Hello,

I looking for a python sample for sparkfun module MAG3110, Does anyone know where i can find an example?
used Pycom Sipy and i can´t get info of sensor using i2c

There is my code for add more info,

Thanks

Code: Select all

start_val = 2590  # 259.0 degrees
i2c = I2C(0, I2C.MASTER, baudrate=100000, pins=('P9', 'P10'))
addr = i2c.scan()
if addr:
    addr = addr[0]
else:
    addr = 0x21  # use default address
    	
class Sensor():
    def __init__(self, i2c, addr):
        self.i2c = i2c
        self.addr = addr
        self.val = 0

    def read(self):
        self.i2c.writeto(addr, bytes([0x41]))  # query for heading
        time.sleep_ms(10)
        # read 2 bytes
        raw_val = self.i2c.readfrom(self.addr, 2)
        # bitshift first byte 8 places to the left
        self.val = raw_val[0] * 2**8 + raw_val[1]
        return self.val

sensor = Sensor(i2c, addr)
other_val = sensor.read()
