Hi, I’m trying to display data to a sparkfun Serial LCD. I’m using a HCS08 (sorry but there wasn’t a S08 group on sparkfun so posted here), running at 8Mhz on 3.6V. The LCD is hooked up to a 5V supply but the RX pin is connected to the S08 at 3.6V directly. I’ve set up the baud rate to be around …

Well…I’m pretty sure you need 5v on the LCD. 3.6v is pushing it.
