The bytes aren't on the right place, like some framing problem.XMEGA USART interrupt driven driver example source. And at attempt 6 it does result a in a string with the expected length, the (software) buffer seems corrupted some way. So lets say that the first 5 requests result in an error string which is shorter or longer than the expected length. The problem I have is that the ISR I use works fine when you're dealing with static and known string lengths.īut in this case the strings I'm receiving could have different lengths at any time. I'm repeating the command until I receive a usable answer. I'm requesting certain information by sending commands to the device.
I'm communicating with an other device over UART.
