I use CH7005 to convert LCD signal to VGA output. It can output in VGA at 640*480 resolution, but it cannot output in 800*600 resolution. [color=#0000FF]The relevant registry configuration for 640*480...
Last time (https://bbs.eeworld.com.cn/thread-440392-1-1.html) we explored a particularly interesting MSP430 property: Although the MSP430 has a wide supply voltage range (1.8 to 3.6V), power consumpti...
I pay close attention to the development of chips in my country. What particularly touched me was our own chip, the Loongson. As for Loongson, I may only know it superficially, not from a technical pe...
[p=28, null, left][color=rgb(51, 51, 51)]In daily programming, the functions that may be implemented are the same, but others want to write faster, better, and the code execution efficiency is also hi...

Microchip's PIC18F46J50 is a low-power, high-performance 8-bit USB microcontroller (MCU) using nanoWatt XLP technology. The current in deep sleep mode can be as low as 13nA, the operating voltage i...[Details]
All electronic design engineers and scientists have performed electrical signal analysis, or signal analysis for short. Through this basic measurement, they can gain insight into signal details and...[Details]
Introduction
Power subsystems are becoming more and more integrated into the overall system. Power systems have moved from being separate "essential dangerous devices" to being monitorable...[Details]
Two simple circuits are implemented to drive two LEDs from a battery powered microprocessor.
This design is based on a circuit that uses three resistors and a microprocessor I/O pin as an input h...[Details]
In the previous series, we have listed some basic knowledge of C language in Tables 1 to 3. We hope that beginners can strengthen their memory of the above tables and gradually learn to use them wh...[Details]
1. Introduction
At present, most lighting equipment still uses traditional energy for lighting. Making full use of solar energy as the energy supply for lighting equipment is of great si...[Details]
1. What is temperature?
Heat is a type of molecular motion. The hotter an object is, the faster its molecules move. Absolute zero is defined as the temperature at which all molecular motion ...[Details]
Microcalorimetry
is used to determine energy relationships. Microcalorimetry techniques are often required when performing calorimetric experiments with small sample sizes or slow heating rat...[Details]
Aromatic gases are widely present in food, medicine, cosmetics and various daily chemical products, such as snacks, liquor, spices, Chinese herbal medicines, plasters, perfumes, soaps, shampoos, et...[Details]
Overview:
This paper introduces a method of connecting a CAN-bus network with Ethernet to form a medium-sized remote monitoring/data transmission network.
CAN (Controller Area Network) is ...[Details]
On the afternoon of July 10, Beijing time, Taiwan's largest chip designer MediaTek expects its smartphone chip shipments to grow by double digits in the third quarter of this year, and the company is ...[Details]
Many battery-powered systems require a visual indicator to show when the battery needs to be replaced. LEDs are commonly used for this purpose, but they consume at least 10mA of current. This con...[Details]
The concept of state machine
State machine is an important concept in software programming. More important than this concept is its flexible application. In a clear and efficient program, ther...[Details]
1. Disadvantages of choosing too high a voltage level
Choosing too high a voltage level will result in too high an investment and a long payback period. As the voltage level increases, the...[Details]
Abstract: Aiming at the needs of coal-rock acoustic emission signal monitoring system, a data acquisition circuit with 24-bit resolution and 16-channel synchronous data acquisition function is desi...[Details]
