A few weeks back, we talked about the no-nos of running I²C over long wires. For prototyping? Yes! But for a bulletproof production environment, this practice just won’t make the cut. This month I ...

If you’re reading these pages, odds are good that you’ve worked with I²C devices before. You might even be the proud owner of a couple dozen sensors pre-loaded on breakout boards, ready for ...

電子工作をするために、SPI通信とI²C通信について調べたので、 その内容を書き残します. センサやADコンバータとマイコンを紐づけるために必要な通信手段であり、電子工作をする上では避けて通れなさそうですね。 通信規格には、大きくシリアル通信と ...

Bitbang I²C sample using Arduino-Pico. This code has been made to explain how an I²C controller to can be implemanted. This code is written to use a Raspberry Pi Pico with Arduino-Pico To setup the ...

The I²C bus has been around since the 80s, and is well-supported on today’s popular platforms, including the Raspberry Pi series. Node.js makes it possible to program a web server in JavaScript, ...

USB-OLED is a simple USB-controlled 128x64 pixels I²C OLED display. The CH552E (or CH554E) microcontroller builds a USB Communication Device Class (CDC) for serial communication over USB, which can be ...

In this hands-on tutorial, learn how to interface the DS3231 RTC (Real-Time Clock) module with an STM32 microcontroller using STM32CubeIDE and display the time and date on an I²C LCD. Perfect for embe ...

Hardly any bus protocol is as widely used as the I²C bus protocol launched in the 1980s by Philips Semiconductor. However, the weaknesses of this bus system have become apparent in the course of ...
