I am using an MSP430f5438 with version 5.4 of FreeRTOS.
I am having a funny problem that I can t figure out.
Basically, when I set configTICK_RATE_HZ to different values, the LED blinks faster or slower; it should stay the same rate. It blinks slower the higher i set configTICK_RATE_HZ, and faster when I set TICK_RATE lower.
vTaskDelayUntil( &xLastFlashTime, xFlashRate ); is such that the LED should only blink once a second no matter what the configTICK_RATE_HZ is. I stepped through and checked the xFlashRate to make sure. Its always = to the configTICK_RATE_HZ. Code:
xFlashRate = ledFLASH_RATE_BASE;//my flash base rate is 1000ms
xFlashRate /= portTICK_RATE_MS; //so xFlashrate = whatever configTICK_RATE_HZ equals
/* We need to initialise xLastFlashTime prior to the first call to vTaskDelayUntil().*/
xLastFlashTime = xTaskGetTickCount();
for(;;) {
vTaskDelayUntil( &xLastFlashTime, xFlashRate ); vParTestToggleLED( uxLED );
flashled();//this should happen every 1 second.
}
The led blink with a period greater than 1 second when i set the configtick_rate_hz to 1000 and the led blinks with a period far less than 1s when i set the tick rate to anything less than ~200
configTICK_RATE_HZ should not affect the LED blinktime.
I realize more info is needed and will readily supply whatever code snippets are needed to help.
