110 Baud Serial Communications - Possible?

[jamie_s]

Im looking at using PIC's for a serial interface / converter for some legacy equipment, which requires a baud rate of 110bps.

Is there any way a pic can go down to 110bps for serial input and output?
All i have found so far is some info on 300.

You should be able to do this easily.

The method depends on whether or not you are using software (SERIN2/SEROUT2) or hardware (HSERIN/HSEROUT) UARTS.

For SERIN2/SEROUT2 you can use the formula given on page 129 of the PBP manual -

MODE = (1000000/baud) - 20


For HSERIN/HSEROUT check the datasheet for your processor. You will have to directly set BRGH and SPBRG according to your oscillator frequency.
