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]

We have come a long way from the 2G era, and now 5G is about to be commercialized. Suddenly, we realize that time has passed quickly, but technology has never stopped. The activation of 5G heralds ...[Details]

Recently, there was news that the US government asked Google to shut down the Android operating system for ZTE phones. After that, some people even imagined what the consequences would be if Intern...[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]

LAN8720 configuration:  IP: 192.168.192.30  Gateway: 192.168.192.1 A high frequency of ARP packets is detected The content of the packet asks for the mac address of 192.168.192.1, and asks the resp...[Details]

Superconductors have physical properties such as zero resistance effect, Meissner effect and Josephson effect, which make them have broad application prospects and unparalleled advantages in many b...[Details]

Analysts have sorted out some interesting phenomena. Let's follow the embedded editor to learn about the relevant content. Huawei emerged as a star in the all- flash array sales ra...[Details]

This routine is also a classic routine on the development board. I modified the framework of the program to make it more suitable for future calls. The specific 4*4 keyboard scanning principle is rel...[Details]

    This paper combines embedded control technology with network control technology to realize the design of temperature control system based on single chip microcomputer through Internet control. Th...[Details]

In recent years, the application of high-brightness LED has developed rapidly, especially in signboards and traffic lights. For automotive applications, LED is also very attractive. Long life, shock ...[Details]

STM32 Watchdog Summary I have been adjusting the development board of Atom Brother for more than a year, and it is basically usable, but I still don't understand the working mechanism of some basi...[Details]

The independent watchdog of STM32 is driven by a dedicated internal 40Khz low-speed clock, that is, it is still effective even if the main clock fails. Here we need to note that the clock of the inde...[Details]

The pins of stm32 have two uses: GPIO (general purpose io) and AFIO (alternate function io) For some pins (depending on the chip), neither of these two uses exists. For example, in 64-pin products, O...[Details]

The clock system of STM32 can be directly summarized in a diagram (from the STM32F10X reference manual).  The following is an analysis of this diagram 1. STM32 input clock source 1.1 Function of cl...[Details]

I have encountered many problems when tinkering with LD driver recently. I will record them one by one below. Otherwise, who will remember who in five hundred years? 1. Configuration issues of multi-...[Details]
