P1.6 on MCB 900 - tank_cmdr_m1a1 - Apr 5 15:46:00 2005
I am having a problem using P1.6 as an output on the Keil MCB900
board. The port pin seems to be stuck or pulled low. I've confirmd
that my code is setting it as a push-pull, and I find nothing
connected to P1.6 on the MCB900 schematic.
Do any experts out there have some ideas of what's causing my problem?
I've taken my code and swapped P2.5 in place of P1.6, and everything
works fine. It seems like the problem has to be in the board/hardware.
Does the MCB900 have programming code/firmware on it that inhibits the
use of P1.6? Thanks
