1. Principle 1. Infrared emission protocol There are many infrared communication protocols. This experiment uses the NEC protocol. This protocol uses PWM modulation and uses pulse width to represen...[Details]

The update interrupt initialization configuration of the stm32 advanced timer TIM1 is not much different from that of the ordinary timer. What needs to be paid attention to is the configuration of TI...[Details]

Today, under the guidance of a low-level expert, I learned how to configure the PWM module! Woof! First open the file configured last time, as follows:  Then, we need to use TIM1 to set PWM:  Then,...[Details]

The goal of this article is to build a TCP client based on the previous project that can ping the PC, and can actively send data to the PC, and can also send and receive data with the PC, and display...[Details]

Overview Lightning is a strong discharge phenomenon that occurs between thunderstorm clouds and between thunderstorm clouds and the earth due to severe convective weather. Lightning is gen...[Details]
