I2C使用了两根接脚,一根是资料线(SDA),另一根是时脉线(SCL)。 Master藉由控制SCL让Slave知道有东西要传,而资料就可以在SDA上面传送。 I2C在当初Arduino的范例里,为了亲易近人而称呼I2C为Wire,虽然后来Arduino也承认取名为Wire看来是个错误,但在Arduino的example仍然常常看到。 (Wire取名的细节请参
是指使用Arduino作为I2C从设备(slave)与树莓派(RPi)进行通信。I2C(Inter-Integrated Circuit)是一种串行通信协议,常用于连接微控制器和外部设备。 在这种场景下,Arduino作为I2C从设备,可以通过I2C总线与树莓派进行数据交换。以下是关于这个问题的完善且全面的答案: 概念: Arduino:Arduino是一款开源的硬件平台,基于简单易...
