There havae been past discussion by me and others about using the internal RC osc for a buad clock. I do have a 4mhz resonator but I pulled it off thinking I could use the internal clock but... Seems that data is not transmitting correclty...dropping characters, or wrong characters. I havent looked at it with the scope yet, just wondering if there is some initial issue with using the internal clock. I have a pattern just looping to transmit and thats what I'm watching. From what I can see, the TXREG always holds the correct data. Scope is next...see what the timing actually looks like. Is the code correct? I'd say yes, only since it is transmitting something and sending out the uart isnt that difficult. --------------------------------- TV dinner still cooling? Check out "Tonight's Picks" on Yahoo!
