ported the PIC24F demo program to the “PIC24F Starter Kit” board (distribution demo is for “Explorer 16” board),
added Microchip USB stack and simulated serial port RX/TX to PC (displaying text on OLED).
So far, all AOK. And I will post the demo when I fix up a couple loose ends ! However… In my real application, I have an ISR using a binary semaphore to awaken a task.
I expected to code:
xSemaphoreGiveFromISR(channelDataReadySemaphore,&xHigherPriorityTaskAwoken); // unblock above channel data task
if(xHigherPriorityTaskAwoken==pdTRUE) { vPortYieldFromISR(); }
Unfortunately I can’t find any of vPortYieldFromISR, portSWITCH_CONTEXT, or portEND_SWITCHING_ISR in this port of FreeRTOS.
Sorry if I’m being dense, but how do I ensure that FreeRTOS will return to the awakened high-priority task from the ISR in this PIC24F port ?
Thanks in advance,Best Regards, Dave
