Hello everyone, I am using the STM32F4 Discovery evaluation pack along with its breakout board and LCD screen. I was trying to write a simple program that adjusts the screen's brightness, however I am out of ideas of where to start. I know that the screen has two inputs to switch on the LEDs which are LED_A and LED_K and it has an output to the microcontroller which is PD13. The question is how can I configure the microcontroller to adjust the brightness? and what shall I change? Any help will be greatly appreciated.
Thanks alot!!
