Iridium SBD is Mikal's original library which does not (currently) support I2C. The Iridium 9602 and 9603N are fascinating communications modules that give devices like Arduino or Raspberry Pi™ access ...

This library is to use an HC4067 multiplexer by means of a PCF8574 (I2C 8 channel IO). The HC4067 allows e.g one analog port read up to 16 different analog channels, or one digital port to read the ...

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 ...

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 ...

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, ...

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 ...

Arduino has just launched a “Plug and Make” kit designed for beginners with an Arduino UNO R4 WiFi board, several “Modulino” modules, a “Modulino” base to neatly attach the UNO R4 and modules, and ...
