eLCDIF_t4

This library is experimental, and is dedicated for use with the Dev board v4 found on PJRC forum - https://forum.pjrc.com/index.php?threads/call-to-arms-teensy-sdram-true.73898/#post-334006

The purpose of this library is to display image data on an RGB display using the built in LCD controller of the IMXRT1062 chip by NXP - the eLCDIF controller.

Information about this peripheral can be found in the reference manual, chapter 35.

In order to display data on screens larger than 320*240px @ 16 or 18 bit color depth, external SDRAM is needed (which is only available on the dev board/custom board) and requires the experimental SDRAM_t4 library (https://github.com/mjs513/SDRAM_t4).

Usage:

Include the library using:

#include "eLCDIF_t4.h"

Create an lcd object using the eLCDIF_t4 class

eLCDIF_t4 lcd;

Create a config structure using the lcdif_rgb_mode_config struct

eLCDIF_t4_config config;

Call the begin function passing though the following arguments:

• Bus width with the following options: BUS_8BIT, BUS_16BIT, BUS_18BIT, BUS_24BIT
• Word Length (color depth) with the following options: WORD_8BIT, WORD_16BIT, WORD_18BIT, WORD_24BIT
• Config - referance your config contructor into the begin function

begin(BUS_24BIT, WORD_24BIT, config);
