STM32F429I DISCO LCD Help

[abotha]

Posted on December 17, 2015 at 14:03

Hi Guys.

I recently picked up the above-mentioned evaluation board. I am currently using TrueStudio. I want to display text strings on the on-board LCD. I have been trying to butcher one of the examples to include and use ''stm32f429i_discovery_lcd.h'' library but without any success. I seem to run into all kinds of issues when trying to compile. Does anyone have an example regarding which files should be included and in which sequence do I initialize to display text on the screen? This is what I currently have, but not yet compiling. I will update as soon as I have something that compiles. Help would be greatly appreciated.. Thanks! AJBotha

These are the compile errors that I get. I checked the location of the ili9h and the file is there, don't know why the compiler can't find it?   I think the sdram error is the real issue.    15:34:11 **** Incremental Build of configuration Debug
