PSA: If you're a fan of ATmega, try AVR Dx
A little-known offshoot of the ATmega series of 8-bit microcontrollers is better, faster, and cheaper than its progenitor.
In recent years, their market position has been challenged by single-board computers and the wi-fi-capable ESP32; still, the AVR architecture remains the go-to option for those who want to get things done without wrangling schedulers or debugging congestion on the Cortex-M AHB. The new chips also feature reduced power consumption, better ADCs and DACs, on-board op-amps, and programmable LUT-based logic units that can implement real-time automation without involving the CPU. If you prefer to learn from examples, I also published the source code for two of my earlier AVR Dx projects: an audio toy and an OLED game.
