<div class="markdown_content"><p>The instructions on the canberry website are not fully correct certainly for Stretch:</p> <p><a class="" href="https://www.industrialberry.com/?s=codesys&amp;submit=Search" rel="nofollow">https://www.industrialberry.com/?s=codesys&amp;submit=Search</a></p> <p>3 things need to be done: Line 3 one doesn't uncomment but one needs to insert the complete lines (also note that the word overlay is removed after the mcp2525-can0 and -can1</p> <p>Insert the line dtoverlay=mcp2515-can0,oscillator=16000000,interrupt=22 for CanBerryNormal, Isolated and CanBerryDual<br/> Insert the line dtoverlay=mcp2515-can1,oscillator=16000000,interrupt=25 only for CanBerryDual</p> <p>After line 8, you must copy ALL the files in canberry-codesys folder (not the folder) to /home/pi</p> <p>Also I2C needs to be activated even if you do not intend to use the RTC.</p> <p>Once done it works as expected!</p> <p><img alt="IMG: Capture8.PNG" rel="nofollow" src="https://forum.codesys.com//download/file.php?id=4167"/></p></div>

<div class="markdown_content"><p>Seem to have got one stage furtehr. I wasn't using the RTC so did not enable I2C as the Can only uses SPI.</p> <p>It is now working after enabling I2C.</p></div>
