I have posted about a low priced encoder for a 3D digitizer.The manufacture shows one method for using a PIC and a Serial Synchronous Interface (SSI) to RS232 convertor.
However the PICPRO compilier doesn't have built in floating point number types.There are code workarounds but I would rather not deal with it.
Could someone recommend an alternative to a PIC18F252.
I need to connect to 5 16bit Absolute optical encoders to read from.
