Joe,
great article, I did use that information...
The weird thing is that the P2.3 line does not switch at all....
When I switch on the MCB900, the P2.3 line becomes 3V3 and stays 3V3....
How should the signal look like? Sometimes when I switch on the MCB900 I see that P2.3 becomes 3V3, drops for a few uSec, and then stays 3V3.......It drops just once...
The reason I use a MCB900 is that I use it for more things... ISP for example.
