I am using the Romeo V2 controller from DFrobot:
http://www.dfrobot.com/wiki/index.php/R … U:DFR0225)
and the ADJDS311 color sensor which is a I2C device, I followed the tutorial on bildr:
http://bildr.org/2012/01/adjd-s311_arduino/
as the controller used in the tutorial is Uno, the connection of I2C device is different from Romeo V2.
I connected the sensor both to pin A4 and A5 in this picture:

and to SDA and SCL pins in this picture
http://www.dfrobot.com/wiki/images/f/fc/RomeoV2R3.png
But none of the two connections worked, when I uploaded the code from
http://bildr.org/2012/01/adjd-s311_arduino/
and
https://www.sparkfun.com/datasheets/Sen … xample.pde
the sensor did not calibrate as it is supposed to be.
in the code, there was
int sdaPin = A4;
int sclPin = A5;
but if I connect the SDA and SCL to pins on Romeo two, shall I repalce the codes with another? then what shall I int?
I guess the problem may also be the connection, but I just can’t figure it out.
can someone help me with the problem?
