Delay time is required and stpper would not move when the pulses are too fast. Each winding consume nearly 700mA and  Under half stepping it is about 1400mA. I test with 7805 1A regulator. //stepper test void main()      {    OSCCON=0xff;   //osc configuration for max speed of internal                              osc      TRISA=0;           for(;;)              {               // 8 steps for helf stepping               // 4 steps for full stepping                             PORTA=0x0E; //1110               delay_ms(5);           //    PORTA=0x0C; //1100     ...
