    Hi Everyone,

    Currently I m doing a project using 18F4550,my project has to accept user input via RS232 and send it to control a DAC configured in SPI.

    The following are accomplished,

    1) DAC is working fine only when SDO is enabled.

    2) UART is working fine.

    my problem is when I configure ie multiplex both RX and SDO (SPI) in the same project only the RS 232 is working and the DAC is not working.

    Pls help me.
