# Get I2C bus
bus = smbus.SMBus(1)

# MPU-6000 address, 0x68(104)
# Select gyroscope configuration register, 0x1B(27)
# 0x18(24) Full scale range = 2000 dps
bus.write_byte_data(0x68, 0x1B, 0x18)
# MPU-6000 address, 0x68(104)
# Select accelerometer configuration register, 0x1C(28)
# 0x18(24) Full scale range = +/-16g
bus.write_byte_data(0x68, 0x1C, 0x18)

# MPU-6000 address, 0x68(104)
# Select power management register1, 0x6B(107)
# 0x01(01) PLL with xGyro reference
bus.write_byte_data(0x68, 0x6B, 0x0

Above are the code.
Its in +-16g but and according to the datasheet http://https://www.invensense.com/wp...ister-Map1.pdf page 15, its AFS_SEL. So i just simply replace the '0x18' into AFS_SEL = 0 and replace '0x18' into FS_SEL = 0 for both accelerometer and gyro?
