And I am going to connect 2 BMP180 that are already mountes on the break out board. So I do not need to add 2 Pull Up resistors again. Right?
once more I repeat what I want to do. I am going to connect 2 BMP180 presure sensors, mounted on the breadout boards. they both have the same predefined address. because I need to read the data from them with the low frequenca (once per second) I have tp define new I2C pins, to connect them together to Arduino.
thus, I need to copy I2C library in the main library. -I found at lease 4 different types of libraries. one has just header file, one .cpp format,.... I do not even know which one is good to use-
By the way, I tried all, with and without pull up resistors. no one worked. :~
any Idea!!??
