edesto-dev 0.3.0

Use Claude Code for embedded development. One command to set up the bridge between your AI agent and your hardware.

edesto-dev

You already have Claude Code. Here's how to use it for embedded development.

AI coding agents stop at the terminal. edesto init teaches them how to compile, flash, and validate firmware on your actual hardware. No extra subscriptions. No cloud. No datasheets leaving your machine.

Install

pipx install edesto-dev

Quick Start

# 1. Plug in your board and run:
edesto init

# 2. Open Claude Code in the same directory:
claude

# 3. Tell it what to do:
# "The sensor readings are wrong. Find and fix the bug."

That's it. edesto init auto-detects your board and serial port via arduino-cli. Claude Code reads the generated CLAUDE.md, writes firmware, flashes it to your board, reads serial output to verify it works, and iterates until it's correct.

You can also specify the board and port manually:

edesto init --board esp32 --port /dev/cu.usbserial-0001

How It Works

edesto init generates a CLAUDE.md that gives your AI agent the full development loop:

1. Edit code (.ino, .cpp, .h files)
2. Compile with arduino-cli
3. Flash to the board over USB
4. Validate by reading serial output from the device
5. Iterate if validation fails

The validation step is what makes this work. The CLAUDE.md teaches Claude Code serial conventions ([READY], [ERROR], [SENSOR] key=value) and gives it a Python snippet to read device output. The agent verifies its own changes on real hardware.

Commands

edesto init                                 # Auto-detect board and port, generate CLAUDE.md
edesto init --board esp32                   # Specify board, auto-detect port
edesto init --board esp32 --port /dev/ttyUSB0  # Fully manual
edesto boards                               # List supported boards
edesto doctor                               # Check your environment

Examples

Three example projects in examples/, each with an intentional bug for Claude Code to find and fix:

sensor-debug

A temperature sensor sketch with a unit conversion bug. Celsius values are correct but Fahrenheit readings are off. Claude Code reads serial output, spots the math error, fixes it, and validates.

wifi-endpoint

An ESP32 HTTP server where the /health endpoint returns JSON but with the wrong Content-Type header. Claude Code makes HTTP requests to the device to validate the fix.

ota-update

An ESP32 with OTA support. Claude Code updates the version string and pushes firmware wirelessly, then verifies the new version via serial.

Prerequisites

• arduino-cli installed
• A supported board connected via USB
• Python 3.10+
