Top 23 C++ Esp32 Projects

  • Marlin

    Marlin is an optimized firmware for RepRap 3D printers based on the Arduino platform. Many commercial 3D printers come with Marlin installed. Check with your vendor if you need source code for your specific machine.

    There is _a lot_ wrong with Marlin. It is a complex codebase, full with ancient artefacts, litterred with preprocessor ifdefs every 2-3 lines of code, dynamic includes in the middle of CPP files, etc[1]. It's about as unreadable as C++ code gets--well, I guess it's not template metaprogramming.

    Klipper by contrast is a breeze to read through[2].

    I am very grateful for Marlin, for all of reprap, and everyone who has contributed to it. But saying there is nothing wrong with it is straight up misguided.

    • Project mention: Any good/worthwhile Camera sensor modules for arduino/pico for still photography? | /r/diyelectronics | 2023-12-11

    You could just buy ready-made ESP32 boards with an OV2640 camera built-in, then customize the example sketch from https://github.com/espressif/arduino-esp32/tree/master/libraries/ESP32/examples/Camera/CameraWebServer to your liking.

  • esphome

    ESPHome is a system to control your ESP8266/ESP32 by simple yet powerful configuration files and control them remotely through Home Automation systems.

    • Project mention: A Beginner's Guide to the ESP8266 | news.ycombinator.com | 2024-04-24

    For the ESP32, an hero is in the process of adding LVGL to ESPHome. You can try it out now: https://github.com/esphome/esphome/pull/6363

    Here's the (very good!) preview documentation: https://deploy-preview-3678--esphome.netlify.app/components/...

    This is such a game-changer for me that I'll be using the ESP32 over the ESP8266 for any projects involving displays from now on.

  • IRremoteESP8266

    Infrared remote library for ESP8266/ESP32: send and receive infrared signals with multiple protocols. Based on: https://github.com/shirriff/Arduino-IRremote/

    • Project mention: I built an offline smart home, and why you should too | news.ycombinator.com | 2024-01-11

    I am planning to do this soon(TM).

    Probably starting with ESPHome to control my heat pumps over IR.

    The remote works but I forget to turn it off when not in one of the rooms, and it can't do smarts like keeping temperatures in desired bounds.

    An ESP32 running ESPHome with high power IR LED, a presence sensor, temperature sensor, and some pre-built library to control heat pumps[1]. it looks like it should be fairly simple to implement with Home assistant.

    Now if I could only disable the beep from the heat pumps receiving commands.

    I would like to do smarter lighting, but the lack of decent smart light switches that support local control and are also licenced for use in AU are a blocker there.

  • firmware

    Meshtastic device firmware (by meshtastic)

    • Project mention: Show HN: Extend Zigbee sensor range with LoRaWAN | news.ycombinator.com | 2024-03-18

    This is a fantastic idea, thanks for sharing. I feel like LoRaWAN and LoRAMESH are the perfect solution for shuffling messaging around for home and property sensors, easily traversing a couple miles in poor conditions.

    Prior to seeing this I was thinking about how to use the Meshtastic [0] project to fundamentally provide simple UDP services for message brokering over LoRa. There are so many sensors that could easily hook or connect to devices acting as network routers that could bridge other protocols across long distances very easily.

    Have you looked at doing something similar with ZWave at all?

  • ESP32-BLE-Keyboard

    Bluetooth LE Keyboard library for the ESP32 (Arduino IDE compatible)

    • Project mention: ESP32-BLE-Keyboard Example - "does not name a type" error | /r/arduino | 2023-10-24

    I am trying to get started with the bluetooth keyboard example for ESP32. using the example, it throws the error: "Compilation error: 'BleKeyboard' does not name a type" I have tried to compile this in Arduino 1.8 and 2.2.1 and on multiple computers. all fail to compile. I even tried to downgrade the ESP32 package to 2.x to no avail. What am i missing here?

    • Project mention: Ask HN: How have you engineered the shit out of your home's front entrance? | news.ycombinator.com | 2023-11-28

    Engineering implies working within constraints. Most people in this realm only have to deal with the spouse acceptance factor as a limiter.

    Went from openhab -> homeassistant -> Node-RED. Then sprinkle in MySensors, Frigate, and Double-Take, but not on just the entrance, go for the perimeter then defense in depth.
