#89592 - Have you accounted for..... Responding to: ???'s previous message |
Have you taken into account that on most of the more "standard" types of 8051's that the ports are "bi-directional" and it is necessary to write a "1" into port output latches for I/O pins that are to be used for input?
If this is news to you then you have more study to do in the tutorials and the "8051 bible" documents from the LINKS section of the WEB site. Michael Karas |
