I hope you’ll have some answers. I have tried to read sensors (
analog, digital, I2C…) on this Cape : grove modules or not. Even the
examples ( fan module, led, 3D accelerator) on the Seeedstudio website
were not working .
Look at the comments there, and the Seeedstudio's team answers :

It seems there is a problem on the TI chip user for the voltage transfer

Faulty chip also on other systems

This Cape (2 ex) was tested with All the « seeed » images downloaded
on the beaglebone site ( 5 at all)
Tested with 2 versions of lib Mraa … 1.0 (from the distribution) and
1.5 (from GitHub).
Python scripts with mraa.Aio(port) end with: ValueError: Invalid AIO
pin specified - do you have an ADC.. on reading any Analog port, and
others non functioning parts can be easily demonstrated.

http://www.exp-tech.de/seeed-studio-grove-base-cape-for-beaglebone?___SID=U) which apparently does not have a populated EEPROM when delivered. According to Seed, this seems deliberate although it would be nice with a default configuration. As an answer to my inquiry regarding this, Seed referred to the EEPROM utiliity created by Josh Datko and hosted on github(
https://github.com/jbdatko/eeprom_tutorial/blob/master/eeprom.md). While I'm prepared to try my luck with this, I'll appreciate if anybody already equipped with this cape would be able to post a suitable image I could burn into my cape.
