specific Queue Send Task:
|
||||
* The queue send task is implemented by the prvQueueSendTask() function in
|
||||
* this file. prvQueueSendTask() sits in a loop that causes it to repeatedly
|
||||
* block for 200 milliseconds, before sending the value 100 to the queue that
|
||||
* was created within main(). Once the value is sent, the task loops back
|
||||
* around to block for another 200 milliseconds.
|
||||
*
|
||||
* The Demo Specific Queue Receive Task:
|
||||
* The queue receive task is implemented by the prvQueueReceiveTask() function
|
||||
* in this file. prvQueueReceiveTask() sits in a loop that causes it to
|
||||
* repeatedly attempt to read data from the queue that was created within
|
||||
* main(). When data is received, the task checks the value of the data, and
|
||||
* if the value equals the expected 100, toggles the green LED. The 'block
|
||||
* time' parameter passed to the queue receive function specifies that the task
|
||||
* should be held in the Blocked state indefinitely to wait for data to be
|
||||
* available on the queue. The queue receive task will only leave the Blocked
|
||||
* state when the queue send task writes to the queue. As the queue send task
|
||||
* writes to the queue every 200 milliseconds, the queue receive task leaves
|
||||
* the Blocked state every 200 milliseconds, and therefore toggles the LED
|
||||
* every 200 milliseconds.
|
||||
*
|
||||
* The Demo Specific OLED Task:
|
||||
* The OLED task is a very simple task that just scrolls a message across the
|
||||
* OLED. Ideally this would be done in a timer, but the OLED driver accesses
|
||||
* the I2C which is time consuming.
|
||||
*
|
||||
* The Demo Specific LED Software Timer and the Button Interrupt:
|
||||
* The user button SW1 is configured to generate an interrupt each time it is
|
||||
* pressed. The interrupt service routine switches an LED on, and resets the
|
||||
* LED software timer. The LED timer has a 5000 millisecond (5 second) period,
|
||||
* and uses a callback function that is defined to just turn the LED off again.
|
||||
* Therefore, pressing the user button will turn the LED on, and the LED will
|
||||
* remain on until a full five seconds pass without the button being pressed.
|
||||
*
|
||||
* The Demo Specific "Check" Callback Function:
|
||||
* This is called each time the 'check' timer expires. The check timer
|
||||
* callback function inspects all the standard demo tasks to see if they are
|
||||
* all executing as expected. The check timer is initially configured to
|
||||
* expire every three seconds, but will shorted this to every 500ms if an error
|
||||
* is ever discovered. The check timer callback toggles the LED defined by
|
||||
* the mainCHECK_LED definition each time it executes. Therefore, if LED
|
||||
* mainCHECK_LED is toggling every three seconds, then no error have been found.
|
||||
* If LED mainCHECK_LED is toggling every 500ms, then at least one errors has
|
||||
* been found. The task in which the error was discovered is displayed at the
|
||||
* bottom of the "task stats" page that is served by the embedded web server.
|
||||
*
|
||||
* The Demo Specific Idle Hook Function:
|
||||
* The idle hook function demonstrates how to query the amount of FreeRTOS heap
|
||||
* space that is remaining (see vApplicationIdleHook() defined in this file).
|
||||
*
|
||||
* The Web Server Task:
|
||||
* The IP address used by the SmartFusion target is configured by the
|
||||
* definitions configIP_ADDR0 to configIP_ADDR3, which are located in the
|
||||
* FreeRTOSConfig.h header file. See the documentation page for this example
|
||||
* on the http://www.FreeRTOS.org web site for further connection information.
