CFAF800480Hx-043Sx

This is Arduino sample code for the CFAF800480Hx-043Sx family of displays. These displays are 4.3" TFTs which use the Sitronix ST7262 LCD controller. This LCD controller supports a 24 bit parallel RGB interface. This demonstration code has been written for usage with the BT817 Embedded Video Engine.

BMP_DEMO - Toggled to 1 will display "splash.a8z" (after it has been written to flash using PROGRAM_FLASH_FROM_USD (1))
BMP_SCROLL - Toggled to 1 will display "clouds.a8z" (after it has been written to flash using PROGRAM_FLASH_FROM_USD (1)) scrolling across the screen
LOGO_DEMO - Toggled to 1 will display the Crystalfontz Logo from "Round_Logos.cpp"
BOUNCE_DEMO - Toggled to 1 will show a ball bouncing around the screen
MARBLE_DEMO - Toggled to 1 will demonstrate the earth rotating and bouncing around on the screen in place of the ball (after bluemarb.a8z has been written to flash using PROGRAM_FLASH_FROM_USD (1)
TOUCH_DEMO - Toggled to 1 will enable the touch screen (only compatible on touch versions of the display)
