Title: Very newbie question:
Post by: Techman09 on November 09, 2008, 02:48:59 PM

How do I set a pin to Hi or Low when outputting to a motor controller or H-bridge???
I am looking for a way to define my drive functions for 4WD inside of the society of robot
"hardware.c" function lists.

I have searched the library documents, but I need some help here.
I am trying to figure out how to make the I/O lines either hi or low.

Thanks.

Using C, trying to alter the files on this site for controlling motors instead of servos.
and the Axon.

something like maybe

PORTE6 = 00000001

or

PORTE6= 1

i amthe code to accomplish this in "C". It seems like this would be so easy to come by, but for some reason, I cannot find anything to manipulate the high or low value for an I/O pin.

Include SoR_Utils.h and then use something like this,
PORT_ON(PORTD, 7);
and
PORT_OFF(PORTD, 7);
