> ulTutoralRunTime in tasks.c has to be defined as volatile
This may be a Atollic TrueStudio specific requirement for updating their GUI FreeRTOS Task List view.
In general, no changes are required and the code works out-of-the-box when using the FreeRTOS supplied vTaskGetRunTimeStats function.
Set up an up-counting timer running at a frequency considerably higher than the FreeRTOS tick, say TIM2 at 1 MHz.
Activate in FreeRTOSConfig.h:
#define configGENERATE_RUN_TIME_STATS 1
#define configUSE_TRACE_FACILITY 1
#define configUSE_STATS_FORMATTING_FUNCTIONS 1
Override the _weak defaults by implementing:
void configureTimerForRunTimeStats(void)
{
HAL_TIM_Base_Start(&htim2);
}
unsigned long getRunTimeCounterValue(void)
{
return __HAL_TIM_GET_COUNTER(&htim2);
}
And now you can periodically read-out the statistics in a tasks by:
char pcWriteBuffer[256];
vTaskGetRunTimeStats(pcWriteBuffer);
and send the results to an UART or other interface. You get output like
...
defaultTask 24120810 8%
IDLE 270603162 91%
Tmr Svc 58 <1%
Btw: There is no need to setup an additional timer interrupt as suggested in that tutorial. That creates only overhead...
