You need to define the constants before including the library so
But there might be some issue with the order of defines and the Arduino preprocessor.
In any case that is a horrible way to do whatever you are trying to do (I can't quite figure it out), if you want to transfer text to write out on a display look at https://github.com/HelsinkiHacklab/reactor/blob/master/software/mwdisplay/mwdisplay.ino (it only has a few 7-segment displays but the same idea can be applied to any lenght of string you can fit into RAM).
Thanks Rambo, it works perfect. In fact the sketch only sends the data recibed packet size to the master. I want to control the attiny for different tasks like a mini DAQ system. I will check your example as guideline for my project.

Hi Rambo, congratulation for your job, your library works fine, thanks!
I have a question, the max value for .available() is TWI_RX_BUFFER_SIZE-1, by default this value is 16-1=15. I cannot change the value defining TWI_RX_BUFFER_SIZE with 32,64,etc. into a sketch, always gives me a max value of 15. Why this occurs?
A part of my code(the relevant for this issue)
define TWI_RX_BUFFER_SIZE ( 64 )
define TWI_TX_BUFFER_SIZE ( 64 ) //This do not works
void receiveEvent(byte howMany)
{ tws_delay(40); //waits all data reg=TinyWireS.available(); //this value has a max value of 15 while(TinyWireS.available()) { char c = TinyWireS.receive(); //Flush buffer } i2c_regs[0]=reg; //prepare "reg" value to send into the next request reg_position = 0; }
