I have rotation bug in ServoBlaster..
I'm using these values:
- 1500us : Idle
- 1530us : Pulse left
- 1480us : Pulse right
For example :
echo 1=1500us > /dev/servoblaster.
BUT, my problem is the (continuous) servo which rotates itself sometimes.. I mean, I make it to rotate to the right, I stop (idle), rotate to the left, stop (wait some seconds), and sometimes it will begin to rotate again itself and don't stop until I give it pulse left or pulse right value (it will not stop anymore with idle pulse)..
Do you have an idea ?
EDIT: I'm using an external battery for the motor (5V 2.1A). The battery GND pin is not connected to the RPi GND pin (otherwise, the motor is crazy sometimes).
