I've created a draft of the device using bread-board to check if I correctly connected LCD to stm32 nucleo and to have something to do driver development before ordering PCB. In addition I've added to the board up/down/left/right keys.
Connections changes to original schematic:
- RST - PC7
- DC - PA8
- CS - PB2
- up - PC3
- down - PC2
- left - PC14 (TODO: move it somewhere else)
- down PC15 (TODO: move it somewhere else)
I've also tried to solder the part responsible for dimming the LCD but having only MOSFETs in SOT-23 package, it seems to much to work.
