For v2 firmware I found some C code to read from this sensor, https://github.com/OLIMEX/OLINUXINO/blob/master/SOFTWARE/iMX233/MOD-TC-MK2/main.c
For v3 firmware I am struggling to read from the i2c so I was wondering if there is an updated version of this code for the new firmware?
What I'm finding confusing is that when I try the GET_ID command (send 0x20 over i2c) the data returned is 0xa7 instead of the expected 0x27. ???
