Nice work! I've been trying to stand up nesper/nephyr, the Nim overlays for ESP32 and Zephyr, but had quite a few issues (not all of which are those library's fault, the ESP-IDF toolchain is horrid in a lot of ways). I wonder how difficult it would be to extend Ratel over to ESP32 if I have a working toolchain already. I might have a crack at it, we're big on Nim at work and are trying to get away from C++ for our firmware development wherever possible.

To be clear: Ratel isn't my project, just something I'm following due to interest. In the interest of shameless self promotion :), my own experimentations are : https://github.com/EmbeddedNim/svd2nim https://github.com/EmbeddedNim/svd2nim https://github.com/auxym/nim-on-samd21 https://github.com/auxym/nim-on-samd21 And I've used and contributed to picostdlib (https://github.com/beef331/picostdlib https://github.com/beef331/picostdlib), the rp2040 support library. All just as a hobby, but it's interesting to learn that some companies are actually looking into Nim for firmware! Embedded seems like such a slow moving industry. I believe the author of Nesper and Nephyr also developed them for professional work.

  As an update, after ditching the project/build tooling setup that Nesper required, I got Nim working wonderfully (with Nesper's library itself as a dependency) within PlatformIO and ESP-IDF on an ESP32 :) I even have hardware UART support and have a working SIM7000 modem connection going (though only with AT commands, not PPPoS yet, though I'm planning on that next). Nim is the future of firmware development, of that I am sure.

  Incredibly slow moving, buggy and badly documented! Embedded is a fun challenge but rough. Nim I believe is an answer to it though, and embedded being slow moving with a C target is perfect for it!
