    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.

    An unattended agent bench bricks an RP2040's USB, and software alone cannot bring it back

    On FastLED's unattended bench, an RP2040 stopped enumerating over USB after it was flashed with an I2S microphone sketch. Elevated device restarts and disable-enable cycles all failed. The issue says a port restart resets the bus but never cuts VBUS. The follow-up lists a switchable hub, an SWD probe and a watchdog that falls back to BOOTSEL.
