I've tried the tutorial but the tut uses the TW and it has its control lines on a different port. Hal Albach has commented on your use of a single port: http://www.8052.com/forum/read.phtml?id=147287 Have you heeded his observations? Jon Ledbetter also referred to this: http://www.8052.com/forum/read.phtml?id=147320 Have you done as Jon suggested, and run this in a Simulator? |
