We bid farewell to the charming spring and usher in the passionate summer! The summer sun is hot, like a passionate girl, opening its arms to people. The charming sun shines on the earth like fire. Ho...
[i=s] This post was last edited by paulhyde on 2014-9-15 03:59 [/i] Regarding the attenuator: You must use a resistor network, either π or T type, but 40DB+-2DB is hard to achieve with just resistors,...
Someone used the STM32F303 chip to develop a product, using the SPI1 peripheral. The SPI worked in master mode and read the data of the external ADC chip through the SPI interface from time to time. H...
The operating system is wince5.0, and the hardware platform is S3C2440. Question 1: When I use ActiveSync4 to synchronize with the PC, it can connect normally, from PC to board, or from board to PC, c...

With the development of information technology, intelligence, informatization and networking have become the development trend of modern industrial control. Since the 1980s, the rapid development...[Details]
In 1949, after three years of civil war, the Nationalist government was defeated and retreated to Taiwan. The political and academic circles launched a large-scale reflection on why they failed in ...[Details]
The analog watchdog of the ADC is used to check if the voltage is out of bounds. It has two upper and lower bounds, which can be set in the registers ADC_HTR and ADC_LTR respectively. The library fun...[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]
Today I am using the AD function of the stm8s microcontroller. There are ten channels from AN0 to AN9 on the microcontroller. I want to use only three of them, AN5 to AN7. //ADC initialization void A...[Details]
The code for using timer 0 to implement a running light in a 51 MCU is as follows. The LED light is connected to port P1. The code is annotated below, so I won't explain it in detail. My English is n...[Details]
This program sets the LED running light and the 0-16 numbers of the 0th position of the digital tube to light up in a cycle. The digital tube program cannot be put into the main function, because the...[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]
Manually assemble the following program machine code and analyze the execution function of the program segment. CLR A MOV R2, A MOV R7, #4 LOOP: CLR C MOV A, R0 RLC...[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]
