MPU6050 not connecting with Thonny or VSCode

[JBelmont72]

I'm hoping someone can offer some insight. I have made numerous attempts to connect to my Pico a MPU6050(accepts p to 6 vollts-tried both 3.3 and 5 V)I have changed the chip address in the imu.py library to reflect mine. I get this persistent error( I thought I addressed the 'chip_id' in line 158 by changing the i2c address to mine, and the libraries are recognized in the REPL, etc.) :
I2C SCANNER
i2c devices found: 1
I2C hexadecimal address: 0x68
Traceback (most recent call last):
File "", line 19, in
File "/lib/imu.py", line 105, in init
File "/lib/imu.py", line 158, in chip_id
MPUException: I2C failure when communicating with IMU

this is the simplified program I am trying to run:
from imu import MPU6050
from machine import I2C,Pin
import time

i2c=I2C( 0,sda=Pin(16), scl=Pin(17), freq=400000)

print('I2C SCANNER')
devices = i2c.scan()

if len(devices) == 0:
print("No i2c device !")
else:
print('i2c devices found:', len(devices))

for device in devices:
print("I2C hexadecimal address: ", hex(device))

time.sleep(.2)
mpu = MPU6050(i2c)

while True:
xAccel=round(mpu.accel.x,1)
yAccel=round(mpu.accel.y,1)
print('x: ',xAccel,' G ', 'y: ',yAccel,' G')
time.sleep(.1)
Using Thonny as well as VS code with micro-pico ( I tried commenting out the body of the def chip_id and setting a fixed id without success(just gave a different error- possibly I flubbed that effort)

What library are you using? 0x68 is pretty much the standard address for these devices.

Does you board have pull-up resistors?

Please don't forget to post code between triple backticks (see the Welcome message for details) so we can read it

The driver is evidently this one. To throw the MPUException at line 158 the device has been recognised in an I2C scan, but is failing to communicate when reading the chip ID register. There are two possibilities:

1. An electrical problem making I2C communication unreliable As @scruss suggests, check that you have pullup resistors on both lines.
2. The chip is a Chinese clone. These exist, and don't always work as well as an InvenSense chip.

See (for example) this thread.

Thank you for your help. Yes, I think my MPU6050 s are incompatible. I’m obtaining more from a more reliable source.
