i have bought a brushless motor from robokit and tried to run it with at89s52.. but i am not able to run it. here is image of motor i bought at the input power pin, i have applied a 12 V dc. at the other three pins i have applied the control pulse, but it is not working. here is the programing code for the control pins i used #include <regx51.h> sbit i1=P2^0; //for control pin 1 sbit i2=P2^1; //for control pin 2 sbit i3=P2^2; //for control pin 3 void MSDelay(unsigned int); void main() { P2=0x00; while(1) { i1=0x01; MSDelay(40); i2=0x01; MSDelay(40); i3=0x01; MSDelay(40); i1=0x00; MSDelay(40); i2=0x00; MSDelay(40); i3=0x00; MSDelay(40); } } void MSDelay(unsigned int a) { unsigned int i,j; for (i=0;i<a;i++) for (j=0;j<1275;j++); } resulting in output as attached file.. whats wrong here...
