#159992 - circuit
Responding to: ???'s previous message
Yes, after moving the motor I set the port to 255, which is the way I got the motor free, setting to zero the coils still powered.

You mean, bring the coils "common" to ground? How can I do this? Can I make using the 2003?

I using this same circuit, except is only one motor, the CI which is 2003 (no 2803), the pins is a bit different, but I already verified the pinout at datasheet and fixed (8 and 9 for - and +)... the control inputs are connected to P2




Thanks.
