Description
This Serial Enabled LCD Backpack by Sparkfun allows you to control a basic LCD screen over a single-wire serial interface. The SerLCD backpack takes care of all the HD44780 commands allowing seamless integration with any micro that can communicate over a wide range of TTL serial baud rates. The SerLCD currently supports 16 and 20 character wide screens with 2 or 4 lines of the display.
Communication with SerLCD requires 5V TTL serial at a default baud rate of 9600bps (8-N-1). You can adjust the baud to any standard rate between 2400 and 38400bps. The power, ground, and RX pins are all broken out to a 3.5mm pitch screw terminal.
SerLCD has the ability to dim the backlight to conserve power if needed. There is also a potentiometer on the backpack to adjust the contrast.
Note: The datasheet incorrectly identifies the PIC as a 16F688, when it's actually a 16LF88.
