Detailed Description

DRV8830 class.

This is a driver code for the DRV8830 H-Bridge Voltage-Controlled Motor Driver. http://www.ti.com/product/drv8830

 #include "mbed.h"
 #include "DRV8830.h"

 // I2C Communication
 DRV8830 motor(PinName p_sda, PinName p_scl, addr);
 // If you connected I2C line not only this device but also other devices,
 //     you need to declare following method.
 I2C     i2c(PinName p_sda, PinName p_scl);
 DRV8830 motor(I2C& p_i2c, addr);
 
 int main() {
 uint8_t status;
    
     //  Speed control
     motor.speed(0.5);    // CW
     motor.speed(-0.5);   // CCW
     motor.speed(0.0);    // Stop(FREE)
     //  Check error and reset
     status = motor.status();
     if (status & DRV8830_F_FAULT){
        motor.reset();
