应用设计中，用一条I2C总线驱动多个I2C设备师很常见，实施也很简单，本项目将连接以下I2C设备： Adafruit_GFX, Adafruit_SSD1306.h 和 SPI.h，控制SSD1306 128×32 OLED显示屏。 由于所有元件相距不远，没必要I2C总线使用上拉电阻，因为这些杜邦线就是组件的一部分。 本项目 ...

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 ...

I2C协议是在开发中使用非常频繁的一种协议，相信大家在学习单片机的时候经常会用到支持I2C协议的模块，I2C 总线仅仅使用 SCL、SDA 这两根信号线就实现了设备之间的数据交互，极大地简化了对硬件资源和 PCB 板布线空间的占用。因此，I2C 总线被非常广泛地应用 ...

The Musical Instrument Digital Interface has a great acronym that is both nice to say and cleanly descriptive. The standard for talking to musical instruments relies on a serial signal at 31250 bps, ...

A while ago I received a couple of I/O port expander modules that use the I 2 C protocol. Using that Chinese module, you can use only the SDA and SCL pins of your ...

Step-by-step guide on designing and programming a custom I2C slave sensor device using Arduino..

I2C is a two-wire, bidirectional bus protocol that enables effective communication between one master (or multiple masters) and one or more slave devices. It is a straightforward, half-Duplex, ...
