stm32-data

stm32-data is a project aiming to produce clean machine-readable data about the STM32 microcontroller families, including:

• ✔️ Base chip information
  • RAM, flash
  • Packages
• ✔️ Peripheral addresses and interrupts
• ✔️ Interrupts
• ✔️ GPIO AlternateFunction mappings (except F1)
• 🚧 Register blocks for all peripherals
• ❌ DMA stream mappings
• ❌ Per-package pinouts
• ❌ Links to applicable reference manuals, datasheets, appnotes PDFs.

✔️ = done, 🚧 = work in progress, ❌ = to do

Data sources

These are the data sources currently used.

• STM32Cube database: describes all MCUs, with useful stuff like GPIO AF mappings, DMA stream mappings, pinouts...
• stm32-rs SVDs: register blocks. YAMLs are extracted and manually cleaned up.

Generating the YAMLs

• Run ./d download_all
• Run python3 parse.py

This generates all the YAMLs in data/ except those in data/registers/, which are manually extracted and cleaned up.

Extracting new register blocks
