Does anyone have experience with GPIO use in PLC RADXDA zero hardware?
The standard GPIO nodes for Raspberry pi understandably do not work.
Raspberry pi is not available, Radxda can be bought, it even has higher computing power for MQTT and Grafana.
Could someone advise how to modify the node for simple use of IO pins (input, output, PWM output)?
The radxda has a different mcu and gpio . The nodes for raspberry pi is written in c++ for the hardware of rpi. You must rewrite the gpio driver for radxda and this isn't easy. An other way is to write the gpio with sysfs using javascript. There is a radxda forum. You can ask there for help.
Thank you, I will post the procedure as soon as I solve it.
