K82 : I2C_RTOS_Transfer() timeout

Hello !

 

I'm using I2C master API for FreeRTOS and would like to estimate max timeout in case if I2C transaction can't be completed.

 

In API I2C_RTOS_Transfer() I can see infinite waiting of semaphore:

/* Wait for transfer to finish */
xSemaphoreTake(handle->semaphore, portMAX_DELAY);

 

What timeout mechanisms is exists inside I2C hardware what can garantie if I2C interrupt in controller is happens in any case for unblock waiting if semaphore in reasonable time ?

 

Regards,

Eugene
