OSError: [Errno 5] EIO #25

Closed project2501x closed 2 years ago

project2501x commented 2 years ago

Hi, I'm running into the following error and I can't figure out for the life of me how to resolve it.

Traceback (most recent call last): File "", line 25, in File "mpu9250.py", line 45, in init File "mpu6500.py", line 97, in init File "mpu6500.py", line 149, in whoami File "mpu6500.py", line 181, in _register_char OSError: [Errno 5] EIO

Could anyone shed some light on the underlying problem here? It seems others with similar problems were able to resolve it via re-inspecting and connecting the board and sensors but I'm having no such luck. Thanks.

Can you see the devices if you do a ì2c.scan()

project2501x commented 2 years ago

Apologies, I could've specified that I do see a device at dec 104, hexa 0x68.

I've resolved this by blanking my main.py script.

My thinking is that main.py, which contained code pertaining to a different sensor, was being executed upon powering the Pico up by connecting it to my PC / Thonny. The code was initialising an object relating to that other sensor and in the process, possibly assigning a different constant value to the WHOAMI register or to a relevant address. I presently lack the understanding to investigate further but will persist to better grasp the error.

Thank you for your prompt response Tuupola, and this great library.
