okay, re-explanation.
check the pinout of the chip... notice the DIR pin, which you normally
tie to +? (maybe GROUND, I don't remember) In the walker schematic at
andrew millers walker page (is that the person??? memory loss...) it
says to tie the DIR pin to + (GND?) and the little things will face one
way. release it from + (GND?) and they should face the other way. I
wouldnt be using them both ways... maybe an XOR thing to control the
DIR? my main question was whether both of these would work:
(Normal) ____
|\ / \
-| \0--------| M |----------
| / | |
|/ \____/
(Other) ____
/ \ |\
--------| M |-----------| \
| | | /0-----
\____/ |/
A little clearer??? what I want is to know if the little things work in
series on the OPPOSITE side of the motor... if so why not use the DIR
pin and put it to use!!!
