+⧖Here we discuss microcontrollers (MCUs), single board computers (SBCs), and their accessories, such as Atmel mega and tiny AVRs (Arduinos), PICs, ARM boards such as blue/black pill STM32, ESP8266/32s, RP2040, Raspberry Pi, and others.

>Are all microcontroller toolchains this dogshit? There's a reason that arduino was so popular. For all of its (many) faults, setup is a breeze compared to most industry solutions. No, I will not install your multi-gigabyte tool chain and shitty eclipse fork that I have to make an account to download. No, I will not buy your overpriced external programmer. There's no excuse in this day and age to not have a tiny self contained toolchain, and no excuse for any moderately powerful chip to not be directly flashable over USB. For chips/debugging without USB, there's no excuse for the tool to cost more than a few dollars. It's weird how the industry manages to merge the worst parts of 90s corporate lockdown with the worst parts of modern software bloat. More weird is how butthurt professionals get when you point it out.
