Text LCD - printf

Hi mbed community,

I´ve been reading this library, and I have two questions to ask you.

1) Where is located the implementation of the printf routine? I can´t find it in file: textLCD.cpp

2) In the constructor of this class, three "Display settings are sent". That´s ok, but why they are sent like:

writeByte(0x3); instead of: writeByte(0x30);

Thanks and best regards,

Emanuel
