I have to develop a RS485 Master. So I have checked the Uart_Rs485Master Projekt on LPCware. This was good to start, the only messy thing is: When I have to send an address byte, I have to stick the parity on this byte and have to wait until the TX Shift Register (UnTSR) is empty. This was done in a while loop polling the LSR->TEMT flag.
Instead polling is there a chance to get an interrupt after the adress-byte was send?
