wiointerface
Wiointerface is library for developing and tinygo software for wio terminal. This is private "under development release" for making applications using this library. There will be interface compatility breaks at future
Idea of this library is to allow compile microcontroller software on tinygo and test/demo version for pc
On PC libsdl interface lsA,S and D keys are 3 keys on top of wio terminal. Arrow keys match to arrow pad on wio and return key is "press joystic down" button
Demo programs
Demo programs under cmd directory are compiled with command
tinygo build -target=wioterminal -o out.uf2
I personally use script to
mkdir -p mountti
mount /dev/sda ./mountti/
tinygo build -target=wioterminal -o ulos.uf2
cp ulos.uf2 ./mountti
umount ./mountti
Building demo on PC is just
go build
Test programs
- ambient just shows how to use BME280 on wio terminal (left side I2C connector)
- chip8 is just chip8 emulator
- marijodemo just drawing some scrolling sprites

Overview ¶
Thin wrapper for wio terminal.
Instead of having custom made machine package etc... have some interfaces For some reason machine package is in included in devices. Very non testable situation
Interfaces also allow more high level abstraction instead of playng with device registers ¶
Actual implementation on hardware is simpler than what comes from ili9341 ¶
