[size=3][font=宋体]Every week I get a lot of emails from people who want to make a robot. Usually they want to make it with simple components, either from home or from hardware stores. As a robot maker ...
Today the outside is yellow, or rather orange, and there was such a thick fog when I woke up in the morning. I don't think I've ever seen such weather. Did 2012 come early? Or was it a sandstorm? Take...
The emulator on the development board accidentally cleared the flash, and now it can only recognize two serial ports. Please help, it doesn't work. Thank you very much!...
LoadDriver and LoadLibrary both load DLLs. The PB help says that LoadDriver can also prevent code and data from being "paged out". What does "paged out" mean here? Under what circumstances will the so...
I originally chose NXP's PCF50633, which has powerful functions, but I don't know how to use it - I can't find any information about the power-on reset value of the register. I have found an agent, se...
There are two small problems in using i2c of DSP. (1) bytein(0xA0 + ((addr & 0x0300) >> 7)); //Write the control word 0xA0 Why not write 0xA0 directly? (2) Also, GPIO uses pull-up mode, SCL_1 ((addr &...
Analog engineers have traditionally struggled with complexity when designing power supplies that required multiple outputs, dynamic load sharing, hot-swap, or extensive fault-handling capabilities....[Details]
The reason for the light decay of white LEDs: the decline of phosphor performance
So far, the rapid decline of the luminous performance of white light LEDs, especially low-power white light LE...[Details]
0 Introduction
High-precision current source can provide high-precision current supply for precision instruments, and is suitable for automatic measurement tasks of various resistors in semico...[Details]
Direct digital frequency synthesis (DDS) has fast frequency switching and modulation capabilities and is widely used. However, when low power consumption and low cost are the main considerations, D...[Details]
The principles to be followed are as follows:
(1) In terms of component layout, related components should be placed as close as possible. For example, clock generators, crystal oscillat...[Details]
Abstract: Based on the analysis of the characteristics of the IRIG-B (DC) code type, a design method for IRIG-B (DC) time code decoding is proposed. This method consists of a small number of periph...[Details]
Traditional synthesis techniques are increasingly unable to meet the needs of today's very large and complex FPGA designs implemented in 90nm and below process nodes. The problem is that traditio...[Details]
Some people think: as long as the program runs well, it doesn't matter how the original program is written. But this is absolutely not the case. Software is not completed in one go, and it is neces...[Details]
Stepper motors, also called steppers, use the principles of electromagnetism to convert electrical energy into mechanical energy and have been used since the 1920s. With the increasing popularity o...[Details]
1 Causes of problems with electric vehicle batteries
1.1 Caused by the battery itself
Why do we say that? In the previous issue, we learned about the working princi...[Details]
Lithium iron phosphate batteries are used as lithium-ion secondary batteries. Their main application is now in power batteries, which have great advantages over NI-H and Ni-Cd batteries.
Lithi...[Details]
With the continuous development of integrated circuit technology, integrated circuits have developed from thousands of gates to the current level of millions and tens of millions of gates. The applica...[Details]
SL11R is a 16-bit RISC microcontroller with a USB interface produced by Scanlogic. Its core processing speed reaches 48MIPS. It has rich hardware resources and 32-bit programmable I/O ports, and ca...[Details]
Abstract: Based on FPGA hardware, the image scaling with fixed magnification is realized. The 2D convolution operation is decomposed into 2 1D convolution operations. The input original image pixel...[Details]
The Challenge:
Protect historical relics by monitoring environmental factors without affecting their original appearance.
The Solution:
Developed a monitoring system for the...[Details]
