Re: Delay on DIO output when enabling AIO input

Hi Nicolai, thanks for your quick response! I actually just discovered (RTFM) that the workaround via piTest is also valid for reading input by using the -1 flag... Stumbled over the cyclic reading before. This solves my problem acceptably. If you would still look into why the revpi-nodes don't seem...

Hi Johannes, thank you for your reply. I had already found the answer you have linked and reducing the number of flows or splitting input and output to different flows did not solve my problem. I have also tried to reach the people working on the node-red-revpi nodes but that repository has been ina...

EDIT: Delay on DIO output when enabling AIO input

I have a workaround using a custom 'exec' node using piTest to set the output pins. For now this works. Is there a reason not to hook up 20 of those and sending them payload at a high rate? Or rather what am I missing when not using the 'node-red-contrib-revpi-nodes'? [ { "id": "edf09...

Delay on DIO output when enabling AIO input

Hi :) I am using a RevolutionPi Core 3+ connected to a DIO and two AIOs. The flow I am running is attached below. What I am trying to accomplish is the following: 1. Read input from AIO/DIO at a regular rate >1Hz. I did that with single revpi-input nodes and a trigger before but figured that might b...
