#define mainBLOCK_Q_PRIORITY   ( tskIDLE_PRIORITY + 3 )

Referenced by main().

#define mainCHECK_PERIOD   ( ( portTickType ) 3000 / portTICK_RATE_MS )

The period between executions of the check task.

Referenced by vErrorChecks().

#define mainCHECK_TASK_LED   ( 6 )

LED that is toggled by the check task.

The check task periodically checks that all the other tasks are operating without error. If no errors are found the LED is toggled. If an error is found at any time the LED toggles faster.

#define mainCHECK_TASK_PRIORITY   ( tskIDLE_PRIORITY + 4 )

#define mainCOM_TEST_BAUD_RATE   ( ( unsigned portLONG ) 57600 )

Baud rate used by the serial port tasks.

Referenced by main().

#define mainCOM_TEST_LED   ( 3 )

LED used by the serial port tasks.

This is toggled on each character Tx, and mainCOM_TEST_LED + 1 is toggled on each character Rx.
