- some minor changes in structure of repo, added some info about versions & photos
- 2016-08-05
- I decided to add change log section :D
- Added info for reverse engineered init for v5 lcd in
tests
- 2019-06-21
- Updated some info (including v6.3)
I had in plans to create a custom driver but I decided this is not worth my time. I'm going to "re-interface" this lcd to be supported by fbtft. I have a prototype pcb with fbtft-spi interface ready (I have to send this project to pcb prototype service).
** I might periodically update this repo but I consider kedei display as waste of time and money so don't bother me about them 😉 **
There is 8 version already each one is built on different LCD display, constant is:
- SPI to LCD interface
- draw commands (cmds for setting draw window in lcd)
I have moved data from lcd-photos to lcd-module-info and groupped informations (and kernels) by lcd version.
I have written for v1 some test routines that init lcd and draw few colors using different drivers (python, libbcm2835, linux-spi).
Unfortunatly, because of my "spider-circuit" I've broken my lcd (I've made a some short 😢 ), but my v1 pcb adapter (one-side pcb with wire jumpers) works identically like the spider-like circuit so I assume the circuit is ok and connections too, but lcd gone bad... See photos in hw-hack\v2.1\results :)

- I have created a "backup" repo for kedei sysimages: https://www.mediafire.com/folder/t709uvp6a3ftb/kedei-sysimg and kernels: https://www.mediafire.com/folder/t709uvp6a3ftb/kedei-sysimg
- Topic on raspberrypi forum: https://www.raspberrypi.org/forums/viewtopic.php?f=44&t=124961 - you can get there help, but first check whole thread because your question might be already answered.
This is probably end of me playing with KeDei lcds. From this point, I'm going to buy next displays that are nativly supported by fbtft 😄 (and fbtft is now part of official raspberry pi kernel 😄 ).
