From what I could figure out from the literature on the HB, the motor
controller circuit is controlled by Port B on the 6811. With a little
tinkerin last nite I was trying to set/reset some of the pins poking values
into $1004 (Got this from "An Introduction to the 6811" by Fred. I assumed
that the miniboard used the same port for motor control that the HB does).
It didn't seem to work. No changes at the l293 inputs. So...... I got to
wonderin..... Are the PWM routines overriding my changes. If so, is there
a way to disable the PWM so that I could use those outputs.
For what I'm trying to do, I don't use the motor controllers and I don't
want to give up any of the other input capability.
Thanks
