Reasons for the failure of stm32 virtual serial port installation-EEWORLD

Collect

I have also seen a lot of people saying on the Internet that the problem can be solved by following the steps below, but unfortunately my pirated system does not work:

Copy mdmcpq.inf to c:\windows\inf

Copy usbser.sys to c:\windows\system32\drivers

However, I still used this idea to look for some reasons and finally discovered that in the c:\windows\inf folder, there is a file named mdmcpq2.inf. On a whim, I wanted to remove the 2 and see if it works. Later, I tried it and it worked. It was successfully installed!

Errors in stm32 and how to solve them

1. error: #256: invalid redeclaration of type name "s32" (declared at line 470 of "C:\Keil_STM32\ARM\INC\ST\STM32F10x\stm32f10x.h") Solution: Open the stm32f10x_conf.h file, comment out "#include "stm32f10x_type.h"" on line 21, save the stm32f10x_conf.h file, and recompile. 2. warning: #47-D: incompatible redefini

How to disable STM32 TIM channels individually

A recent project involves the generation of six-channel PWM. I won't talk about this here. If you don't know, you can refer to my other blog. Here I will talk about how to turn off and on one channel of the timer separately. I refer to the experience of many netizens. I quote their examples here. The purpose is to hel

STM32 controls the output count of 4-bit common anode digital tube

A total of 12 pins of GPIO port PA0~PA11 are used First, the schematic diagram Because it is a common anode, 12, 9, 8, and 6 are power inputs, and the other pins are grounded. So for the chip, 12, 9, 8, and 6 are high outputs, and the others can be set to low. //Set the GPIO port void GPIO_Num_Init(void) {

STM32 GPIO related registers (Part 2)

STM32 microcontrollers can only communicate with the outside world if they have ports. Only by learning how to control ports can we make better use of peripherals, establish connections with the outside world, and give full play to our own advantages. First, let's introduce the basic GPIO related registers:

stm32-GPIO operation (library function)

It's rare to have time, so I want to write about the basics of stm32 recently. 8 ways of GPIO 1. Floating input GPIO_IN_FLOATING ——Floating input, can be used for KEY recognition, RX1 2. GPIO_IPU with pull-up input——IO internal pull-up resistor input 3. GPIO_IPD with pull-down input——IO internal pul

Overview of STM32 clock system

The STM32 clock block diagram is as follows: Important clocks: 1. HSI: High-speed internal clock signal The clock inside the STM32 microcontroller (8M frequency) has poor accuracy 2. HSE: High-speed external clock signal High-precision source (1) HSE external crystal/ceramic resonator (crystal oscillator

Cannot run when using keil to debug stm32

When using Keil, the number of breakpoints cannot exceed 5. If there are more than 5 breakpoints, you will not be able to enter the debugging interface. If more than 5 breakpoints are hit during debugging, an alarm message or error prompt will appear Fixes: Previously, based on experience, the number of breakpoi
