As we all know, chips play a vital role in every smart device, whether it is a PC, a smartphone or a smart wearable device, CPU as a core component is indispensable. However, China is currently unable...
[i=s]This post was last edited by QWE4562009 on 2021-8-20 14:13[/i]What are the advantages of using transistor + MOS over using MOS alone? After all, the battery is a single cell, and it is fully char...
Recently, my leader assigned me to find a program for replacing SIM card of MCU under MTK platform. I only found a program for replacing SIM card of AVR MCU. My leader said it was not good enough. Has...
I just started learning DSP. I recently used 2812 to develop a project. After writing the program into the on-chip flash, a strange problem occurred.After the board was reset, all functions except SCI...
I developed a system using SIM300 and a microcontroller. I use SMS to control the device. The administrator number is stored in the device. Now there is a problem. When I receive a spam SMS from a mob...
This program is written to simulate the serial port hardware mechanism. When used, a timed interrupt can be set with a time interval of 1/4 baud rate. The receiving function is called once for ea...[Details]

1 The significance of using RTOS on MSP430
It is understandable that it is meaningless to use RTOS on MSP430. Because the hardware resources of MSP430 are limited (for exampl...[Details]
With the rapid development of science and technology, especially the widespread application of digital technology and various ultra-large-scale integrated circuits, electronic equipment, especially...[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]
As LEDs continue to improve in almost every aspect of performance and cost, LED lighting is being used in an increasingly wide range of applications, among which LED street lights are a focus of in...[Details]
DSP (digital signal processor) is used more and more frequently in today's engineering applications. There are three main reasons for this: first, it has powerful computing power and is capable of ...[Details]
1. Principle of displacement angle sensor
The angle sensor is used to detect angles. It has a hole in its body that fits the LEGO axle. When connected to the RCX, the angle sensor counts once ...[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]
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]
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]
As a simple and practical input device, buttons have been used in various microcontroller application systems and are ubiquitous. However, the buttons used in different practical occasions are also...[Details]
Among the many members of the single-chip microcomputer family, the MCS-51 series of single-chip microcomputers has occupied the main market of industrial measurement and control and automation eng...[Details]
From the previous section, we have learned that the timer/counter in the microcontroller can have multiple uses, so how can I make them work for the purpose I need? This requires setting the timer/...[Details]
introduction
MAX6636 is a multi-channel precision temperature monitor that can not only monitor local temperature, but also connect up to 6 diodes externally. Each channel has a programmable...[Details]
Capacitance Measurement
Used to verify that capacitors meet the manufacturer's specifications. For quality control, a group of capacitors may be placed in an environmental chamber and the cap...[Details]
