And I believe I have my ADS1115 working with my Pi.
Hope this helps someone and I welcome feedback.

Thanks Mike. I am pretty new at this, I downloaded the tarball, ran make, ran main, and this is what I got.

Code: Select all

$ sudo ./main
Failed to write device(-1): Input/output error
Failed to write reg: Input/output error
Difference 0 and 1 = -29555
Failed to write device(-1): Input/output error
Failed to write reg: Input/output error
Difference 2 and 3 = -29300
Failed to write device(-1): Input/output error
Failed to write device(-1): Input/output error
Failed to write reg: Input/output error
Camparator = 0

My addr is ground + addr (x48). Any tips?

Thank you.

here is a good place to start

Just ran into the same thing. For a rev 2 (new/latest) Pi, you need to use /dev/i2c-1 instead of /dev/i2c-0
Just edit the two "open" calls in I2C_RW.cpp

Good catch Don, Thanks.
I missed it. I should have read more, in stead of looking at the pictures.
