ラズパイやArduinoでセンサーなどを使うときにI2C通信がよく使われています。この場合、ラズパイやArduinoがマスターで、センサーがスレーブになって、マスターからスレーブのデータを書き込んだり、データを読み出したりします。 センサーなどの代わりに ...

Assume that you are moving towards a complex microcontroller project bundled with blinkers, beepers, and a display panel. To link a standard 16×2 LCD directly with the microcontroller, for instance ...

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 ...

An Arduino library for I²C device operations. This is an abstraction class which can be used for all I²C devices to manage access at the register level. In addition to the device abstraction, it ...

The two SCD41 sensors we want to connect have an I2C address of 0x62, which cannot be changed. Therefore, to communicate with both sensors from the micro controller, we will use a separate I2C bus for ...

The Challenger RP2040 WiFi is a microcontroller board from iLabs. It combines a Raspberry Pi RP2040 microcontroller with an ESP8285 for Wi-Fi connectivity. The board has two LEDs, one of which is a ...
