Wokwi-example with usage of my colegue's, Samuel Benko's, beautiful graphic examples (check here), but adapted for famous ili9341 display)

Instructions

cargo build --target riscv32imac-unknown-none-elf --release

Execution with VSCode Wokwi extension

Except of extension itself, you will need two files to execute the simulatuion inside of your VSCode IDE:

• wokwi.toml
• diagram.json

Both of them are already provided in this repo and you can edit them as needed.

F1 -> Wokwi: Start simulation

In case you will have additional questions - feel free to open an issue 😉

Description

There's a short example for newcomers that shows, how 8x8 LED Matrix display is initialised on different Espressif boards (ESP32, ESP32S2, ESP32C3) in bare-metal, this config is for ESP32 in terms of example, you can find brief instructions for other chips below

P.S. : Buttons on left are up and down correspondingly, button on top is ok. After image finished rendering press ok button to return back to main menu 😉

Tips for other chips

For esp32 board target (and corresponding changes for paths in wokwi.toml) is:

xtensa-esp32-none-elf

Board type in diagram.toml is:

"type": "wokwi-esp32-devkit-v1"

---

For esp32s2 board target (and corresponding changes for paths in wokwi.toml) is:

xtensa-esp32s2-none-elf

Board type in diagram.toml is:

"type": "board-esp32-s2-devkitm-1""

---

For esp32s3 board target (and corresponding changes for paths in wokwi.toml) is:

xtensa-esp32s3-none-elf

Board type in diagram.toml is:

"type": "board-esp32-s3-devkitc-1"

Troubleshooting

• For xtensa targets you need to have esp-idf exported in your terminal
• In case of errors, related to esp-hal driver - try to play with dependencies versions on Cargo.toml. Sometimes there're a lot of breaking or light changes, that can affect building process
