Help make the library for Arduino Mega R3, this library for peak controller. I'm just a beginner and want to connect a display, but not the library. Or give a advice.

It looks like an I2C device - do you know what the address is?

Commands to display T191 (T190)
Initialization after power:

START 78H 00H 31H 14H 06H 30H 11H 05H 31H 9AH 0CH 30H 0CH 40H 80H STOP

The Contrast: START 78H 00H 31H 9AH STOP,

9AH - contrast. Greater value - more contrast.

Nothing more is known, but to address characters.
How can I start to initialize?
I'm a beginner, Arduino buy yesterday.

It really depends on how confident you are at programming, but if you're learning about C and I2C at the same time, it's going to be tricky.
I'd be inclined to buy an I2C device that is supported and learn from that.

}

display is silent, the light blinks. (
