For 80,000 ZTE (000063.SZ) employees and more Chinese ICT (information and communication technology) industry practitioners, the news from across the ocean on the evening of April 16 kept t...[Details]

In the actual project development process, we often need to get the running time of a section of code. The usual method is to use an oscilloscope to measure it. This blog post will use SysTick to acc...[Details]

Timing and protocol are two key points in digital system debugging, and they are also where logic analyzers can play their most valuable role. How can we use a logic analyzer to quickly complete wiri...[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]

1) ADC multi-channel acquisition: (Multi-channel acquisition must use scanning mode. In scanning mode, the channels of the rule group share a register, so DMA transmission must be used; to prevent da...[Details]

1. What is PWM      What is PWM? Professionally speaking, it is pulse width modulation. In layman's terms, it is the continuous output of high and low levels. For example, the microcontroller outputs...[Details]

As shown in the figure, the circuit is required to count and display the number of times the button is pressed. When the button is pressed once, the count value increases by 1 (it is required to accu...[Details]

Take serial port interrupt as an example: like: void serial() interrupt 4 { } and void serial_uart() interrupt 4 { } The functions of both functions are to define the serial port interrupt function. ...[Details]

    Each I/O port of the AVR microcontroller corresponds to three registers: DDRx, PORTx and PINx, where DDRx is the data direction, i.e. input or output; PORTx is the state of the internal pull-up r...[Details]

Semiconductor giant Intel has launched the desktop version of the 8th generation Coffee Lake architecture Core processor more than a month ago, and its performance is said to be 30% to 40% ...[Details]

In the first quarter of 2014, Inspur's server shipment market share reached 19%, ranking first in China and fifth in the global market. This is the first time a Chinese manufacturer has ach...[Details]
