Environmental monitoring terminalAuthor: JohnBrief introduction of the work (100-200 words)
(Design name, work photo, function introduction, etc.)This project is an environmental monitoring terminal t...
I used stm32 to drive the MAX7219 module. I found that the module had different power-on behaviors at different times, and the behaviors were different when the emulator was plugged in or not. I had p...
I want to use a microcontroller to control GPRS through a serial port. The baud rate of the microcontroller is 9600 and the baud rate of gprs is 115200. How can I set the baud rate when gprs and the m...
I connected a pressure sensor, which outputs more than 10mV, directly connected it to the AD channel, turned on the internal buffer, the internal amplification factor is the maximum, the internal refe...
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]
In the actual project development process, hardware circuits often need to be modified, and the modified parts need to modify the driver. Thinking about the coming and going of such requirements is t...[Details]
CMSIS Driver has similar API functions and similar calling methods. It is a further encapsulation based on the ST HAL library. It is much more convenient and simpler to use and configure than the ST ...[Details]
The program got stuck during LCD initialization. Through hardware debugging, it was found that it was stuck in the Delay_ms() function. Going to the definition, it was found to be a macro definition ...[Details]
1. Photovoltaic inverter installation process
1. Preparation before installation
Are the product accessories, installation tools and parts complete? Is the installation environmen...[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]
introduction STM32 has many registers, which are difficult to remember, so the official packaged two sets of library functions. One is the standard library, but the official has not updated it on F7,...[Details]
After studying the F4 FSMC method to drive the touch screen for a few days, I have gained some understanding, which are listed below. The unorganized record is only for my own reference in the future...[Details]
Artificial intelligence
There is no inherent bias in AI. It does not "think" something is true or false for reasons that cannot be explained by logic. Unfortunately, human bias exists in mach...[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]
Different from 51, AVR and other single-chip microcomputers, the clock signal sources of msp430 include LFXT1, XT2 and DCO. 1. LFXT1: It can connect high-speed and low-speed crystal oscillators. In l...[Details]
This paper proposes a design scheme for an embedded CNC system based on ARM and FPGA. The software and hardware design of the ARM system, the implementation method of hardware fine interpolation ...[Details]
Notes on inverter installation and maintenance:
1. Before installation, you should first check whether the inverter is damaged during transportation.
2. When selecting an installa...[Details]
Using the WWDG of STM32F030, it is found that the MCU will not be reset under STOP, just like the sleep mode of STM8S. Paste the watchdog code: /******************************************************...[Details]
