uClinux system transplantation based on FPGA and implementation of web-server[1] I have been working on the operating system on niosII recently, and finally implemented a web-server. I would like to s...
Measure six-phase voltages, set the timer2 to 10ms as the reference for the delay. In addition, the output comparison is 500us. In the output comparison interrupt, the software triggers the ADC to sca...
I read a foreign paper about active filters. What does 3-dB frequency at 1 Hz mean? Here is a whole paragraph: All the analogue signal conditioning paths concluded with a corresponding unity gain four...
Does anyone know what the setting up time and sample/update rate MSPS often mentioned in DA chip datasheets mean? Also, what is the fclk (which seems to be the parameter given by Maxim)? Do Maxim's fc...
This chip. Is it a fixed sampling frequency of 1MHz, and the SPI transmission speed can reach up to 20MHz? Is this the correct understanding? eeworldpostqq...
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]
Since the No. 4 blast furnace of Handan Iron and Steel was put into operation in 1993, its external equipment has been seriously aged, and the original PLC control system TDC3000 of the hot blast furn...[Details]
System Overview
The system consists of a signal preprocessing circuit, a single-chip computer AT89C2051, a systematic LED display module, a serial port data storage circuit and system software...[Details]

One in five car failures are caused by batteries, a problem that will become more serious in the coming years as electric-by-wire, start/stop engine management and hybrid (electric/gas) vehicles be...[Details]
DCDC means DC to DC (conversion of different DC power values). Anything that meets this definition can be called a DCDC converter. Specifically, it means converting the input DC into AC through a s...[Details]
This paper describes the design method of electronic multifunctional watt-hour meter, the key technology of hardware design and the software design process. Taking NEC's μPD78F0338 microcontroller ...[Details]
Preface
DS18B2 is generally used in conjunction with a single-chip microcomputer, and there are few reports on
the interface between

Belt drive is a common transmission device used in industrial production. Its commonly used speed detection device is a photoelectric encoder installed at the rotating end of th...[Details]
The embedded network module series products of Yingchuang Company all have a streamlined ISA expansion bus, which usually includes several address buses, 8-bit data buses, read and write control li...[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]
Designing with FPGA, DSP or microprocessor is a critical part of the design and also takes the most time. System-level designers can benefit greatly by focusing their main efforts on system desig...[Details]
UPS is an uninterruptible power supply (UPS). This device can ensure that after a power outage in the computer system, users can continue to work for a period of time and save files urgently, witho...[Details]
Because we often design RF or low-frequency analog circuits, switching power supplies are rarely used in designs. However, in several cases, switching power supplies must be used to meet the perfor...[Details]
