Hello everyone ,
I am Yugenthar .Now working in stm32f746-dosco board LTDC concept Try to display the image throught RGB LTDC Signal
But I cannot able the display the image. but code working no error is comming .
step;
1.i have convert to image to LDC image convertor app (is convert image to c-header file)
then i give my main code Please give the sollution .
#include "main.h"
#include "bird1.h"
