// This program tests how many clock cycles it takes to drive the motor // one revolution. in this case it takes 400 clocks. // i am using a circuit built around a STK672-330 with attached stepper. #include "mbed.h" DigitalOut enable(5); DigitalOut direction(6); DigitalOut clk(7); int i = 0; int main () { enable = 1; direction = 1; i = 0; while (i != 40000) { // run the motor 100 revolutions, 40 seconds. clk = 1; wait_us(500); clk = 0; wait_us(500); i += 1; } enable = 0; }
