Rust on the RP2350 (2024) (thejpster.org.uk)
Today sees the announcement of the latest additions to Raspberry Pi's microcontroller line-up - the RP2350 family. I've had prototype units for a while, and you can run Rust code on it today. To my knowledge this is the first ever microcontroller launch with Rust support out-of-the-box.

Ask HN: Best way to learn STM32 and embedded for beginner (ycombinator.com)
My google foo is producing garbage - Most tutorials don't go past blinky. Most suggest CubeIDE, others have suggested ChibiOS. I followed some tutorials on stmbase to get a blinky going on a ST Nucleo, but it used a HAL library and it feels like cheating.

F8 – an 8 bit architecture designed for C and memory efficiency [video] (fosdem.org)
Even in modern devices, 8-bit processors are found, but the architectures used are often not well-suited to programming in high-level languages, such as C. E.g. MCS-51 (8051, 8052) based microcontrollers in the Realtek WiFi chipsets. The f8 is an architecture based on the experience and lessons learned from maintaining Small Device C Compiler (SDCC) and the many 8-bit architectures it supports.

Demystifying Common Microcontroller Debug Protocols [video] (media.ccc.de)
Many developers know that the answer to "How do I debug this microcontroller" is either "JTAG" or "SWD". But what does that mean, exactly? How do you get from "Wiggling wires" to "Programming a chip" and "Halting on breakpoints"? This talk will cover how common debug protocols work starting from signals on physical wires, cover common mechanisms for managing embedded processors, and ending up at talking to various common microcontrollers.

Monkey Island PC speaker music player (thanassis.space)
TL;DR: I modified DOSBox to extract the frequency/delay value pairs of the Monkey Island PC-Speaker songs. I then used Huffman compression to squeeze all music inside an ATtiny85 (512 bytes of RAM, 8 KB of flash) Once I managed that, I then created a small circuit with a speaker - to play the music... ...as a gift for my nieces and nephews; whom I'll see next week after more than a year's isolation (COVID)!
