No, I don't.  In your case, since you are sharing one of the PWM lines with
the programmer, you do want to pull the enable line down while programming.

Thank you Larry. Those articles give me some good insight.  Now I feel
just confident enough to be a danger to my little robot friend :-)  I
think I'm going to go right in and try Locked Antiphase.  Once I get it
working in my own robot, I may have to ask a few questions since hopefully
by then I'll understand enough to form a lucid question.

I saw in the articles how you described the current consumed at 50%
dutycycle (motor stopped).  Is this ok? Or should the enable pin be
disabled when you want to idle?

One additional question, do you use pull down resistors on any of the
motor driver pins?  My gut is saying to at least pull the enable pins down
(disable) to ensure the robot isn't fidgeting during I/O initialization
and also during the really fast boot time for the tiny26.


You've given me lots of good info today, both on this thread and another
(magic ways to access pin values in C programs).  Thank you.

I'm going to give PWM a try. I've been combing over the ATtiny26 datasheet
all day (picture Spaceballs when they comb the desert) to try to see if I
can get it working on my own.  But, dont be surprised if I fire a few PWM
setup questions to the group :-)
