Raspberry Pi and FTDI USB (or Serial)
My goal: Read my OmniMeter v4 from a Raspberry Pi, either with the FTDI/USB adapter, or the serial converter. I have both, USB would be preferred but either is fine. I have read for hours on this forum, and there's a lot of great information, but I'm not having much success yet. Could anyone point m...
