Hello everyone, I am a newbie sorry if this is posted in the wrong forum. I just purchased a serLCD from sparkfun that says it can run off 3.3v source. I have a USB programmer that I have fed the two spy biwire connections and power to a breadboard to program a DIP MSP430. I am also powering the serLCD with this source and have a software implemented UART on my MSP430. I have set the DCO to 1MHZ and the and the timer_a to run at 9600 baud. When I supply power to the serLCD all I have is a screen with the backlight on, nothing is displayed. I try to send information through my software UART off of P1.0 and nothing happens. I currently have it configured for 8N1 communication does it need to be 1 start 8 data and 1 stop? Should jibberish be showing on the screen when I have it powered up? Am I not delivering enough power? Thanks!
