I tried to do 'npm rebuild' and 'npm install' without good result. I don't know what to do, could someone tell me how to collect/manage the inputs/outputs? thanks. ------------------------------------------------------------------------------------------ Split from Problems with node-red-intel-gpio after updating nodes.

There is no need to install them manually - and it seems you have upgraded NodeJS to 18, which makes the pre-installed nodes incompatible as they have been built for 12. Best regards!

The problem I have is that I am making a connection to a Microsoft SQL and I need at least version 14 of node to make it. In version 14 I also had problems with the intel-gpio package, as you say. Would there be any other option to know/control the status of inputs/outputs? Thank you so much

Another way to retrieve the status of the GPIOs is to use the built-in mraa console tool. With the help of the exec node in node-red you can run console commands. I attached an example to read the status of GPIO 1 every second and convert the string output to a number. Best regards! Attachment exec_mraa.zip (159 Downloads)
