ESP-IDFを使って、I2Cをサクッと実装しようと思ったら、理解があいまいで想像以上に時間がかかって、泣きそうになったので、ここでまとめておく。 I2CのArduino FrameworkとESP-IDFの違い I2CのESP-IDFのVer.4系とVer.5系の違い 構造体のC++とC言語での初期化の違い ...

Arduinoで人気の小型ディスプレイ「OLED」。いざ接続して、よくあるLCDのサンプルコード（LiquidCrystal_I2C.hを使うもの）を書き込んだら、fatal error: LiquidCrystal_I2C.h: No such file or directoryというエラーが出て動かない…。 このエラーメッセージだけを見ると ...

This articles describes how you can use I2C (TWI) communication, Arduino and temperature sensors to measure 3 different temperatures. It can be very helpful when you want to measure the outside, ...

The I2C (Inter-Integrated Circuit) bus is a synchronous serial communication protocol that allows multiple electronic components (sensors, displays, memories, etc.) to be connected within the same ...
