Circuit Function and AdvantagesThe reference design shown in Figure 1 is a high-resolution, wide-bandwidth, high-dynamic-range, IEPE (Integrated Electronics Piezoelectric)-compatible interface data ac...
I just started learning UCOS and don't have time to read books, so I have to ask you here first.During the IRQ interrupt processing of UCOS (ARM9 platform), we can see that the IRQ mode is switched to...
[i=s]This post was last edited by spacexplorer on 2014-7-11 09:48[/i] The free boards of the HELPER2416 student aid program were all sent out yesterday. I believe many people have received the boards....
Can anyone explain this in detail? This is what I personally think: Users use QT or direct C language to call the driver that has been written (of course the driver has been compiled into the kernel) ...
I want to choose a xilinx FPGA model. The specific functions are as follows: Complete the encoder feedback function of ten inputs, which also includes the counting unit and the filtering unit. Can som...
The accuracy requirement is not high, maybe 1%, but it needs to be durable, applicable and low price. Please give me some advice from professionals....
Since AC mains power may experience power outages, voltage sags and surges, continuous undervoltage and overvoltage, and frequency fluctuations during supply, these factors will affect the continuous ...[Details]

The power supply is the core component of a computer. Although it is not of high value, all computer components rely on the switching power adapter to provide energy, so the stability of a power su...[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]
There are many types and styles of digital voltmeters in design and development. Traditional digital voltmeters have their own characteristics. They are suitable for manual measurement on site. Tra...[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]
Fairchild's FAN6208 is a synchronous rectification (SR) controller for isolated LLC or LC resonant converters that can drive two individual SR MOSFETs emulating the behavior of rectifier diodes. FAN62...[Details]
