STM32F7 Discovery kit for STM32F746 MCU

Hi,

I started to work with the STM32F7 Discovery kit and according to the instruction I set JP1 to 5V_STLINK and then I connected the USB cable from the kit to the PC to power the board. The outcomes are:

LD7 is red, LD2 is red and the LD4 is green. But the screen brightness is really almost dark! and really difficult to see applications lists.

Please find the attachments.

Kindly help!

Hello @spark​ ,

Configure the LCD back-light control (LCD_BL_CTRL) via PK3 pin. (You can check the STM32F746 schematic). 0693W000005CpP7QAK.jpgEnable the LCD display using the BSP_LCD_DisplayOn() function:

STM32Cube_FW_F7_V1.16.0\Drivers\BSP\STM32746G-Discovery\stm32746g_discovery_lcd.c
