How to use DO on Node-Red (tinkeros-gpio)

Recommended Posts

Dear Sir

We are testing Tinker Board 2 with Debian 10 V2.0.3 and Node-Red v2.2.2
and we found contrib-tinkeros-gpio on Node-Red can get GPIO input from Tinker Board 2
but error when send GPIO output as below picture.

If you have experience to solve this case, could you please share for me

Hi @CyberT:

     The config table's naming of asus gpio input and output node are for Tinker Board S. And, the packages are development by third party member(https://github.com/tinycore-hisanori/node-red-contrib-tinkeros-gpio). But, i think it is compatible with Tinker Board 2 about gpio pin number.

You can replace the attachment file to /home/linaro/.node-red/node-moduels/red-contrib-tinkeros-gpio/nrgpio.sh file and asus output node would work by add sudo permission for Tinker Board 2.

Please help to try and verify it. 

Thank a lot!

Hi @yi-hsin_hung 

Thank you very much for your information and help to modify nrgpio.sh for me.
we stop node-red service and replace the nrgpio.sh (attachment file) to /home/linaro/.node-red/node-moduels/red-contrib-tinkeros-gpio/nrgpio.sh file
then start node-red service again and found asus output node can work properly on Thinker Board 2 
I think your nrgpio.sh file very helpful to make Thinker Board 2 control DO, DI with Node-Red easily.
