We are working and sharing code alongside another company which is using the IAR IDE. We are providing functions for the other company to use by providing an .elf file. This .elf file contains functions they are going to use and it is generated in Ride7. We've also given them absolute addresses of our functions so they can call our functions from our .elf file inside their code. In their code, they are using FreeRTOS and a semaphore which will be used as a flag to symbolize that an AtoD conversion has been completed. Because we handle the AtoD conversion in one of our functions, it is up to us to release the semaphore at the end of the conversion. However, the semaphore is property of their OS. Is it possible to access and release their semaphore from inside of our code? I know I can release the semaphore using the following command:
------------------------------------------------------------------------------------------
// DMA ISR triggered after all ADC done
void DMAChannel1_IRQHandler(void){

portBASE_TYPE xHigherPriorityTaskWoken = pdFALSE;
if(DMA_GetITStatus(DMA1_IT_TC1) != RESET)
{
xSemaphoreGiveFromISR(xADC1Semaphore,&xHigherPriorityTaskWoken); // DMA ADC task completion flag to second task...
}
portEND_SWITCHING_ISR(xHigherPriorityTaskWoken);
}
-------------------------------------------------------------------------------------------
which initiates the following in their code:
-------------------------------------------------------------------------------------------
// This task is run next after xADC1Semaphore is given from DMA ISR
void prvADC2_DsrTask( void *pvParameters )
{

( void ) pvParameters;

for( ;; )
{
xSemaphoreTake(xADC1Semaphore, portMAX_DELAY);
// Add Post ADC collection process here...
}
}
----------------------------------------------------------------------------------------------

So how do we access their semaphore?

Thanks,
