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 ...

This is possible with an I2C multiplexer e.g. TCA9548 which creates up to eight channels (think of it as I2C subnets) which can use the complete address range of the device. Drawback of using a ...

ラズパイからArduinoにファイルを送りたい場合があるかと思います。例えば、音楽ファイルとか画像ファイルとか。 あらかじめSDカードに書き込んでオフラインで渡すというので用が足りる場合は良いのですが、動作中にデータを変えたい場合もあるかと思い ...

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 Ver.6で旧型式は廃止になった 構造体のC++とC ...

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, ...
