Application note
LED dimming implemented on STM32™ microcontroller
1
Introduction
This application note deals with the general principles of LED dimming. This note also
focuses on the use of pulse width modulation (PWM) for digital dimming. Its implementation
on the STM32™ microcontroller in combination with the STP24DP05 LED driver is
described in detail and the most common design approaches are compared.
The conclusion helps developers choose the best approach for their LED dimming
application.
