Its not changing with the direction chosen, and its a dc level switch, logic 0 for fwd, and logic 1 for reverse, and its been running that way for 3, maybe 4 years now, on the pwmgen in a 5i25 with prob-rfx2 firmware in it. Looking at the pwm itself with the halscope, its sort of crazy because there is no feedback to the pid right now so its going crazy. It will run from .1 as pid input at 20revs, or 3000 revs at 98% duty cycle, in the direction chosen by the non working dir signal, when the 5i25 is driving it from prob-rfx2 firmware. I have 5i25_7i76_7i78 firmware in it now since that looks to be pretty close to driving a bob. Right now, I'm thinking thats a bug in the 5i25 firmware in that its only coupling the pwm and ena signals to the other pins, but missing the coupling from direction to gpio.027(now on 5i25.0.p2.07 with this firmware) So I'm going to go study the 2 pin files and see if I can figure out why. Later, probably tomorrow, thanks Andy. -- Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
