Serial port data must be sent according to standard USB keyboard data packets.
For example, to simulate "A" being pressed, the data packets sent by the serial port are: 0x00, 0x00, 0x04, 0x00, 0x00, 0...

Since I changed my profession and no longer engaged in WinCE development, these books are not very useful to me. I also plan to move recently, and it is inconvenient to carry books. I decided to trans...
Yesterday I received my salary. The pre-tax salary on the pay slip increased, but my actual income was less. Damn, when I asked the HR, they said that the company had evaded taxes before, but now that...
[align=left] It is difficult to get useful replies in such an atmosphere of mutual attack. I hope to get valuable opinions like "One Arrow, Multiple Stars". [/align][align=left] [/align][align=left] [...
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]
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]
Abstract: In order to generate a stable excitation signal, the design of a digital frequency synthesizer is implemented on FPGA using Verilog hardware language. The design includes accumulator, wav...[Details]
introduction
For the voltage regulator modules (VRMs) that power the latest computer central processing units (CPUs), power supply designers have historically used multiphase interleaved b...[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. Background:
The instrument system parameter detection and control of the chemical production workshop of Tangshan Coal Gas Coking Plant are all analog instruments, some of which are eve...[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]
This controller uses PIC16C54 single-chip microcomputer as the controller, and it is very easy to use: just connect a telephone line to the loudspeaker through the controller, and you can rem...[Details]
The emergence and development of street lamps are inseparable from the prosperity and progress of cities, which makes street lamps useful. Conversely, street lamps also make the night of the city n...[Details]
The power consumption of a switching power supply includes fixed losses caused by parasitic resistances such as semiconductor switches, magnetic components, and wiring, as well as switching losses ...[Details]
Multimedia processors are often the most power-hungry devices in portable electronic devices. Common ways to reduce CPU power requirements are to reduce clock frequency or operating voltage, but th...[Details]
Dual Tone MultiFrequency (DTMF) signaling is gradually being used in push-button telephones around the world. It quickly replaced the dial pulse signaling used in traditional rotary phones because ...[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]
