Key points: This paper analyzes the problems existing in the realization of equal-precision frequency measurement, and introduces a frequency measurement technology based on adaptive frequency divisio...
As shown in the figure, the voltage at the source of the diode will be equal to 24V + the voltage generated by the inductor of the solenoid valve when the solenoid valve is reset.
If this voltage can ...
I'm looking for friends who can use VB to develop software. The most basic function of the software is to package the data on the screen into a certain format and send it out through the network card ...
1. After testing the onboard Bluetooth, I didn't have time to develop a driver. In fact, this is a full-featured Bluetooth module of TI 2640, which supports Bluetooth 4.1 and audio. So the driver is a...
Freescale is doing a lottery training for microcontrollers. I went to listen for a while. It's not bad. There are not many manufacturers that can provide free online training now. RS08 core and RS08KA...
SensorTile.box does not have an onboard emulator. The emulation interface is a 1.27mm pin header. If you want to download the program without an emulator, you can use the USB DFU function
The method i...

In the actual project development process, hardware circuits often need to be modified, and the modified parts need to modify the driver. Thinking about the coming and going of such requirements is t...[Details]
The program got stuck during LCD initialization. Through hardware debugging, it was found that it was stuck in the Delay_ms() function. Going to the definition, it was found to be a macro definition ...[Details]
In the previous article, I wrote a simple GPIO running light test, which looked a bit monotonous. I was used to serial port debugging. If there was no serial port on the board, I had to find another ...[Details]
introduction STM32 has many registers, which are difficult to remember, so the official packaged two sets of library functions. One is the standard library, but the official has not updated it on F7,...[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]
In 1952, Bell Labs built a 6-foot-tall automatic number recognition machine called "Audrey", which could recognize the pronunciation of the numbers 0 to 9 with an accuracy of more than 90%. And its...[Details]
When designing a product, if the application environment's requirements for power isolation are not considered, the product will be unstable due to improper design, and even high voltage may damage t...[Details]
