Alternative firmware for ESP8266 and ESP32 based devices with easy configuration using webUI, OTA updates, automation using timers or rules, expandability and entirely local control over MQTT, HTTP, Serial or KNX. Written for PlatformIO.

This tutorial shows how to use the DHT11 or DHT22 temperature and humidity sensors with the ESP32 and ESP8266 development boards using MicroPython firmware.

#define DHTPIN            2         // Pin which is connected to the DHT sensor.

This is a driver for MicroPython to handle cheap displays based on the ST7789 chip. The driver is written in C. Firmware is provided for ESP32, ESP32 with SPIRAM, pyboard1.1, and Raspberry Pi Pico devices.

I2S Sound Tutorial for ESP32

In this tutorial you learn the fundamentals of the I2S communication that is used to transfer digital sound signals and why you should use an ESP32 microcontroller for your I2S projects.

After your learn the functionality of I2S we create 3 projects where you can apply what you have learned.

Sur l’ESP32 certaines broches sont reliées à l’ADC intégré du microcontrôleur. Un ADC est un convertisseur analogique vers numérique : il revoit une valeur numérique proportionnelle à la tension mesurée.

Les compteurs Linky disposent d'une prise de téléinformation appelée TIC permettant de récupérer sa consommation électrique dans Home Assistant. Cet article décrit comment construire pour une somme modique un module permettant de récupérer les informations du Linky, basé sur ESPHome et un ESP32.

If you are browsing through the specification sheet for an ESP32 device, you might run across the term “I2S”. At a glance, you may just think that it’s another form of I2C, and the “I2” does indeed stand for the same thing, “Inter-Integrated Circuit”. But that’s where the similarity ends.

I2S is a protocol for transferring digital audio. The audio quality can range from telephone-grade to ultra-high fidelity, and you can have one or two channels.

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