Sorry , I just noticed that you got the wdt issue when writing to i2c in a loop (I hadn't read it as 'just' writing to i2c in a loop at the beginning)
That make it even stranger

Hi Martin
That make it even stranger
Yes, that too: In an almost identical program this works perfectly. I can also write to both IMUs.

I didn't get an issue with the above example - just multiple writes to i2c as expected.
So what changed?
I notice a comment about the RGB LEDs initialisation not working in a macro too - more weirdness...

Hi Martin
My program works again!
I can set the LSM6 with I2C master and I can read LSM6 with I2C master
I had to set all I2C components to ch2!
With almost the same program on I2C ch1 it works fine...
Thank you very much for your support Martin.
for the RGB Led I wrote a new post:
