OSError: [Errno 121] Remote I/O error #34
Comments
@chrisb2 sorry to at you but this is important for its use |
Code and circuit look good. Please can you check that the device is visible on the i2c bus with: Just checking but have you enable i2c as described in https://www.raspberrypi-spy.co.uk/2014/11/enabling-the-i2c-interface-on-the-raspberry-pi/. Chris |
I2C is enabled and when running |
Searching in Google it seems the
Things to Try Verify all the wires to the device are good and joints are solid? Are they soldered (dry joints?), or is this a prototype board (dodgy connection?)? |
The leads are about 10cm long, and the circuit diagram is accurate minus the light and 12V battery.
I'm having issues with installing utime so i used |
Maybe try sleep(1). Using a Pi 4B and latest Bullseye and a simple circuit like yours except bulb is a LED and series resistor powered from Pi 5V, I can make a measurement using example.py with busnum=1. I think it most likely the issue is something to do with your circuit, can you try the following to try and eliminate where:

To be clear, the LED does work now, yes, and I am using a separate power source with the ground shared with the pi. |
So you can measure current and voltage with LED circuit? |
The LED lights, but the board gives the same error. |
So I think your ina219 has a problem, I have never seen this simple led circuit fail with my library. The LED is always going to light unless the shunt resistor is dead, the ina219 chip on the breakout is another matter. I think you need to obtain a new breakout. |
Oh alright. I'll resolder another one and try then. Probably later today. |
After soldering a new board and closely inspecting the old one to see the ground pin wasn't even soldered on, it works! Thank you so much. Have a great day/evening what be it. |
As indicated by the title I am getting this error.

Running on a Raspberry Pi 4B 4GB.
Any help would be greatly appreciated, thanks!
