After our previous musings about adding a expansion interface we're made a our first add-on: An LCD unit.
The LCD is a 2.4" module used is a pretty common one you can find on various on-line stores (Adafruit, eBay etc.). It's enclosed in a laser cut case that has an extended "lug" that's designed to slide into a slot in the R-Kade Zero's case. This creates a mechanical support. A pair of connectors mate together on the LCD unit and R-Kade Zero controller board to hold the two units together.
- Format the SD Card and write the Retropie image onto it - Boot Retropie - Set up your input device either a keyboard or a controller - Using left & right buttons/keys scroll to the Retropie logo and press 'A' button - Scroll down the list where to the Retropie Setup option and press 'A' again. - Choose which emulators you want to install from the menu options - Wait for the emulators to install (takes sveral minutes) - Reboot Pi
Once we were happy with the prototype, two PCB (printed circuit boards)
were designed, one with a single joystick and 4 control button which we
called JS/4 and a second with just two joysticks which we called 2STIKS.
Yeah we know pretty original names (or perhaps not). We had PCB's made
from these designs and used DirtyPCB's and also Smart Prototyping to get them made.
