Acceptable values for m4_ms are: 0 -- Full Step 1 -- 1/2 Step 2 -- 1/4 Step 3 -- 1/8 Step void fn_TurnCon1(long m1_StepsVal, long m2_StepsVal) Rotates motors 1 and 2, the two motors connected to controller 1. Motor 1 will rotate [m1_StepsVal] steps, and Motor 2 will rotate [m2_StepsVal] steps. Accepted values for m1_StepsVal and m2_StepsVal are from 0 to 2147483647, inclusive. void fn_TurnCon2(long m3_StepsVal, long m4_StepsVal) Rotates motors 3 and 4, the two motors connected to controller 2.

Accepted values for m3_StepsVal and m4_StepsVal are from 0 to 2147483647, inclusive. void StopRotation() Sets the number of steps for all motors to 0, stopping the rotation of all motors. void StopRotationM1() Sets the number of steps for Motor 1 to 0, stopping the rotation of Motor 1. void StopRotationM2() Sets the number of steps for Motor 2 to 0, stopping the rotation of Motor 2. void StopRotationM3() Sets the number of steps for Motor 3 to 0, stopping the rotation of Motor 3. void StopRotationM4() Sets the number of steps for Motor 4 to 0, stopping the rotation of Motor 4. DLLVersion() Returns the version number of the StepperControl.dll file. __int64 GetSystemCounter() Returns the value of the PC's internal system clock. The units of this value are clock cycles since the last overflow. This value is used with the system clock frequency to time events with high resolution. __int64 GetSystemFrequency() Returns the value of the PC's internal system clock's frequency, in number of cycles per second. To get the time elapsed, divide the number of cycles by the frequency. __int64 SystemDelay() Calls the C function QueryPerformanceCounter twice and returns the difference between the first call and the second. This function then returns the number of system clock cycles that elapsed between the two calls. void OutStepDLL( short PortAddress, short Data) Writes the value of Data to the port at address PortAddress. See set_controller1 for valid values for PortAddress. void InStepDLL( short PortAddress) Reads the value of the data in the port at address PortAddress. See set_controller1 for valid values for PortAddress.
