Abstract :
A LED wireless dimming system based on the STM32 is designed in this paper. In the drive power, the single-ended flyback switching power supply topology and Boost is adopted as an LED constant current drive. A STM32 is used as the center controller. The exact timing of the timer is generated by using an adjustable PWM duty cycle which can control the intensity of the LED lights. Infrared remote control is used as wireless control module with the advantages of small size, low power consumption and etc.
