//screenDat is of type  uint16_t[128*128]; Holds a copy of the screen's color data 
//readLoc is of type    byte*; Points to start of screenDat, reads it byte by byte (for speed)


//This function outputs screenDat one byte at a time via 8080 parallel
void LCD::tick(){//Updates the screen data. NO MORE OFTEN THAN ONCE EVERY 25 CYCLES(100 ns) - WILL BREAK EVERYTHING

	GPIO.out&=(~0b111111111111);                       //Unset all 8080 pins, CMD mode
	
	__asm__("nop\n\tnop");                             //Delay a little. May be unnecissary
	
	GPIO.out|=  0b011000000000|(*readLoc);             //Enable write and chip, write data, DATA mode
	
	readLoc++;                                         //Increment address, not value!
