Node-Red on Raspberry pi 4 GPIO & Serial Port Issue

Open Quicksilverzone opened this issue 2 years ago • 3 comments

Hi,

I prepared openwrt image including node packets in these repo. But I cannot control GPIO and serial ports over Node-Red, it gives error on debug windows when I deploy the script on Node-Red with the gpio or serial node. Is there any other point I need to change or configure I dont know. I am using raspberry pi CM4. I am a little bit newbie on openwrt platform. I'll be grateful for any help. Thank you.

Hi @Quicksilverzone

Sorry, but I don't know much about it and this may give you a hint. https://nodered.org/docs/faq/interacting-with-pi-gpio

I saw the error message in the image you attached. Try running this on the target machine.

npm install raspi-io
