Having trouble reading MPU6050 sensor via I²C on Pine64

[congb]

Make sure you're using a reliable library like smbus2 or Adafruit_CircuitPython_MPU6050.
Here's a simple example using smbus2:

Code:

import smbus2
import time

bus = smbus2.SMBus(1)
address = 0x68

# Wake up MPU6050
bus.write_byte_data(address, 0x6B, 0)

def read_word(adr):
    high = bus.read_byte_data(address, adr)
    low = bus.read_byte_data(address, adr+1)
    val = (high << 8) + low
    return val

def read_word_2c(adr):
    val = read_word(adr)
    if (val >= 0x8000):
        return -((65535 - val) + 1)
    else:
        return val

while True:
    accel_x = read_word_2c(0x3B)
    print("Accel X: ", accel_x)
    time.sleep(0.5)
