#84667 - MODBUS on UART (parity & stop bits?) |
Hi all,
I'm implementing MODBUS RTU 9600 bauds on a 89c668. I plan to user a timer to process the end of frame by reloading a timer each time a char is incoming. My problem is on the UART configuration. MODBUS requires to set the parity bit and to use 2 STOP bits. I havn't found in datasheets how to configure the 8051 UART do to this ? Is it possible to configure parity and stop bits on the hardware UART ? Otherwise shall I do a software UART to access MODBUS ? And suggestions on the MODBUS implementation would be appreciated (flowcharts, codes, ...) Regards Stephane |
