<div class="markdown_content"><p><em>Originally created by:</em> dosnova</p> <p>Problem solved. Some raspberry touchscreens have to be connected to the same equipontential 0V line used by raspberry. Floating 0V induces errors in touch events.</p></div>

<div class="markdown_content"><p><em>Originally created by:</em> dosnova</p> <p>Dear All,</p> <p>I'm trying to use touch events such as OnMouseDown or OnMouseUp associated to a button in a WebVisu screen. Those events have no effect. </p> <p>Is this problem related to CodeSys or is a Raspbian touch driver related issue?</p> <p>Thanks in advance.</p></div>
