Hi everyone, I have a Raspberry Pi 2 Model B running an Ignition Edge Gateway. Everything works smoothly. Is there anyway of accessing the GPIO’s on the Raspberry Pi from within the Ignition Edge Designer? ---

Hmm. Sounds like a driver is needed. Doesn’t look too hard. I’ll add this to my to-do list. ---

My abandoned RPi OPC UA server project can access them: [https://github.com/kevinherron/pi-server](https://github.com/kevinherron/pi-server) Rumor has it the server might actually work again soon… ---

Another way of doing it if you cant access the GPIO is a python script to send the GPIO status to a DB and access that in ignition. ---

@pturmel - cool! Let me know when you have something. @Kevin.Herron - I have tried yours already without success. I have the latest version of Java installed however it still crashes with an error something like this: “JVM failed to launch” and it also states that it expected another BCMxxxx than was found on the RPi. I thought it might be some hard problems due to compatibility now when the server is a bit outdated. @craigb - yeah, that could definitely be the workaround this problem. I might just do that to get on with things. Thanks for the inputs all of you. 👍 ---

You should give Node-Red a try, It can allow you to interact with the GPIO and provide access via OPC-UA, MQTT Sparkplug or Modbus. I have a few Pis with various IO boards on my bench, ---

@Kyle_Chase - Awesome, I will give it a try! Thanks!
