ロボカップジュニア レスキューラインでは2個の緑色マーカーを検出する必要があります。 お手頃価格のI2Cカラーセンサー(TCS34725カラーセンサーモジュール)があるのですが、アドレス切替機能がセンサーには無いので2個並べる事ができません。 " Arduino ...

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 ...

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 ...

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, ...

This library is written to use the NXP PCF85263 RTC. The functionality implemented is just basic date time retrieval. The device can run in a stop-watch mode. The range goes up to 999 999 hours, which ...

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 ...

This SD2405 library provides a interface to read and write the date and time to and from the I2C SD2405 RTC device and compatibles (SD2405AL). Furthermore one can set alarms in many formats. An unique ...

It’s not much of a stretch to assume that the majority of Hackaday readers are at least familiar with I2C. In fact, there’s an excellent chance that anyone who’s ever done more with an Arduino than ...

A lot of great ICs use I2C to communicate, but debugging a non-working I2C setup can be opaque, especially if you’re just getting started with the protocol/bus. An I2C bus scanner can be a helpful ...
