71 / 91 page ![]() DocID029237 Rev 2 71/91 AN4861 LTDC application examples 89 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. Figure 42. STM32CubeMX: enabling LTDC global and error interrupts 6.2.4 LTDC peripheral configuration This section demonstrates how to configure LTDC clocks / timings and layer parameters using the STM32CubeMX tool. |
