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 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 ...

[Wayne] wrote in to share an item he just finished working on, an I 2 C GPS shield for the Arduino. While other GPS solutions have existed for quite some time, his caught our eye due to its feature ...

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 ...
