I want to build my own portable E-Reader like a Tolino/Kindle in DIN-A5 format (I know there are similar projects, like the Open Book from joeycastillo, but I want to make my own just for fun). I’m considering using the Compute Module 4 from Raspberry Pi. That, at least according to my theories, would have the advantage of me...

I’m trying to run an LED matrix display (with a Max7219 controller) from a raspberry pi pico using rust. There is a max7219-crate that I used. But i am unsure about how to prepare the pins I want to use. Can I Use any of the pins? Do I have to set them to push-pull-output?

The hardware team needed to make some modifications to our prototype PCBs. Unfortunately resulting in two cold solder joints. The board worked for a while but then had issues after a few thermal cycles. Debugged the code for hours before realizing it was a hardware issue....

Building a sailing starter board with Rust (RTIC)

WCH produces ultra-low-power MCU such as the CH582 or the CH32V208, among others. Their SDK includes examples and libraries to use BLE, and these libraries use a proprietary scheduler called TMOS. Unfortunately, there's no documentation about it outside code examples....

I like to play with STC's 8051 MCU for fun and have developed a HAL for them covering all STC8 and STC15 series, and the STC12C5A56S2 family. Here it is....

In the past this was the most recommenced FOSS logic analyzer and data-logging software for electronics, but it seems the most recent update was in early 2021, and even the nightly build has been down for months. Are there any good alternatives that are still being actively developed?

I maintain a list of available RISC-V MCU and development board, including purchase URL and pointers to documentation and SDK, so that someone willing to try RISC-V finds all the relevant information at a single place....
