When I was referring to the design of an AVR (ATMEGA644PA-AU) chip, I found that the ISP download line uses the SPI port, which is the interface of PIN1, PIN2, and PIN3, while the JTAG interface in th...
The Bluetooth part of KW41Z is finally completed. Actually, it can’t be said to be completed. It is just a transplantation of an existing example. Upload regularly after Bluetooth connection [code]ext...
As the title says, I read the PDF document of C8051F and found that the power supply voltage of C8051F can be 3.3V-5V, but the IO voltage of C8051F is not mentioned in the PDF. So, what is the IO volt...
Measuring AC voltage and frequency1. Measure voltage1. Signal transformation method:
(1) Measure the amplitude point by point and then perform integration operation; this requires a high-speed AD conv...
I encountered a very strange problem. I used SPI to read and store external EERPOM. When the speed was set below 600k, some of the stored data was lost. When it was over 600k, the storage was normal. ...
Hardware designers have begun to adopt FPGA technology in high-performance DSP designs because it can provide 10-100 times faster computing than PC-based or microcontroller-based solutions. Previou...[Details]
A single-chip microcomputer is also called a single-chip microcontroller. It is not a chip that completes a certain logical function, but a computer system integrated into one chip. In general, a c...[Details]
1. Introduction
RFID (radio frequency identification) is a non-contact automatic identification technology that emerged in the 1990s. It uses the characteristics of radio frequency signal prop...[Details]
System design is a complex process. It is not enough to just use ICs. There are many details to consider. This article uses a high-fidelity music playback system as an example to introduce how to s...[Details]
Electronic systems are located at different points on the automotive power bus and therefore often need to operate under very stringent power requirements. These include load dump, cold crank, very lo...[Details]
1. System Structure
This system is a simulation system of indoor air-conditioning temperature/humidity control system. The data acquisition and control center collects temperature/humidity...[Details]
1. Introduction
Testing the temperature of steel billets before rolling is an important measure to ensure the quality of steel. Traditional manual testing is difficult to ensure product qu...[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]
Problems such as the depletion of natural resources, air pollution, traffic congestion, and rising fossil fuel prices have forced societies and individuals to seek alternative means of transportati...[Details]
Motors, especially those with brushes, generate a lot of noise. This noise must be dealt with if the appliance is to meet the requirements of EMC standards. The means to solve EMC are nothing more ...[Details]
The rectified DC voltage is then converted back to AC using power electronics such as insulated gate bipolar transistors.
The output voltage is switched on and off at a high frequency, control...[Details]
In the "digital pressure measurement" experimental device of applied physics, the subject technical knowledge of analog circuits, digital circuits, sensors and single-chip microcomputers is used. In o...[Details]
LED is the abbreviation of the English word. Its main meanings are: LED = Light Emitting Diode, a solid-state semiconductor device that can convert electrical energy into visible light. It can dire...[Details]
Against the backdrop of global warming, energy conservation and emission reduction have become a global hotspot and focus, which has also sounded the clarion call for the take-off of the LED lighti...[Details]
