This repository contains a simple I2C LCD driver for ESP32 microcontrollers written in C. The driver allows interfacing with I2C-enabled LCD screens using the ESP-IDF framework. Prerequisites Before ...

(See the README.md file in the upper level 'examples' directory for more information about examples.) This is the simplest buildable example. The example is used by command idf.py create-project that ...

Using hardware I2C on an ESP32? Do you need to connect multiple I2C devices with the same address? Normally, you wouldn’t be able to do that without extra parts, but on the ESP32, [BastelBaus] has ...

今日はESP32をマスター、PICをスレーブ としてESP32からPICにデータを転送してみます。💪 ESP32からデータを転送して、そのデータ値でLEDを点滅させたいと思います。 I2Cの通信規格はネットで調べるとたくさん出て来るので、今回は省略しますね。 1、回路図 ...

ESP32をマスター、PICをスレーブ の状態でとして今度はPICからESP32にデータを送信してみます。💪 PICからESP32にデータを送信と言っても、I2Cの場合はPICの送信タイミングはESP32がリクエストすることになります。つまりESP32が『俺にデータを送ってこい』ってPIC ...
