I2C Motor Driver (TB6612FNG) and DC fan error

Products & Technology Grove
#1

I running the following code with Seeeduino Cortex M0, DC fan and Grove - I2C Motor Driver (TB6612FNG) but I get error ,any idea why?

Code:

#include "Grove_Motor_Driver_TB6612FNG.h"
#include <Wire.h>

MotorDriver motor;

void setup()
{
    // join I2C bus (I2Cdev library doesn't do this automatically)
    Wire.begin();
    Serial.begin(9600);
    motor.init();
}

void loop()
{
    // drive 2 dc motors at speed=255, clockwise
    Serial.println("run at speed=255");
    motor.dcMotorRun(MOTOR_CHA, 255);
    delay(1000);
     
}

Since the development board you selected is the Seeeduino Cortex M0, you need to select Seeeduino Zero in arduino.
May I ask what development board you choose in arduino?
Did you choose the right type of development board?

#3

I used Seeeduino Cortex-M0+ and selected Seeeduino Zero in arduino

#4

Perhaps you should try reinstalling the Grove_Motor_Driver_TB6612FNG library.

#5

Different development boards are not compatible.

#6

It would be great if it will be noted with which boards it is compatible

#7

Since the development board you selected is the Seeeduino Cortex M0, you need to select Seeeduino Zero in arduino. There is nothing wrong with the development board you have chosen.

Because you have a Grove_-Motor_Driver_TB6612FNG library error. Have you updated or re-downloaded your library? I used seeeduino zero and downloaded the Grove-_Motor_Driver_TB6612FNG library, which was able to compile successfully
