Re: Fastest way to read Analog signal from AIO and store on Revpi

Answered my own question. In PICTORY there is a setting for ADC_DATARATE. Changed to 160 Hz and that did the trick. 1636110598822 18614 1636110598843 18615 1636110598862 18615 1636110598883 13492 1636110598902 18545 1636110598922 18786 1636110598941 18786 1636110598962 15671 1636110598981 18599 1636...

Re: Fastest way to read Analog signal from AIO and store on Revpi

Do you know if I can speed the time the actual analog refreshes? I'm not capturing the constantly changing reading on input 1. Im using your script above with one input as an example and while the loop reads at 20ms the reading from the analog doesn't update at this rate. e.g Time Milliamps 16361090...

Re: Fastest way to read Analog signal from AIO and store on Revpi

Brilliant. Thank you, thats just what I needed. I was making my python too complicated. This will work great.

Fastest way to read Analog signal from AIO and store on Revpi

Hello, I have one Analog signal that I need to read and store as fast as possible. I am using Core 3+ and AIO. I also need to store the reading locally on revpi for a short period ideally in database. I have the Analog signal reading ok using Revpi node in node-red but it doesn't appear to be captur...

Re: MIO and RevPi Data Capture Rate Query

Thank you. It should just be one 4-20 input and 1 digital.

Re: MIO and RevPi Data Capture Rate Query

Thank you for your reply. Wasn't aware the MIO was voltage only. Might be that a dedicated datalogger is what I would need for this project.

Thank you.

MIO and RevPi Data Capture Rate Query

I have a project that will require me logging an analog signal (4-20ma) when a valve is open (Digital signal). I was thinking of using Revpi Core with MIO or Revpi Compact for this job. I would like to use Node Red to capture and send to data to DB on the Revpi itself. My main concern is that the Va...

Thank you for this, was wondering what had caused this. Suddenly appeared after an update. PI nodes now deleted. Thank you.

One set of counters is reset every hour with no issue using the .reset() command. The other 2 counters I want to reset a lot less frequently but we still want...
