For development we are using CodeSys (V2.33.5) We want to receive CAN-data with the Peak-CAN IPEH 2022 that we connect on a USB port.

We know the Codesys support our CAN-Interfaces, but we could not give support on third party Software - sorry.

For more information see the UniPi Neuron compatibility section on our CODESYS SW help section.

As a result, your viewing experience will be diminished, and you may not be able to execute some actions.

The Evok API makes all the IOs available over different kind of web-based APIs such as REST, Websockets and so on.

When I delete the UniPiAI I2C module and instead of that insert the MCP3424, I do get data, but it doesnt seem correct.

Even if I leave the Unipi AI module and then use the I2Cmaster.read(1668, ADR(baReadBufferV), 4); command, it shows data in the buffers that varies when the input voltage is adjusted.

Instead, they are accessible via local ModbusTCP server (you can see the Modbus Registers Map).

The package also installs a new application template so that in one step you can create a new UniPi application with all devices installed ( you will just need to add the expansion module).

Codesys Forum Drivers To CODESYS

CODESYS for UniPi is adding device drivers to CODESYS for raspberry pi.

There is a large active forum of users on the CODESYS forums.

I suggest that for general CODESYS questions you will find answers to most of your questions already posted there.

UniPi had removed the UniPian image and so I removed UniPi Neuron for CODESYS from the CODESYS store.

I have since been working with UniPi and a new Image for UniPian was released today.

The UniPian image will work with CODESYS 3.5.12.x and the release UniPi Neuron for CODESYS.

There is also a UniPi Neuron library included in the package which makes it easier to handle the data types which span more than one register.

Im sorry to say but there was a compatibility issue with the version of UniPian that you are using.

If you use the version referenced in the datasheet then you should see no problem.

UniPi have released a new Version of UniPian V1.9 today that I believe resolves the issue.

Codesys Forum How To Use Groups

There are instructions in the data sheet on how to use groups 2 and 3.

As a summary getting the IO to work with Group1 was fairly involved, and given that it is identical across all Neuron devices a function block instance is created and the mappings from registers is done automatically.

For groups 2 and 3 you will need to map the IO using standard CODESYS features.

To make this simpler, all of the Registers and Coils for these groups are named, there are also function blocks provided that will assist with converting between registers and larger data types.

It looks that the issue I have is related to the bootconfig.txt file (dtoverlayw1-gpio).

Is this OK.

As per my knowledge many times you would not use the power from the USB-UART converter.

The TTL signals come in different flavors.

V, 3.3V and 1.7V being common.

This is all the more reason why not to use the power from the UART adapter.

You will need to use the UniPian image for CODESYS, but you will also need to buy the CODESYS for Neuron plugin.
