Author: Howard ZouAn operational amplifier is a type of amplifier that can perform different arithmetic operations by changing peripheral devices. Any operational amplifier integrates a lot of transis...
I went to buy a development board today. I originally wanted to buy the 2440 development board from Youshanzhibi, but I heard that there was no BSP6.0 development package, so I decided to buy the 2440...
It was working fine just now, but suddenly it couldn't run after debugging was completed. The run buttons were all gray. I clicked debug, and after it was completed, I couldn't do anything....
ATMEL announces that the AT86RF233 2.4GHz IEEE 802.15.4 radio transceiver supports distance measurement, or ranging, between two radio devices. This innovative technology uses the phase difference bet...
In the development of servo drive, ADC acquisition is the key point. The analog quantities in this development board are: three-phase current, 1 bus voltage, and 1 temperature (onboard sensor). After ...
For STM32, there are two ways to reset the software: 1) Use the official software library The system reset function is directly provided in the stm32f10x_nvic.c file of the official software li...[Details]
When Amazon launched its first
cloud computing
service, the outside world was not optimistic about this direction, as it had high investment, low profits and many uncertainties. Let's follo...[Details]
The last two blogs talked about a version problem of STM32CubeMX and the problem of hardware reset. When you solve these two problems, you will find that after the program is burned into the board, t...[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]
I have been working on this i2c for several days. Many people on the Internet say that this is a problem with the ST package library, and they basically talk about the STM32F1 series of chips, and ev...[Details]
Serial Port: 一. USART_ITConfig(USART1, USART_IT_TXE, ENABLE): As long as the transmit register is empty, there will always be an interrupt. Therefore, if you are not sending data, turn off the tran...[Details]
Automotive LCD Instrument Clock EMI Solution As early as 2014, the market size of China's automotive full LCD instrument has reached 3.506 billion yuan, and it is expected that by 2020, this s...[Details]
Recently, the relevant person in charge of the Energy Conservation Division of the Energy Conservation and Technology Equipment Department of the National Energy Administration said on the issue of...[Details]
First of all, security practitioners have never felt that AI can be used as deeply as today. Although Antelope Cloud is a platform manufacturer, it has always been interested in AI and AI- specific...[Details]
Different models of PIC series microcontrollers have different watchdog settings. The following takes the PIC16F688 microcontroller as an example. 1. If WDTE=1 in the configuration word, the watchdog...[Details]
1) Independent watchdog has no interrupt, window watchdog has interrupt 2) Independent watchdogs can be divided into hardware and software, while window watchdogs can only be controlled by software...[Details]
Use the STM32 timer input capture module to control 3-way ultrasonic sensors. The ultrasonic sensor used this time is the common HC-SR04, which is often used in the obstacle avoidance system of smal...[Details]
The clock system of STM32 can be directly summarized in a diagram (from the STM32F10X reference manual). The following is an analysis of this diagram 1. STM32 input clock source 1.1 Function of cl...[Details]
How to convert the pin voltage value into V using the built-in ADC of STM32? V(ADC) = Value(ADC) * V(ref)/4096 (The ADC of STM32 is 12 bits, so the maximum value of the AD word is 4096)
Where V(ADC...[Details]
