Interface
The short-range buses that connect sensors, displays and memory to a microcontroller, and the bugs agents help find on them.
The most active tools first.

Tramuntana is an open bench tool built on the RP2350 (Raspberry Pi Pico 2) and Zephyr that works over one USB cable. It has SPI and I2C master and sniffer modes, a 2-channel 500 kS/s scope, a waveform generator, an 8-channel logic analyzer and a UART bridge. Its Python package adds an MCP server. The README shows no captures.

Agent Fingers runs on a stock Raspberry Pi Pico 2 as a signal instrument and CMSIS-DAP debug probe for AI agents. It offers eight digital channels, ADC capture, PWM, UART, I2C and SPI, plus SWD and JTAG for STM32 and ESP32 targets. Outputs need an expiring arm lease. The README shows no hardware runs.

bus-mcp runs on a Raspberry Pi and exposes CAN, CAN-FD, RS-485, UART, I2C, SPI and GPIO as 18 MCP tools. Buses are read-only until writes are enabled for chosen bus kinds. An installer sets up a systemd service with an HTTP endpoint. The README gives a loopback test procedure but no recorded results.

AIX Skills collects 76 agent skills for embedded work, from 8051 and Cortex-M debugging to CANopen and cellular AT modems. Each skill gives an agent trigger conditions, a step-by-step workflow and checks, and the repo adds templates for writing new ones. The skills are instructions only, and the README shows no runs on hardware.
Ranked by points weighed against age. New entries with early votes rise.

Ori Grossman built a tilt maze game on a PIC24FJ256GA705 Curiosity board with Claude Code agents, an ADXL345 accelerometer and a 96x96 OLED. One agent drove the board's debugger through MPLAB's mdb command line and traced an I2C driver bug that dropped queued bytes. The README has a photo of the game running.

Jacob Beningo gave Claude Code his Zephyr skills and a serial-port MCP server, then had it debug a sensor application on an NXP FRDM-MCXA156. The agent first blamed the hardware, and Beningo found the Click board mounted backward. Claude then traced readings of -45 C and 0% humidity to a conversion-timing bug. A screenshot shows its 83-sample check.

XDA's Anurag Singh used Claude Code to plan an ESPHome multi-sensor on an ESP32-WROOM-32 DevKit. It put an LD2410C mmWave sensor on UART pins and a BME280 and BH1750 on shared I2C pins, then wrote, validated and compiled the YAML. He says the device then reported to Home Assistant. The article shows screenshots, not the build.

RRF_Claude collects plain-English guides for non-programmers doing hardware work with Claude Code. One compiles RepRapFirmware for Duet3D printer boards on Windows or macOS and adds features to it. Another wires two PN5180 NFC readers to an ESP32 while the agent writes firmware for Bambu Lab and OpenPrintTag spool tags. The repo shows no photos or build results.

Tech-AD-venture's 65-minute video walks through wiring sensors to an ESP32 over I2C and UART and defining a JSON command protocol on the serial link. It then builds a FastAPI-based MCP server so an LLM called through the OpenAI API can read registers and send commands. We have not watched the full video to confirm the hardware segments.

Seif Salama built an Ackermann-steered robot that runs one ROS 2 Humble stack in Gazebo Harmonic and on a Raspberry Pi car. A custom ros2_control interface drives the motors over UART and the steering servo over I2C. A Gemini or Ollama agent takes spoken commands. We could not tell whether the README video shows the physical robot.
