    Has anyone tried to use the BerryIMU on Raspberry Pi 5?.  My unit worked on a RPi 4b, but won’t do anything with a new RPi5.

    Yes, it does work on the Pi5

    Do you see anything when you do  “i2cdetect -y 1”

    I get the following error message

    $ i2cdetect -y 1
    Error: Could not open file /dev/i2c-1' or/dev/i2c/1′: No such file or directory

    This is on a fresh install of 64bit RPi Bookworm. The BerryIMU is attached to the Pi board directly though a header, and this works without issues on a 4b,  If I try to run cat or screen (which seems to  install correctly) i just get no response.

    That error means that i2c is not enabled on the Pi.  Did you do this? https://ozzmaker.com/i2c/

    I have enabled the i2C following your script, and now get a table output identical to the one in the example. There is still no output from cat or screen, (just a block cursor), although the “fix” led on the BerryIMU is flashing away happily.

    sorry, I’m getting confused. If I enable the I2C do I also need to close the jumpers J10 and J11 on the back of the board?. If so how did the board work with the Pi4, where it works fine with these open?

    Are you using a BerryIMU or a BerryGPS-IMU(which includes a GPS)?

    If you are using a BerryGPS-IMU, is it sitting on top of the Raspberry Pi?

    Its marked BerryGPS-IMU-4, and it is sitting on the Pi connected via a 10-pin header

    I’ve been using the “BerryGPS setup guide for Raspberry pi” to try to get the data.

    I’ve also realised that this should have been posted in the BerryGPS part of the forum, to avoid confusion. Sorry.
