PostPosted: Sun Feb 12, 2006 5:45 am     Reply with quote
how can I check in rs232 software (non UART) the parameter "ERROR"?

Thanks

The compiler generates a variable, called 'RS232_ERRORS'. In software mode, only two bits of this actually 'means' anything. Bit 7, is the 9th data bit for 9 bit I/O, and bit 6, reflects if the bus was idle, when using the 'float high mode, and a transmission was attempted. No other 'error' conditions are generated by the soft UART (no parity or framing errors).

Best Wishes
