stm32-dw3000-spi

What problem does it solve?

This Skill helps diagnose and fix DW3000 SPI communication failures on STM32, especially cases where device ID reads fail, chip select timing is wrong, or the radio does not respond during bring-up.

Core Features & Use Cases

• SPI Failure Diagnosis: Pinpoints common causes of 0x00000000, 0xFFFFFFFF, and random DW3000 reads.
• STM32 HAL Guidance: Explains how to use full-duplex SPI transfers correctly with proper chip select handling.
• Timing and Concurrency Checks: Covers mutex protection, interrupt contention, and SPI speed limits during initialization and normal operation.
• Use Case: A firmware engineer can use this Skill to troubleshoot a board that boots but cannot read DEV_ID from the DW3000 and quickly isolate wiring, mode, timing, or driver issues.

Quick Start

Use this skill to analyze a DW3000 SPI read failure on STM32 and identify the most likely cause from the observed DEV_ID value and transfer behavior.
