// SSD2828 MIPI Bridge - Initialization
//
// 2020-07-26 : Adapted for use with RA8876_t3 library by Dean Blackketter
// 2020-04-14 : Ported to Arduino by Craig Iannello
//              Original by Javen Liu
//
// Hard-coded to work with this particular LCD panel:
//
// Brand: EASTRISING
// Model: ER-TFTM0784-1
//        ( 400 x 1280 dots 7.84" color IPS tft lcd )
//
// This code was only slightly modified from the 8051 example code
// written by JAVEN LIU. In his example, he bit-bangs the SPI to the
// SSD2828, and since this only needs to be done on powerup and doesnt
// need to be performant,  I decided to keep it that way to save resources.
//
// I did change the GPIO stuff to be Arduino-oriented rather than Keil 8051.
