Hi!

I'm quite new to the Atmel world though I have read tons of information on the subject. My project involves having to check for a break Signal on the RX line that is minimum of 14 bits long and likewise be able to write it on the TX line. I know that this is not UART conform but the bus I am about to try to implement uses this signal to tell the nodes that a data packet is about to be sent.

The RX line is aditionally connected to the ADC because it is planned to use it for a phyiscal logging of the voltages.

My first thought would be to check for a small piece of code that implements a software UART behind the hardware UART, so the HW UART just buffers and forwards the bits and the interpretation will be handled via SW.


My questions:

Does it make any sense to proceed like that or would it be better to use the ADC to recieve and some IO to send the break signal?

If my train of thought is widely correct: Is there some small usable piece of software that might be directly used with the SAM7SE UART?

thanks for any help!
