WebJun 15, 2024 · This time GPIO input pin was correctly started. Sometimes it is "stopped" and it can happen after Raspi is restarted or after deploying flows. Actually when developing other flows and deploy changes I usually check Doorbell flow to see is GPIO14 running. All I can say that sometimes is stopped (red) and next restart flows or developing further ...

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
