Really nice to know that this year at GitHub Universe, the hackable badge is a customized version of @pimoroni.com Tufty, but in this case, instead of based on RP2040, now it is RP2350.

Your @GitHub Universe badge comes with a hackable Raspberry Pi built into it with full color display, 5 buttons, USB-C, Bluetooth, and WiFi.

After some time, research, and a lot of reading schematics, along with many code examples in C/C++, Go, and Rust, I’ve finally managed to make the @pimoroni.com Tufty 2040 work with embassy-rs and embedded-graphics. It was full of challenges, especially because it uses a Parallel Bus instead of SPI.

It is funny to learn new things. Debugging a new PCB, today I finally had the opportunity to learn a bit how to use an oscilloscope. Together with it I realised the PCB I am working isn’t transmitting enough energy from one point to another. Checked on multimeter and confirmed in the oscilloscope.
