Hello all, I want to use the winbond w78c438 port8 as the serial port, because i want to use origianl serial. but mon51 does not provide this function,Please anybody help?
Port 8 does not have a serial UART function. So you cannot use this I/O port for Monitor communication. However, you may add an external UART to your design. This can be adapted in the file INSTALL.A51 that is part of the Monitor 51 software.
another possibility is a "soft" UART Have fun, Erik
