readMotorSpeed(id)

Read DC Motor speed

Parameter

Parameters	Type	Description
id	unsigned char	ID number to be controlled, range 0 ~ 18

Return Values

Parameters	Type	Description
number	int	Returns the motor speed, range -140 ~ 140 r / min. The value read is negative for counterclockwise rotation and positive for clockwise rotation

Example

Use uKit Explore v2 board to control the DC Motor ID-1 to rotate clockwise with constant speed of 80 rpm all the time. Then read and print the motor speed every 400ms.

#include "uKitExplore2.h"
void setup() {    
    Initialization();    
    setMotorTurnAdj(1,80,0xffff);
}

void loop() {    
    Serial.println(readMotorSpeed(1));    
    delay(400);
}

Use the uKit Explore v2 board to control DC Motor ID-1 to start rotate counterclockwise at a constant speed of -80. Add the speed every 200ms until a clockwise speed of 80 and print the speed every time.

#include "uKitExplore2.h"
int Angle=-80;
void setup() {    
    Initialization();
}

void loop() {    
    Angle++;    
    Serial.println(readMotorSpeed(1));    
    setMotorTurnAdj(1,Angle,0xffff);	     
    delay(200);    
    if(Angle>=80){	
        Angle=80;    
    }
}
