Board Information Extraction

Extract general identification and specification data from user-provided STM32 documentation PDFs.

What to Extract

• MCU part number and family (e.g., STM32F407VGT6, F4 family)
• ARM Cortex-M core type and version (M0, M0+, M3, M4, M7, M33)
• Package type and pin count (LQFP, BGA, UFQFPN, etc.)
• Maximum CPU frequency
• Supply voltage range (VDD)
• Operating temperature range (industrial, extended, etc.)
• Flash memory size and type
• SRAM size and regions
• Key peripherals list (count of UART, SPI, I2C, timers, ADC channels, etc.)
• FPU presence (single/double precision)
• DSP instructions availability
• DMA controller count and channel/stream count

Where to Find This Information

Datasheet (Primary Source)

Glob pattern: docs/datasheet/*.pdf

1. Read pages 1-3 first - the overview table on the first pages contains:

   • Part number decoding
   • Core type, frequency, Flash/RAM sizes
   • Peripheral count summary
   • Package options

2. Look for the "Description" section (typically page 1-2) for a feature summary

3. Find the "Ordering information" table to decode the full part number:

   • STM32 F 407 V G T 6
   • Family / Core / Variant / Pin count / Flash size / Package / Temperature

Reference Manual

Glob pattern: docs/reference-manual/*.pdf

1. Read pages 1-5 (table of contents)
2. Navigate to Chapter 1: "Introduction" or "Device overview" - contains features list
3. The features table summarizes all peripherals, memory sizes, and capabilities

User Manual (Board Documentation)

Glob pattern: docs/user-manual/*.pdf

1. Read pages 1-5 for board description
2. Look for "Features" section listing onboard components (LEDs, buttons, connectors, debugger)
3. Find the "Hardware layout" section for board-specific information (crystal frequency, external components)

Extraction Process

1. Glob docs/datasheet/*.pdf to find the datasheet
2. Read pages 1-3 of the datasheet to get the overview table
3. If datasheet not found, glob docs/reference-manual/*.pdf and read chapter 1
4. Optionally read docs/user-manual/*.pdf pages 1-5 for board-level information
5. Compile all extracted data into a structured profile
