Create and use own I2C-Device in Codesys

Hi,

Maybe you have found it yourself allready.

Press Menu (upper left),
Select Drivers, now the Device Drivers page opens.
You can find many open source device drivers which are i2c or SPI based here.

Select I/O Drivers => All the information to start writing your own device driver for i2c / SPI can be found here.

Hope this helps you in the right direction.

I know this is a old (ish) thread, but i've got a similar question,

I've got a sensor that i need to interface with on a machine i'm upgrading.. the thing is it produces a 5 digit BCD output... (which is a load of pins... ) so my plan is to program up a little arduino mega, and then use i2c to send the value into the PLC, (which is an raspberry Pi)

so looking at some of the FB examples of the i2c seems i can just pick the data off the bus,

but having not tested it yet i'm hoping someone has an example.. or give me some guidance..

thanks

Hi Forum,

I have the same problem. I bought the new Pixtend V2. Old I²C examples doesn't run properly in the new Codesys Software. I can't see the source code, only when fail. A double click on the error opens the code. The librarys gets many errors.

Why is the source hidden? Some of us need only a small example for I²C-Bus i.e. step by step create a device.

Anyone confirm whit the new Pixtend V2?

Hi!
Currently I only have some draft documentation for SPI. If you have some time left, I can provide you the first I2C draft as soon as it is available (via E-Mail).
If not, I can try to assist you in the creation of your specific driver.

I would like to create a driver for a INA226 device, would you be able to give me some quick guidance on how I create the library? I have seemed to figure out how to Add
an existing Library, but how would I go about actually creating a new one?

Hey Ingo, you can email me and I can go from there for the time being. my email is simple, its my username here then gmail. Thanks for your help. I found a bit of documentation in the manual that I think would get me by, through lots of trial and error.

On another note, my Raspberry Pi Zero just fried, I will need to get another board, do i have any luck getting the license on the new board that you or anyone here knows of?

I'm not sure how to pm but Ingo Hornberger, can you send me a message? I'd like to create a driver for the raspberry pi.

Hi,

no template this far, but I hope that we have that in the future. But I can recommend you to have a look into the existing driver libraries. Those are provided in source, in the hope that they are usefull.

Everyone seriously interested in driver development on the Pi is welcome to leave me a PM.

BR,
Ingo
