Webnpm install node-red-node-pi-gpiod An alternative pair of Node-RED nodes to interact with Pi GPIO using the PiGPIOd daemon that is now part of Raspbian. The advantage is that it also talk to GPIO on a Pi that is remote as long as it is running the daemon, and also sharing pins works more cleanly as contention is handled by the multiple connections. WebApr 6, 2024 · 上一节将到将普通gpio设置为输入,app端可以通过轮询的方式去读取外部设备的状态,但这样消耗的资源比较大。如果采用中断的方法,当gpio高低电平发生变化的时候,我们再去处理相应的事件,那么会大大降低cpu的负担。kernel版本:orange-pi-5.10-media。那么串口会每隔一秒打印一次中断处理函数。 hackney otherworld https://taylormalloycpa.com
