I2C通信协议具有简单、灵活、可扩展等特点,常用于连接各种传感器、显示屏、扩展模块等外设。 GPIOZERO是Raspberry Pi官方提供的Python库,用于控制GPIO(通用输入输出)引脚。它提供了简单易用的API,使开发者可以通过编写Python代码来控制Raspberry Pi上的各种外设,如LED灯、按钮、电机等。GPIOZERO库支持多种编程方式,...
The second tricky thing is that they use the GPIO override registers to invert the sense of the PINDIRS bits - since I2C is open collector, you turn ON the output (normally pindirs=1) for a logic 0, turn it off (pindirs = 0) for a logic 1. So you could invert all your data ...
