Configure the LTDC peripheral<\/b><\/span><\/p>\n

Let’s create a new function called “LTDC_Init” to configure the LTDC peripheral. Our task is to set the background color of the LCD module to red by configuring the LTDC peripheral.<\/span><\/p>\n

Since we have already initialized the LCD module with several commands, it is now ready to receive signals over the RGB interface. Enabling the LTDC peripheral and configuring it to send the red background color should result in the display of the color on the LCD module.<\/span><\/p>\n

To begin initializing the LTDC peripheral, we need to modify various configuration registers. Therefore, we must first enable the peripheral clock for the LTDC. This can be achieved in the APB2ENR of the RCC since the configuration registers of the LTDC fall under the APB2 clock domain.<\/span><\/p>\n

To enable the clock, we can use the following code:<\/span><\/p>\n

REG_SET_BIT(RCC->APB2ENR, RCC_APB2ENR_LTDCEN_Pos);<\/b><\/span><\/p>\n
