I2C LCD Shield Kit documentation request

Post by brewforce »

I was unable to locate any documentation for this item, http://www.adafruit.com/products/772. Can someone please provide documentation on device control (command registers, etc)? I could go through the library, but that would be very time consuming and I will be using this device with another MCU. Thank you

The documentation for the shield is here: http://learn.adafruit.com/rgb-lcd-shield/overview
If you want to port to another processor, you may want to start with the existing library as a reference: http://learn.adafruit.com/rgb-lcd-shield/downloads
Data-sheet level documentation for the port expander and display can be found in the links on this page: http://learn.adafruit.com/rgb-lcd-shield/parts-list

This is what I was looking for. What a nice little chip. I will have to invest in a couple of these (probably SPI though). The whole purpose of this is learning experience, so I will attempt to create the "library" myself (project will be in C, not C++). It seems fairly straight forward and I will probably not need to take a look at the adafruit library. I may go back later to see how you guys implemented it and how far off I am.

Thanks again Bill

The library uses very little of the more esoteric features of C++. Most of it you will recognize as good old C.
