Display module for E-bike
Submitted by jennifer on Thu, 07/22/2010 - 14:12
After having much trouble with the Sparkfun Graphics module, I have written firmware for it that should be acceptable for my project. However I think I will use only the LCD and make my own serial interface/carrier board. It will use the same code, but will also incorporate buttons and a connector with the correct pinout to connect directly to the battery monitoring board. I'm also planning on getting a case for the display made by Shapeways 3-D printing service. This will be my first experience with online 3-D printing, so we'll see how that goes.

Can't wait to see your controller! I have seen shapeways 3D printing at the maker faire and it is pretty cool!
I guest you are using a Arduino and what type of current & voltage sensor?
#2 re: controller
Actually the entire thing is custom. Unfortunately my schematic is a mess and unsuitable for publication at this time, or I would post it. The main brains behind the system is a Microchip dsPIC. The display will have it's own controller to serve as a graphics engine. I'm using an ATmega664 for that. Mainly because I just got done re-writing the code for Sparkfun's Graphical LCD backpack, and it was all done in avr-gcc. Check under electric bike/lithium battery monitoring for the details of the bike management system.
