This is the serial backpack, not to be confused with a serial handbag, for graphic LCDs, providing a simple serial interface to a full range of controls.


Description [Hide]

Backpacks used to be a totally lame way to haul textbooks and homework around, but NO MORE. Now they're can be used to haul around other backpacks, such as this unit that allows you to write some text stuff and draw some lines/circles/boxes. It'll even let you control individual pixels, so you can add trapezoids and rhombi (and whatever else you want) to your LCD's repertoire. You even have control over backlight and baud rate via a serial connection, as well as a mode that will let you reverse/inverse the display's pixels. As a bonus (everyone likes bonuses, right?), the ATMega168 processor is free for downloading, and was compiled using WinAVR, which is also free.

There's 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's open, code for the 160x128 display will run.

If you're the kind that likes to know what you're getting into, this tutorial might be pretty helpful.

Hey look, a list of features!

  • Supply voltage: 6V–7V DC
  • Current draw: 220mA (backlight at 100%)
  • Serial input: 0-5V
  • Adjustable baud rate (115200 default) with 8 data bits, no parity, 1 stop bit
  • Draw text, circles, lines boxes
  • Turn on or off individual pixels
  • Potentiometer controlled contrast adjustment
  • Backlight control

Dimensions: 2.02x1.11" (51x28mm)
