At the heart of the ESP-01 module is the ESP8266 chip with at least two boot modes — the normal mode and the programming/flash mode. The latter refers to uploading any software (or firmware) to the ...

Small arduino program I wrote to start learning a bit about embedded. It uses an ESP-01 to connect to your local wifi and the free to use weather api to parse out information for local weather like ...

”ESP32MCU”のプログラム開発には、"Arduino IDE"、”ESP-IDF（Espressif公式フレームワーク）”、”MicroPython”の3通りの開発環境が一般的です。 この記事では、Arduino IDE と ESP-IDF をどのような要件で使い分ければよいかを、組込み開発の観点で 明確な判断基準 と ...

ESP-01 is a tiny and useful piece of hardware. It has a 32-bit MCU, 2.4GHz 802.11 b/g/n WiFi, 1MB flash memory, and several other useful embedded features. Such ...

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 ...

As USB-C PD becomes more and more common, it’s useful to have a tool that lets you understand exactly what it’s doing—no longer is it limited to just 5 V. This DIY USB-C PD tool, sent in by [ludwin], ...

ESP32-C2 and ESP32-C61 are also supported by Arduino-ESP32 but require using Arduino as an ESP-IDF component or rebuilding the static libraries. For more information, see the Arduino as an ESP-IDF ...
