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]
For STM32, there are two ways to reset the software: 1) Use the official software library The system reset function is directly provided in the stm32f10x_nvic.c file of the official software li...[Details]
In the actual project development process, it is common to encounter modifications to the hardware circuit, and then the modified part requires the modification of the driver. Thinking about the comi...[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]
I have been working on this i2c for several days. Many people on the Internet say that this is a problem with the ST package library, and they basically talk about the STM32F1 series of chips, and ev...[Details]
1. Initial understanding of FSMC: FSMC consists of 4 modules: (1) AHB interface (including FSMC configuration register) (2) NOR flash memory and PSRAM controller (when driving LCD, LCD is like a PSRA...[Details]
Recently, the relevant person in charge of the Energy Conservation Division of the Energy Conservation and Technology Equipment Department of the National Energy Administration said on the issue of...[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]
First of all, security practitioners have never felt that AI can be used as deeply as today. Although Antelope Cloud is a platform manufacturer, it has always been interested in AI and AI- specific...[Details]
Different models of PIC series microcontrollers have different watchdog settings. The following takes the PIC16F688 microcontroller as an example. 1. If WDTE=1 in the configuration word, the watchdog...[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]
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]
