Currently I have some difficulties on the Discovery Board STM32F429I to control the on-board LEDs via PWM. According to the data sheet of the Discovery Board the LEDs are located on pin 13 and pin 14 (PG13 & PG14).
According to my research, it is possible to solve the PWM control with the on-board Timer to dim the LEDs. In the data sheet of the MCU, I don't see any timer assignments as an alternative function to generate the PWM signal at the LED. Enclosed is the mapping table from the data sheet of the MCU:
Is there no "elegant" possibility to control the on-board LED via PWM?
Which alternative ways exist to control the brightness via PWM of the on-board LED?
Thank you very much.
