<div class="markdown_content"><p>Hi,<br/> I use:<br/> - PI3 &amp; PIFACE<br/> - Version 3.5.12.10 CODESYS and Raspberry PI runtime<br/> - Rasbian Stretch from 11-29-2017<br/> - enable the SPI under raspi-config<br/> - specify the maxspeed to 100000 in the CODESYS Project (PIFace IOdriver exampe)<br/> this works for me! <br/> BR<br/> Edwin</p></div>

<div class="markdown_content"><p>Hi<br/> I have tried it, but it did not work. Even reloading the application. Any additional hint?</p></div>

<div class="markdown_content"><p>Hi,<br/> yes, the workaround is to reduce the SPI maxspeed in<br/> the CODESYS configuration.<br/> BR<br/> Edwin</p> <p><img alt="IMG: SPIMaxSpeed.jpg" rel="nofollow" src="https://forum.codesys.com//download/file.php?id=3533"/></p></div>

<div class="markdown_content"><p>Dear all<br/> SPI master is not working any more after installing the latest raspbian-2017-12-01. It runs perfectly well with previous version (<a class="" href="https://downloads.raspberrypi.org/raspbian/images/raspbian-2017-09-08/" rel="nofollow">https://downloads.raspberrypi.org/raspb ... 017-09-08/</a> kernel 4.9.41-v7+).<br/> It seems that the SPI kernel 4.9.59-v7+ interface has changed in RPi side creating the need for a change in CODESYS run time. Something to do with clock divider, maybe. I tried setting SPI master parameter _dMaxSpeed to several different values, no effect.<br/> I have tested with Piface OI driver, but all hardware using SPI interface would be affected and that is why I would like to 3S personal to take measures.<br/> Thanks<br/> L.P.Laus</p> <p><img alt="IMG: Sem título4.png" rel="nofollow" src="https://forum.codesys.com//download/file.php?id=3532"/></p></div>
