RuntimeError: MPU6500 not found in I2C bus.

See original GitHub issue

Hi, I’ve wired the sensor to nodemcu esp8266, however the library si giving me the following error:

Traceback (most recent call last): File "<stdin>", line 6, in <module> File "mpu9250.py", line 39, in __init__ File "mpu6500.py", line 103, in __init__ RuntimeError: MPU6500 not found in I2C bus.

Wiring: CLK->pin D1, SDA->pin D2.

i2c scanner shows:

Scan i2c bus… i2c devices found: 1 Decimal address: 104 | Hex address: 0x68

I’m using MicroPython v1.12 on 2019-12-20

What could be wrong?

You should be able to use the standalone MPU6500 witch something like following:

from machine import I2C, Pin
from mpu6500 import MPU6500

i2c = I2C(scl=Pin(22), sda=Pin(21))
sensor = MPU6500(i2c)

print("MPU6500 id: " + hex(sensor.whoami))

MP65 suggests the chip is the standalone MPU6500. Also the WHOAMI value suggests it is the standalone MPU6500 and not the MPU9250 SIP. In other words it does not include the magnetometer.

I have only been testing with MPU9250 which was why I did not catch earlier that the standalone accelerometer has different WHOAMI value. Will commit a fix soon. Thanks for the heads up!
