Figure 38. STM32CubeMX: LTDC configuration

In the LTDC configuration window described in Figure 39, select all the LTDC pins then set

the maximum output speed to very high.

Specific pins configuration of the display module

Once that all the LTDC interface pins are correctly configured respecting the LCD-TFT panel

connection, the user should configure the other specific pins connected to the display

(LCD_DISP, INT pin and I2C interface)

The LCD_DISP pin (PI12 pin) has to be configured as an output push pull with high level in

order to enable the display, otherwise the display stays in standby mode.
