Bug writer in Swift, and now also in Rust.
Jumping back and forth between iOS/macOS and embedded systems.

Rewriting @EVOApp.io.
For this one, I’ve already solved the problem with the ST7789 and Parallel Bus using Rust and Embassy! 😊

Now, we just need @pimoroni.com and @github.com to give us that beautiful board to play with hehe.

I will open the code, just don’t do it now because I am in the middle of the mess, but the nice thing is: it will work for any board and that can make use of I2C (preferably using Qw/ST connectors), like all those boards from Pimoroni with no connectivity.

Really, really nice one!!
Currently I am working to bring Wi-Fi connectivity to the Tufty 2040 via I2C using another amazing board, the Adafruit Qt Py ESP32-S2. It is being full of challenges, but I am learning a lot!

Then get one, because that little devil is fascinating! I am playing with it using Rust and embassy-rs

Hopefully @github.com will do the same thing they did last year selling the badge afterwards 😁

The ESP 32 I’ve mentioned in the other post, is to bring connectivity to the Badger and Tufty 2040.

Welcome to the jungle!

Lately, my ass has been heavily beaten by a “blessed” ESP32 S2 to the point that it has already taken me a week to understand that little devil! Hope you’re having fun there!

Share it later, I am interested in that case you’re talking about 😁
