The SmartEdge IIOT Gateway is a Raspberry Pi 3 Compute based industrial Linux box. It runs Raspbian with some additions. There's a set of industrial hardware extensions. In this blog I review the isolated CAN port.     Hardware  The gateway has a physical CAN driver. That's a piece of hardware that's not available on the standard Raspberry Pi family.   On a Pi, the CAN protocol itself is implemented in Linux/HW and you have access to the Tx and Rx signals on logic lev ...
The SmartEdge IIOT Gateway is a Raspberry Pi 3 Compute based industrial Linux box. It runs Raspbian with some additions. There's a set of industrial hardware extensions. In this blog I review the isolated industrial I/O.   GPIO Hardware  The SmartEdge IIOT Gateway (from now on: gateway) has two banks of isolated I/O - named DIGIO A and B. All signals are isolated from the Raspberry part via optocouplers. Each bank has 2 inputs and outputs that share a common ground*. The inpu ...
I'm checking if I can use OpenPLC on small Linux devices. The software is known to work on a Raspberry Pi. I'll try it out on that first. I can focus on the functionality instead of installation and dependency resolution. It 'll also give me a chance to measure how much compute resources the application needs.   Open PLC is a combination of 3 modules: a runtime, executes PLC programs you made in  ... ... the editor, where you can write programs in ladder logic and other PLC lan ...
I'm trying to control an Adafruit stepper motor with the high-end timer (NHET) module of a Texas Instruments Hercules microcontroller I got a freebie from TI almost a year ago. An Adafruit stepper motor, a driver board and a Hercules RM57 LaunchPad. The code to run the motor was expected to arrive too (it was an assignment for an internal) but that never materialised. In this blog series I'm trying to program the NHET module so that it sends the right signals to make the stepper step.   ...
