stm32h750-weact SKILL.md skillA

stm32h750-weact from alexex1993/mcu-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add alexex1993/mcu-skills/stm32h750-weact@git:20261030.816967f

Pins git:20261030.816967f in mdr.lock. Pin the fingerprint instead.

Firmware development for the WeAct Studio MiniSTM32H7xx core board (STM32H750VBT6) — its 0.96" ST7735 TFT, DVP camera, QSPI/SPI flash, MicroSD, USB, and the STM32Cube HAL + PlatformIO setup around them. Use when working on this board or any STM32H750/H743 WeAct core board: project setup, platformio.ini, clock/PLL configuration, pin mapping, peripheral bring-up, LCD performance, D-cache/DMA problems, DFU flashing, or debugging why something on the board does not work.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# WeAct STM32H750VBT6 core board

Board-specific firmware knowledge. The two reference files hold the detail — read the one you need
rather than guessing, because most of the failure modes below are silent (the board runs, just
wrongly).

- `reference/board-hardware.md` — complete hardware reference: schematic-level pin map, every
  connector, power tree, memory map, SDK/examples inventory, **plus** a full development guide
  (Part II: §12 PlatformIO, §13 clocks, §14 peripheral cookbook, §15 M7 gotchas, §16 flashing,
  §17 pitfall table).
- `reference/recipes.md` — copy-paste-ready code: `platformio.ini`, clock config, LCD driver with the
  fast blit path, backlight PWM, ADC temperature sensor, USB CDC, DWT frame pacing.
- `template/` — a **complete working project** that builds and flashes, plus a scaffolding script.
  It is where every recipe was extracted from; see `template/README.md`.

How to install

The exact contents, by fingerprint

mdr add alexex1993/mcu-skills/stm32h750-weact@sha256:4ffaceaff5aed7bb

The line at the top of this page pins the label git:20261030.816967f, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
