This is an old revision of the document!
This document explains about the hardware and software setup, which is required to interface a LCD (EADOGM128W6) with the EV-COG-AD3029LZ through SPI interface.
The hardware details cover the COG jumper settings and also the pin mapping between the LCD (EADOGM128W6) and the EV-COG-AD3029LZ. The software details cover the software development kit required and the software architecture of the code base written to interface the LCD with the EV-COG-AD3029LZ.
This section contains hardware related information about AD-GEAR-DISPLAY1Z and the EV-COG-AD3029-LZ. Links are provided to the WiKi page of the target COG-AD3029-LZ, the Schematics, BOMs and technical documentations at the end of this page.
