Hello, masters. I just learned microcontrollers. I wanted to use a timer to make a running light, but there was no running effect. After the program was burned in, the lights were all on. I don't know...
Regarding the understanding of CASE statement parallelism, I feel that general CASE statements have priority in terms of syntax, and the CASE branch items in front are executed first, but why is the C...
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]
The day before yesterday, I learned about STM's Systick and found it quite useful for precise timing. When I used CVAVR before, I found that the delay.h in it was very useful. So, I used STM32's...[Details]
Friends who work in the photovoltaic industry, do you still remember the hard work on June 30 last year? How many people worked late into the night for months in a row just to connect to the grid a...[Details]
stm32cubeMX graphical configuration content STM32CubeMX is part of the original STMCube initiative from st microelectronics, and STM32Cube includes STM32CubeMX. STM32CubeMX is a graphical software co...[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]
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]
I rewrote the main part of this program. The program uses the watchdog as a normal timer and scans the digital tubes in the watchdog interrupt. In addition, I added a display buffer. If you want to d...[Details]
As a leading company in automotive semiconductors, Freescale and Khronos Group have jointly launched an automotive multimedia embedded microprocessor i.MX35 with an integrated OpenVG hardware acceler...[Details]
STM32 has two watchdogs: independent watchdog and window watchdog. This article mainly introduces the use of independent watchdog. Independent watchdog (IDWG): driven by an independent 40KHZ low-sp...[Details]
The single-chip microcomputer running light program requires all 32 serial ports to be used, and each serial port has eight LEDs. Question supplement: The 8051 single-chip microcomputer is used, an...[Details]
A simple experimental programming question for the microcontroller: write a 3-byte binary addition subroutine. The program entry is: addend 1: 22H, 21H, 20H three bytes, 22H is the highest bit; adden...[Details]
Design a program for the 51 single-chip microcomputer. It is known that the crystal oscillator frequency of the 89C51 single-chip microcomputer is 12MHz, and it is required to use T1 timing to output...[Details]
