Hi, I'm trying to combine two projects on to the Pro-Trinket 5v; one of the project is a 7-segment LED clock on a backpack and the other is a BMP180 barometer on an RGBLCD display. Are the two libraries (Adafruit_LEDBackpack.h and Adafruit_RGBLCDShield.h) compatible to be used in the same sketch to allow the hardware share the same SDA & SCL, A4/A5 pins, on the ProTrinket?
I am asking because when I do that the clock and the LED runs but the RGBLCD unit displays only all bright blocks & I can't tell if the BMP180 is even working; but each project will run fine independently on their own sketch on the ProTrinket of course.
Just wondering if I need to somehow separate or isolate the SDA/SCL connections by address or something when they are in the same sketch and sharing the same A4/A5 pins. I'm hoping I don't have to but please let me know.
Thank you.

i2c devices need to have unique addresses but, in most cases can share the pins. If you post your code we can have a look and see if there is a way to make it work. Please use the </> button and paste your code between the
