Fig5: PLL Motor Control Pin Allocation Configuration

Sample Code：

//Standard DLL Speed control

int E1 = 4;

//M1 Speed Control

int E2 = 7;

//M2 Speed Control

int M1 = 5;

//M1 Direction Control

int M2 = 6;

//M1 Direction Control

///For previous Romeo, please use these pins.

//int E1 = 6;

//M1 Speed Control

//int E2 = 9;

//M2 Speed Control

//int M1 = 7;

//M1 Direction Control

//int M2 = 8;

//M1 Direction Control

//When m1p/m2p is 127, it stops the motor

//when m1p/m2p is 255, it gives the maximum speed for one direction

//When m1p/m2p is 0, it gives the maximum speed for reverse direction

void DriveMotorP(byte m1p, byte m2p)//Drive Motor Power Mode
