Hi - I wonder if anyone can offer any insight into this problem?
Pi 4B, Raspbian 10 (buster)
From a fresh reboot
i2cdetect -y 1 (see pic)
Start Node-Red (and do nothing else - I don't have any i2c nodes installed)
i2cdetect - y 1 (second half of the pic)
It seems Node-Red is ? corrupting the bus maybe
I have a python scrip that interacts with the i2c bus - works before I start Node-Red but won't work afterwards.
I'm also unable to stop Node-Red from the command line
Just sits there having made no apparent change (browser page still works)
node-red-log doesn't do anything either.
I've been unable to get the i2c nodes to work at all in Node_Red
I suspect I have stuffed up the node-red installation somewhere.
Any advice appreciated.
