[picsig] USART Problems

[steve.bunch]

Greetings,

First, I would like to thank Rich for the code he sent, it was most helpful and got me going in a different direction.

My goal is to build an APRS weather station off the back of the garage.

Unfortunately, I'm still having difficulty getting the LCD to display what I'm sending from the 16F628A.  From Microchip's literature and Rich's code I understand that it is not necessary to disable the USART to stop transmitting.  Is this correct?  I have had to reset TXSTA,TXEN or the display continuously runs over with what appears to be the character for sending zero.

Also, I consistantly get "ougga" when I try to send "HELLO".  Although I can make the chip output erattic by touching it during operation I do not believe the "ougga" is due to noise.  It looks like a letter substitution but I can't find the pattern.

Is the internal 4MHz oscillator reliable for serial communications?

Any help would be much appreciated.

Thanks, Steve (KC0GBK)
