Wipy 2.0 and ADS1115

[MaximoTuc]

Hi All, I've spent almost a day getting this simple AD to work.- Hopefully you will find it before it is too late. See changes below.-

class ADS1115:
def init(self, i2c, address=0x49, gain=0):
# Modified to work in Wipy2.0
self.i2c = i2c
self.address = address
self.gain = gain # 0 --> 2/3 6.144V

def _write_register(self, register, value):
    # Modified to work in Wipy2.0
    data = ustruct.pack('>BH', register, value)
    self.i2c.writeto(self.address, data)

def _read_register(self, register):
    # Modified to work in Wipy2.0
    data = self.i2c.readfrom_mem(self.address, register, 2 )
    return ustruct.unpack('>h', data)[0]
