I want to use Unipi with codesys, wish library to use for 8 relay (MCP23008 port expander)?
I am hoping for the same thing. It shouldn't be impossible to use some of the similar drivers and adapt it to unipi-the-universal-raspberry-pi-add-on-board.
I have just released a package of drivers for UniPi in the CODESYS store available for free download - See http://store.codesys.com/codesys-for-unipi.html
CODESYS for UniPi 18.104.22.168 is now available for free from the CODESYS store.
This has full support for the UniPi 1.1 board, and the EMO-1W8R and EMO-4R4DI expansion modules (The SSR versions should also work using the same drivers.
is there a chance to get your package somehow?
It is not available in the Store and nowhere in google search ... :/
Bad news for you @kaif
Until recently, CODESYS was developed and supported by third-party developers. However, the third-party discontinued the product and CODESYS for Unipi controllers is no longer available. For Unipi 1.1 and Unipi Axon it is still possible, but very difficult to use CODESYS.
A possibility exists for Unipi Neuron users through using a clean OS Debian image.
To run CODESYS you need to purchase and download the CODESYS for Raspberry Pi installer package.
The next step is to set up a Modbus TCP server on the PLC, allowing CODESYS to communicate with I/Os of the controller.
Of course the Neuron is also being discontinued and may not be available.
