making the smol-est emulation gamer - part 1
Channel: Adafruit Industries
Date: 2022-01-22

we're taking a short break from floppy disk hacking (don't worry, we're nowhere near done and this will all tie together - promise!) and working on a QT Py gamer backpack we designed. the qt py esp32 pico here plugs into the back to drive the 240x240 IPS display with an SD card slot, battery charging, and an AW9523 GPIO expender for all the buttons. we wanted to make a very smol odroid go-like since that hardware had a ton of support. we've found a great open emulation project with a LOT of emulators supported and a very easy-to-understand structure at https://github.com/ducalex/retro-go so we're having a 'go' at porting it over! we had to use esp-idf 4.2 and this is the first time we've used raw idf and...we really like it! ninja is such an incredibly fast compiler and we like the 'flash n monitor' helper. so far we've got the chip booting and the tft is kinda coming up, just need to tweak the init for the st7789 instead of ili9341.
