The current input on the device are five SMD buttons on the front but this is something that I want to change. These buttons are turned into keyboard input by retrogame.
The case exists of two parts and these are put together using three 2mm screws. All the parts inside the case are press fit and all the ports are accessible from the outside of the case.
|GPIO 11 (SCLK)||SCK|
|GPIO 10 (MOSI)||MOSI|
|GPIO 8 (CE0)||CS|
I shorted J1 on the back to enable the 3.3V input and bypass the voltage regulator. To use the display you need to enable SPI, enable the backlight (GPIO 23) and initialize the fbtft driver.
initialize the driver:
sudo modprobe fbtft_device name=sainsmart18 bgr=0 rotate=270
