    Default Hserin baudrate select

    Hi

    I would like to select between 2 Hserout baudrate's at start up
    by checking an input pin
    It is not possible to use "Define Hserbaud xxxx" twice or in an if/then loop

    Is it possible to select different baudrates after power-up ?

    Thanks

    Hi Walter,

    You can't change DEFINEs in mid-stream.

    But you can change the SPBRG register anytime you want.
    Although it's best to turn the module off before doing so.

    With RCSTA.
    Code:
    RCSTA = 0
SPBRG = NewBaudRate
RCSTA = $90
