STM32F469I DISCOVERY LCD
Hi! I'm trying to run TFT LCD at STM32F469I Discovery board, but have som problem. I'm using CubeMX to generate initial code, and SW4STM32 with Eclipse.
I've included LCD necessary .h and .c files from here: https://developer.mbed.org/teams/ST/code/BSP_DISCO_F469NI/
LCD starded, I can change colors but there is problem probably with configuration... There is simple text string "Hello! Hello! Hello!" (yes, 3 times). I'm able also change the text posiotion on the LCD, but still displays only that horizontal flickering lines.... Any suggestion where search problem to start working properly? :)
Thanks and Regards!

Dear Paweł Despite you wrote this post long time ago, and probably you solved it or forget about it I decided to give you the answer, even if you don't need this info already, maybe I will help people which has the same problem :) I had the same problem today and I coudn't find the answer on the internet. In my case the solution was the clock, more precisely too high HCLK value and too high LCD_TFT clocks vaule. For STM32F429I it works well with HCLK = 180MHz and LCD_TFT clocks = 25MHz. Hope it helps :) Kind regards Konrad
