I want to make a USB virtual serial port program in Windows CE. The physical connection is USB, but the actual serial port reads and writes data. It would be best if there is an example code. I would ...
I use the monitor to get the following serial port requests on the serial port. Which two APIs should I call to get the following requests? IOCTL_SERIAL_SET_WAIT_MASK IOCTL_SERIAL_WAIT_ON_MASK PS: For...
1. Minimum flow problem The amplitude of the vortex signal is proportional to the square of the flow velocity and density of the measured medium. That is to say, when the detection sensitivity of the ...
Designers use PSpice primarily to simulate analog circuits. However, it can also be used to simulate digital filters. The main components in a digital filter are delay elements, adders, and multipl...[Details]
Medical and industrial applications often require isolation voltages of 2500Vac or higher for patient and equipment operator safety. The isolation barrier must not only transmit power to the sensin...[Details]
The particularity of portable medical devices determines that they should be user-friendly, must work in a sterile environment, and occupy little space and consume low energy.
At the same time, por...[Details]
TD-SCDMA terminal conformance test includes three types of tests: RF index test (reference standard: 3GPPTS34.122), protocol signaling test (reference standard: 3GPPTS34.123) and other tests (refer...[Details]
Designers of handheld products such as cell phones, digital cameras, MP3 players and personal digital assistants (PDAs) are continually challenged to deliver more functionality in a smaller form...[Details]

A well-designed electronic load is not designed just for use in the lab; it should be carefully designed and built to test actual power systems. This is true for military portable systems, such as ...[Details]
1. Introduction
The UCC28051 reference design is a 100W offline AC/DC voltage converter with power factor correction (PFC). This power module design is intended to illustrate how to proper...[Details]
Overview
In recent years, the vigorous development of integrated circuits has created a huge space for the research and application of digital circuits. FPGA has low power consumption, high re...[Details]
Introduction
The MAX2116 P1db data is measured at specific combinations of RF and baseband gain over the adjustable range of these two gains. These data can be used to select gain control se...[Details]
Power Integrations (PI) has introduced three charger/adapter reference designs using its new LinkSwitch-II series of AC-DC switching power conversion ICs. The new LinkSwitch-II devices use high-pre...[Details]
Combined with Samsung's ARM9 series embedded processor S3C2410, this paper explains how to perform modular programming of LCD driver and how to statically load the driver into the system kernel.
