LLMs confidently lie about your microcontroller: board details that broke generated code
In a dev.to post, an embedded developer lists board facts that broke LLM-written firmware after it compiled and flashed. An ST7789 panel needed a 34-pixel offset. A Waveshare ESP32-C6 board shares SPI lines between its display and SD card, and ESP32 ADC2 stops working while Wi-Fi is on. The author's answer is mcu-skills, Claude Code skills for 8 boards.

XDA tests Claude Sonnet 5 and Opus 5 on ESP32 strapping-pin choices
XDA's Adam Conway ran the same ESP32 wiring prompt 15 times across Claude Sonnet 5 and Opus 5. With a vague prompt, Sonnet put a display's DC line on strapping pin GPIO2 in 3 of 6 runs, twice after naming the rule. Opus never did, though one run misstated the rule. He writes that naming the exact board helped both.
