The so-called pipeline processing, like the production assembly line, divides the operation execution workload into several time-balanced operation segments, which are continuously input from the star...
I am not clear about the process of soft reset of the system. I don’t know whether the address at which the soft reset starts is the same as that at which the system starts cold start. . . ....
I want to ask, I output a certain frequency pulse (such as 500Hz) from P1.2, why is its output frequency unstable? It keeps decreasing, like 499, 498, and the higher the output frequency, the more uns...
RSEL2~RSEL0: Select a certain internal resistor to determine the nominal frequency (0 is the lowest, 7 is the highest) 1 What is the nominal frequency? 2 What is the lowest? What is the highest? 3 Wha...
I was looking at the msp430g2553 example code on CCS5, and there was a sentence "// Built with CCS Version 4.2.0 and IAR Embedded Workbench Version: 5.10", is it true that in addition to the 430 examp...
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]
1. Principle 1. Infrared emission protocol The infrared transmission protocol has been written in the previous article , so I will not repeat it here. 2. Timer counting and input capture A timer...[Details]
Recently, the " ZTE

service, the outside world was not optimistic about this direction, as it had high investment, low profits and many uncertainties. Let's follo...[Details]
In Windows environment, the source code is encoded in UTF-8. If the source file created by STM32CubeMX contains Chinese comments, then using STM32CubeMX to regenerate the source code will cause the C...[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]
Because the STM32 HAL library only has millisecond-level delay for HAl_Delay(), in order to achieve accurate microsecond-level delay, Systick has to be modified. However, since it is used internally ...[Details]
I used STM32CubeMX V4.22.1 to generate a project including EHT and Lwip. The debugging has been abnormal. After careful inspection, the following problems were found: 1. The hardware uses LAN8720A, b...[Details]
This is my first time writing an STM32 program. I have many questions to ask. I want to convert the data of the SO of MAX6675 into the actual temperature and read it out using the serial port tool. I...[Details]
From last year to now, competition in the photovoltaic inverter industry has become increasingly fierce. In addition to the introduction of new products, various marketing and promotion methods hav...[Details]
Since China began to try to produce panels independently in 1998, in 2018, China's panel industry has gradually upgraded from a marginal industry to the largest production scale. Especially in the ...[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]
The adoption rate of serverless
