LTDC application examples

Due to the R85 pull up resistance, the backlight is at its highest level by default if the

LCD_BL_CTRL (PK3) pin is kept floating so there is no need to configure this pin.

Enabling LTDC interrupts

The FIFO underrun and transfer error interrupts are enabled in the hal_ltdc driver

HAL_LTDC_Init() function. So the user should just enable the LTDC global interrupt on the

NVIC side.

To enable the LTDC global interrupts using STM32CubeMX, select the configuration tab

then click on the LTDC button as shown in Figure 38.

In the LTDC configuration window shown in Figure 42 select the NVIC settings tab, check

the LTDC global interrupts then click on the OK button.

LTDC peripheral configuration

This section demonstrates how to configure LTDC clocks / timings and layer parameters

using the STM32CubeMX tool.
