An STM32 Emulator in Rust #STM32 #Emulation #Rust @nviennot

Nicolas Viennot has written an STM32 microcontroller emulator in Rust.

The goal is to simulate 3D printers, but any sort of stm32 microcontroller firmware should work.

The emulator is configured via a configuration file, see example here.

In the following example, I show how to emulate the 3D printer of the Elegoo Saturn and Anycubic MonoX unmodified firmwares downloaded from the vendor website.

This emulator is done in the context of my work on reverse engineering 3D printers so I can write a Rust firmware for 3D printers, Turbo Resin.

There are a lot of registers, precisely 1537 of them for the STM32F407. The emulator is configured via a vendor provided SVD file. This way, we can easily emulate many different STM32s without having to worry about peripheral register addresses. The emulator also uses that to display traces of all register accesses, useful for debugging the firmware.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
