SparkFun will be closing early at 3:30 Friday 5/27 and remain closed Monday for Memorial Day (5/30). Orders placed after 2pm MT on Friday (5/27) will process and ship out on Tuesday (5/31).
Description: This is the serial backpack for graphic LCDs. The SparkFun Graphic LCD Serial Backpack interfaces to either our 160x128 pixel “Huge” Graphic LCD, or the smaller 128x64 pixel display, and provides a simple serial interface to a full range of controls.
This backpack will allow you to write text, draw lines, circles and boxes, set or reset individual pixels, and erase specific blocks of the display. The backlight and baud rate can also be controlled via serial communication. There’s also a reverse mode that allows the screen to operate blue on white instead of white on blue. Additionally, all source code for the ATMega168 processor is compiled using the free WinAVR compiler and is free for downloading.
There is a solder jumper on the backpack that determines which display is used. When the solder jumper is closed, code for the 128x64 display will run. If the jumper is open, code for the 160x128 display will run.

There may be other devices out there that do what this backpack does, but I haven’t found one nor done an exhaustive search. This device is a great idea, as are so many Sparkfun products, but the firmware is buggy! After struggling with my work-arounds for a while, I decided to download the Jenn Holt firmware from Sourceforge. Her feature set is a super-set of the Sparkfun features, and every one I’ve tried works as advertised. I’m not an Arduino or Atmel guy, but I was able to get it downloaded and running using the “eXtreme Burner - AVR” software and a $7 burner from eBay in no time. Give it a shot. You’ll end up with an extremely functional device afterwards. I continue to buy these devices, but the first thing I do is re-program the firmware! (One caveat: Her firmware only works with the 128X64 display.)
