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 ...
