This project brings support for the ESP8266 chip to the Arduino environment. It lets you write sketches, using familiar Arduino functions and libraries, and run them directly on ESP8266, with no ...

In case you missed it, the big news is that a minimal Arduino core is up and working on the ESP32. There’s still lots left to do, but the core functionality — GPIO, UART, SPI, I2C, and WiFi — are all ...

I’m testing the HT-HC32 HaLow node using the Heltec-supplied esp_halow Arduino core. The board is recognized on COM5, but any sketch — even an empty one — fails to compile due to unresolved symbols ...

シングルトンパターンのオブジェクト（SD_MMCなど）をどのように扱うか悩む 簡単さを重視して、かなり密な依存関係にしてしまった 「FreenoveSDクラス」を「esp_camera」に依存させてしまった Serialオブジェクトをライブラリ側に渡す良い方法が思いついてい ...

My first foray into the IoT utilized the Espressif ESP8266, an SoC with 32-bit MCU and 2.4-GHz Wi-Fi built in. Since then, I have used many different module variants based on the microcontroller. So ...

Arduino has introduced a Nano shaped board with a Wi-Fi and Bluetooth LE capable Espressif’s ESP32-S3 microcontroller, supporting it with the Arduino IDE and MicroPython. “Beginners can explore in an ...

If you have an RTL-SDR compatible radio there’s an excellent chance you’ve heard of the rtl_433 project, which lets you receive and decode signals from an ever-expanding list of supported devices in ...
