I2C_MASTER and multiple other objects not declared in this scope. Am i missing a header file ?

I have no idea what you are doing.

I2C_Master is not declared when you comment the teensie lib and try to use Wire.h

Most of "error" lines add a commented version, so I have reverted them and it seems to work.

Original code : // Wire.begin(); // TWBR = 12; // 400 kbit/sec I2C speed for Pro Mini // Setup for Master mode, pins 16/17, external pullups, 400kHz for Teensy 3.1 Wire.begin(I2C_MASTER, 0x00, I2C_PINS_16_17, I2C_PULLUP_EXT, I2C_RATE_400);

Code for Wire.h Wire.begin(); // <= UNCOMMENTED // TWBR = 12; // 400 kbit/sec I2C speed for Pro Mini // Setup for Master mode, pins 16/17, external pullups, 400kHz for Teensy 3.1 // Wire.begin(I2C_MASTER, 0x00, I2C_PINS_16_17, I2C_PULLUP_EXT, I2C_RATE_400); // <= COMMENTED

etc.

The question is a bit old, but I thought it might help someone in the future.

Still I'm a bit sorry because you use 2482 bytes of memory and Arduino Uno has only 2048 byte available :p I will try to see if I can get rid of some intermediary variable... :(

Thanks nonetheless for the great code and explanation associated !
