"Good" documentation for use of UART FIFO?
Is there any decent document or examples around that shows how to use the UART FIFO?
I note many discussions on UARTs and there seems to be plenty of confusion.
At present, I set up the UART for single byte RX interrupt and have a circular buffer being fed by the interrupt and the mainline code dequing and parsing the received data, looking for valid packets.
It seems to me the FIFO should be able to replace my circular buffer.
There seem to be little documentation regarding inetrrupt driven UART, Use of the FIFO and what sort of error checking should be done.
