To start things off, I'm not a programmer so this is a 100% learning curve for me.
Project: To capture O2 readings from an analyzer that can export this information via a serial port. Then display the latest reading and create a graph to show trending over lets say 5 hours.
I see tons of projects were people are getting temperature readings and imputing this data into a RRDTool database and graphing the data. I'm sure I can modify the code to do what I'm looking to accomplish.
My issue is, I don't see any examples of how to capture the data that would be coming off a serial port. Could anybody out there help a non programmer guy out?
Thank you Mark
In the discovery mode right now. Surfed / googled RRDTool and serial ports unable to find the information I'm looking for.
