hi all
i connected a servo to the digital 9 port, downloaded the servo.icb and
servo.c files. from the command line i can control the servo. but then i
wrote the following very simple code, and it doesnt work. can anyone spot
the problem.
void main()
{
servo_on(); /* on servo */
servo(3800); /* full left turn */
servo_off(); /* off servo */
fd(0); /* motor 0 on */
sleep(2.0); /* for 2 secs */
servo_on(); /* on servo */
servo(2500); /* mid position */
servo_off();
}
many thanks
m fazal
