Wondering if there are any plans for adding software I2C support to any existing epic modules, or any plans for a hardware I2C module?
Or, maybe the shortest path to I2C would be an arduino or raspi module? Adding externally isn’t that bad, but an Opto22 module would be a tight integration.
I second this recommendation. Specifically, I use allot of Atlas-Scientific stuff, pH, Dissolved Oxygen, Conductivity, ORP, Flow, Temp, CO2, Color, etc. Even their dosing pumps connect via I2C. I use their EZO circuits and isolated carriers w/ I2C support. Good stuff. Once you master communicating with one of their sensors via I2C it’s similar for everything else.
I’m working on a RaspberryPi 4 w/ Rasbian Buster and Node-Red. Trying to implement an I2C flow for these instruments. It’s not just the data logging… it’s also the calibration that you must accomodate.
Anyway, I like the idea of bringing this stuff in to a Process Automation Controller like the Epic.
I’ve been toying with getting one of these I2C to USB adapters. Maybe the quickest way to this is via USB and a hub for multi-components? Anyone here have experience with these adapters?
EPIC (as you probably know) supports USB to serial adapters. I would like to see someone try an I2C adapter and report back. In my mind it would depend on how the device driver loads up, if it emulates a serial device or not.
We have toyed around with Ethernet I2C converters, but found their API to be very clunky.
