在MicroPython中实现一个SoftI2C类需要我们对I2C协议有一定的了解,并且需要利用MicroPython对GPIO引脚的操作能力来模拟I2C总线的时序。以下是一个详细的步骤和代码示例,用于实现SoftI2C类。 1. 研究和理解I2C协议的基本原理 I2C(Inter-Integrated Circuit)是一种串行通信协议,它允许一个“主设备”(Master)与多个“从设备...

SoftWire is a software I2C implementation for Arduino and other Wiring-type environments. It utilises thepinMode(),digitalWrite()anddigitalRead()functions. The pins to be used for the serial data (SDA) and serial clock (SCL) control lines can be defined at run-time. Alternatively it is poss...
