SDAFE - Software Defined Analog Front End
Industrial Automation relies on reading field variables that are still predominantly analog values like 4-20 mA, 1 to 5 VDC, and 0 to 10 VDC. These...
Raspberry Pi and Graphic Display Interfaces
Here is a project that uses our 128x64 Graphic Display / User Interface for the RPI 3.
The user interface module has a 1.4" LCD, three pushbuttons...
RPi 3, Pi-SPi-RS485 and Gas Sensors
The brand new Pi-SPi-RS485 Interface has just arrived and I had to take it for a spin with some of our products. Here is a pic of my test setup:
