Description
I am trying to communicate NUCLEO-F756ZG board that contains STM32F756ZG with a 4 inch LCD display with ST7796S driver IC : ( MHS-4.0inch Display-B - LCD wiki ) by using STM32CubeIDE and 1 guide posted on the LVGL website : ( Step-by-step Guide: How to use the LVGL v9 LCD drivers with STM32 devices — LVGL documentation ) and display some words like “Hello world!” but after I added the code written in thee guide to my main.c on the IDE even though the code is running without any error somehow the display isn’t showing anything but the backlight flashing.
What MCU/Processor/Board and compiler are you using?
NUCLEO-F756ZG (STM32F756ZG)
STM32CubeIDE
What do you want to achieve?
Show “Hello World!” on the diplay.
What have you tried so far?
After following the guide I fixed all the errors that appiered so now there aren’t any error.
Exchanging the value written for resolution in horizontal and vertical.
Changing the screen color from white to black and text color from black to white.
