Is it possible to control the 7 segments separately on a 7 segment display with I2C backpack # 1002 from Adafruit. Have tried this with a test file that works on a regular 7 segments CA, but no luck to control each segment with a back pack.
Here is an example were I still work on. This is build up from 4x4 7 segments in red, white and blue. when finished it should have the date, time and year, Also the barometric pressure, relative humidity and temperature. http://www.cjansen.net/images/Arduino/12segments1.JPG
