The PWM output mode of GD32F4xx controls the transformation of the lamp

Introduction to PWM principle PWM basics 1. Introduction to PWM PWM (Pulse Width Modulation) is a very effective technology that uses the digital output of a microprocessor to control an analog circuit. PWM is a method of digitally encoding the level of an analog signal. Through the use of high-resolution counters, the square wave duty […]

Use STM32CubeMX to configure FSMC module to drive LCD screen (based on punctual atomic process)

Foreword In the process of learning STM32, I just learned the LCD screen. I use STM32F103ZET6, and the screen is punctual and atomic. But I encountered a lot of problems when lighting up the LCD screen in my own new project. After solving it, share it here, hoping to help friends who encounter this confusion. […]
