#108070 - 8051 UART 'break' detection |
Does anybody know if the 8051(2) UART can be used to detect a break signal on the RXD line. I am testing it with a VB program and without the break I recieve the correct command with a break I get rubbish. It looks like the break is causing a framing error.
I have been asked to get the unit I am working on to receive a command from a controller which always sends a break at the start of each command. The controller protocol cannot be changed. Thanks... |
