About a year ago I had the bright idea of using a PIC and a VDIP1 to transfer file to a Burny 2.5 CNC controller. I could never get it working properly and gave up.

The Burny was never happy with the data being sent to it. My simulation software worked fine. I wonder if what newbie is seeing was the problem with the Burny?

Somehow the VDIP is sending "ghost" info??
