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 ...

秋月電子で購入したBOSCH社製9軸センサ「BNO055」を実装したセンサーフュージョンモジュール「AE-BNO055-BO」を使用し、「Arduino UNO R4 MINIMA」とI2C通信を行いました。が、動作確認できるまでに少々苦労したので備忘録としてまとめました。 下記が回路構成です。

PJON, pronounced like the iridescent sky rats found in every city, is a cool one wire protocol designed by [gioblu]. [gioblu] wasn’t impressed with the complications of I2C. He thought one-wire was ...

The Arduino platform offers a variety of affordable toys used by DIY enthusiasts for simple electronics projects. It is known for being easy to learn and is built on a variant of the C++ programming ...

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 ...

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 ...

The I2C (qwiic) interface for the SparkFun Fingerprint Sensor - FPC2534 Pro board is currently only supported on ESP32 and Raspberry RP2 (RP2040, RP2350) boards. The I2C implementation of the FPC2534 ...

The Arduino is a powerful platform for interfacing with the real world, but it isn’t without limits. One of those hard limits, even for the Arduino MEGA, is a finite number of pins that the ...

An upstream I2C issue remains open and needs to be fixed before we can again use the latest stable Arduino-ESP32 version. I2C Fail 3.2.0 espressif/arduino-esp32#11228 ...
