hbridge_0.init_i2c_address(0x20)- Initializes Unit and sets the I2C address
print(hbridge_0.get_adc_value(0, 8))- Get voltage resolution
print(hbridge_0.get_vin_current())- Get voltage (A, Float)
print(hbridge_0.get_device_status(0xFE))- Get the Unit version
print(hbridge_0.get_driver_config(4))- Obtain configuration information
