<div class="markdown_content"><p>Hello!</p> <p>I'm currently working on a project which have lead to a few headaches, hopefully some kind soul can help me out!</p> <p>I am getting data from a laser which fills up an array once pr 500ms, from spot <span>[0]</span> to [x].<br/> The data needs to be datalogged, but that process uses a trigger which is limited to once pr second.<br/> My question is; how to "move" the value from the array to an variable without it skipping an spot in the array.</p> <p>Open to suggestions!</p> <p>writing to array: <br/> IF R_SLAG_OK THEN<br/> F_FIFO_WRITE(cbData := SIZEOF(Value_Diff), pData := ADR(Value_Diff),<br/> cbBuffer := SIZEOF(arrLaserValueHistory), pBuffer := ADR(arrLaserValueHistory)<br/> ); <br/> END_IF</p> <p>Thank you in advance, have a great day!</p></div>
