<div class="markdown_content"><p>Hello,</p> <p>Yes I've enabled the tty, i've used the raspi-config and I've set in interfacing options serial to disable for login as I've seen on other guides. But the hardware port it self is enabled.</p> <p>However I'm using ttyAMA0, is this wrong?</p> <div class="codehilite"><pre><span></span><span class="n">dmesg</span><span class="w"> </span><span

<div class="markdown_content"><p>Hello, I'm working on a project where I want to connect to my Raspberry Pi 3 B+ via RS232. I want to use the on board RX/TX pins.</p> <p>I've made a small program to test it but I keep getting an 5004 Error on my COM.Open function.<br/> I've used some code from a GitHub repo as reference but I'm still getting error's.</p> <p>I've attached a printscreen of the code running with the 5004 error visible.<br/> I've checked around and tried multiple things I've seen from other posts but nothing worked so far.</p> <p>I'm using CodeSys V3.5 SP13 Patch 1<br/> CAA SerialCom Library</p> <p>Thanks in advance.<br/> Jay.</p> <p><img alt="IMG: COM.PNG" rel="nofollow" src="https://forum.codesys.com//download/file.php?id=4157"/></p></div>
