A rusty heart beats away inside this thinking rock

Stepper drivers are used as a simpler interface to control stepper motors, here we use the esp-idf RMT peripheral to send step pulses

In the interest of repeatable builds we must create a nix derivation for a rust-esp32 toolchain

Building a clean stepper loop The steps were set up to write two values at once with a repeating pattern 00 11 00 11 pattern of on/off on…

Using an arduino uno as a logic analyzer

Diagnosing stepper timing issues with another esp32

Setting up an esp32 development environment in nixos using vscode and ESP-IDF

Let's spin a stepper motor using ESP-IDF (FreeRTOS) on an ESP32!
