pololu dual serial motor controller

Henrymou

I am using the pololu dual serial motor controller from parallax w/ a basic stamp 2
in the following program, only 1 motor should turn
but in reality both motors are stuttering

' {$STAMP BS2}
' {$PBASIC 2.5}
speed VAR Byte
DO
HIGH 14
LOW 15
HIGH 15
PAUSE 100
speed = 127
SEROUT 14,84,[noparse][[/noparse]$80, 0, 0,speed]
PAUSE 20
LOOP

has the motor controller fried?
please help

Hmmmmm......

Well this happened to me also because the motor controller overheated.

However... In your code I would try placing:

HIGH 14
LOW 15
HIGH 15
PAUSE 100
speed = 127

before the Do....Loop.

Then you would not be restarting the pololu motor controller·during every loop cycle.

well, It's controlling two 1.5V motors at a 5v power supply.
I did this and it worked THANKS!
I think that because the Stamp is sending serial data that It was getting confused while being programmed.
