The measurement timer will then start again once the queue is empty. This works fine as long as the FIFO still contain packages when an ACK is received. If not, I run into the problem described in my question. (2) The device will likely need to be reset in order to function again. I think I will implement a "communication reset" function that clears all TX and RX buffers after one second of no activity on the UART. This should be easy to implement as I have done that before. | |

| Oct 27, 2015 at 22:03 | comment | added | Jon | A few questions: (1) what happens if the PC doesn't poll your device and the fifo overflows? (2) If the PC doesn't send an ACK (maybe the transmission gets lost) what does your device do? | |
