You need to pass --gc:none when compiling so that the compiler warns you when you try to use a garbage collected type and instead of the stdlib, use the SDK facilities. Here are some libraries for embedded you can get inspiration from[1]: - msp430f5510 - Run Nim on MSP430f5510 micro-controller (6KB of RAM).[2] - stm32f3 - Run Nim on STM32F3 micro-controller (16KB of RAM).[3] - ardunimo - Nim wrapper for Arduino + LinkIt ONE SDK by Mediatek.[4] - ardunimesp - Nim wrapper for Arduino ESP8266 framework + A tool for flash, compile and make the nim project into an Arduino project.[5] [1] https://github.com/VPashkov/awesome-nim#embedded https://github.com/VPashkov/awesome-nim#embedded [2] https://gitlab.com/jalexander8717/msp430f5510-nim https://gitlab.com/jalexander8717/msp430f5510-nim [3] https://github.com/mwbrown/nim_stm32f3 https://github.com/mwbrown/nim_stm32f3 [4] https://github.com/gokr/ardunimo https://github.com/gokr/ardunimo [5] https://gitlab.com/NetaLabTek/Arduimesp https://gitlab.com/NetaLabTek/Arduimesp Also, yes abstracting a platform is a lot of pain but Nim accepts PR even for niche platforms like Haiku, Genode and Nintendo Switch. Also with the upcoming destructors, the standard library will be GC-free so much more will be usable on embedded.
