<div class="markdown_content"><p>Thank you for your answer.<br/> I would use Raspberry for a hobby application, on my (very short) free time.<br/> I'd like To program It by Codesys (instead of Phyton or something else) because I'm able to program plc's...so my idea is: ''I spend 60 euro (vat included) for Codesys  Runtime licence in order to avoid wasting time to learn...make test....experiment...etc.</p> <p>The answer to your question is yes...I'm not able also with correct  instructions...or probably I would be able after a lot of time...and after that I would spend 60 euro for runtime...</p> <p>For the same chip I know the Fab work...I installed It...but Codesys gives an error when I add the device and It is build for temperature sensor...I just need to read a voltage value with high resolution...</p></div>

<div class="markdown_content"><p>Hello!<br/> When you say you can't create it, do you mean you found the documentation for creating I2C devices and weren't able to follow?<br/> If yes, I would like to fix the documentation so it is easier for you and others to follow. So where are you stuck?<br/> If not, then just follow the documentation here, and let us know if you get stuck.<br/> <a class="" href="https://forge.codesys.com/drv/io-drivers/doc/I2C/">https://forge.codesys.com/drv/io-drivers/doc/I2C/</a> m </p></div>

<div class="markdown_content"><p>Hello,<br/> I need to menage an I2C peripheral not present on device libraries : MCP3421 (adc 1ch 18 bit).<br/> I'm not able to create it <br/> Is there a simple way to read/write configuration or data bytes (according to MCP3421 data sheet) by step by step ST instructions, without creating the device?<br/> something like this:<br/> 1) set the device address<br/> 2) set number of bytes to write<br/> 3) write data bytes<br/> 4) set number of bytes to read<br/> 5) read data</p> <p>Can you help me?<br/> Thank you!</p></div>
