spi_data(0);
spi_data(4);
spi_data(9);
spi_data(15);

2- how he know that 28 is green color:

spi_command(RAMWR); // write some stuff (background)
for (i = 0; i < 18000; i++){
spi_data(28); // 28 is green
}
----------------------------------------------
3-how i can accses certain pixel in lcd and how i can control color of it?
----------------------------------------------
how he use this 2 command :
spi_command(PASET); // page start/end ram
spi_data(2); // for some reason starts at 2
spi_data(131);

spi_command(CASET); // column start/end ram
spi_data(0);
spi_data(131);
value from 2-131what mean and i want more details about ddram how ican work with it? becouse i cant understand how it divided?

in data sheet he put(paset)COMMAND:
for parametre(p1)start page (D0-D7)(P10...P17) WHAT THIS VALUE(P10-P17) AND LIKE THAT IN CASET?
