What is the best way to learn how program Graphics on LCD

danieljackmorle — Tue, 15 Mar 2016 01:58:33 GMT

I am looking for a development Kit to run a small video in an LCD window. I am mostly a hardware engineer and it has been 6 years since I developed code. I am thinking the K70 is where I am starting. The demo online does what I want. I also want a USB peripheral. The question is what is the best way to learn how to do this large task. I am also looking into Easy GUI or embedded wizard.

Hi Daniel Morley ,

We don't have a video player solution for the K70. It is possible with some limitations to play videos. Cortex M4 doesn't have enough performance for running video decoders.

You can check with Motomic. A better solution would be the MCIMX6UL running Linux.

You can also check the LPC based solution:

I decided to ax the video. Sounds too complicated. Do you offer a LCD color display interface solution. Defiantly trying to work with out an operating system.

Hello,

You can use eGUI with MQX or bare metal. Use the latest sources:

Does the MQX require an operating system? I like the prices on this part better.

Hi,

MQX is an operating system. www.nxp.com/mqx

eGUI is the graphic library. www.nxp.com/egui

eGUI doesn't need an Operating system.

Hi Luis

I looked at both K70 and the MX6 and I decided to go with the MCIMX6UL mostly on your recommendation and the fact that the chip cost less than the K70. I want to . use the following kits to get started

LCD8000-43T

i.MX6UltraLite Evaluation Kit (EVK)

What kind of compiler does this require

I would like to follow a path that is well explored. You mentioned an embedded Linux solution. Would that have some sample software that I could use?

My goal is to use the kits to get more familiar with the processes.
