Re: [oopic] Re: oSerialL - Really confused

George,

The PIC MSSP is unable to do async. serial, so that isn`t an option.

DLC,

No problem. I just ordered a converter from Pololu. I am not sure
if the problems are with the ooPIC-R or the Daisy MP3 player, but
they don't seem to want to talk to each other. Do you know if the I2C
network connector can be used for async serial IO to another device?
