Hello everyone,

I ran into a problem, i'm trying to use a pyboard to record datas of both an gyro-accelerometer (on I2C 1) and a barometer (on I2C 2).
So i made a basic code that get all datas and store them in a file on the sd card... The thing is the file always get corrupted.

So as we all do, i tried removing parts of the code to see what specificaly was causing the problem and it seems that it's the barometer, if i comment out EVERYTHING linked to I2C 2 the file is ok...

So, is it impossible to use both an sd card and I2C 2 at the same time? And if not, what could be causing the problem?

Regards, Timon

Without the code, how can we tell what's going wrong?

If you have the SD card mounted as USB storage on your computer, that can cause corruption and is not recommended.

Definitely possible.

Need to see your code. Please post to GitHub Discussions.
