🦀 Short intro to Rust Embedded Development 🧵👇
I'll be using:
* STM32F407G-DISC1 microcontroller (Cortex M4)
* cortex-m crate crates.io/crates/corte...
* stm32f4 crate crates.io/crates/stm32f4
The goal is to write a simple Rust program that enables some LEDs.

🦀 Short intro to Rust Embedded Development 🧵👇 (part 3)
I'll be using an STM32F407G-DISC1 microcontroller (Cortex M4) and two main crates: cortex-m and stm32f4.
The goal is to write a simple Rust program that plays with the LEDs and button of the board.

Hell yeah :D TIL the STM32F411 has a wlcsp package.
It's an older part, and the STM32F4 sure has some quirky errata, but it's pretty well supported by embassy-stm32. I'm definitely interested in following along :D

does anyone have experience reverse engineering firmware? I have an update file with the firmware for a device using an STM32F4, I can find the strings I'm interested in within the firmware, but I can't get Ghidra to find where those strings are being referenced.
