In the RFID system, the working distance between the reader and the electronic tag is an important indicator of RFID application.
This distance is closely related to the cooperation between the RFID t...
I have a design plan: Regarding cutting off the standby power, the US Energy Star is 3 watts, and Europe’s current standby is 1 watt.
My technology is to completely cut off the power supply, and "cut ...
Modern life is changing with each passing day, and people cannot live without electricity. In the process of using electricity, there are problems with electricity safety. In electrical equipment, suc...
Using the serial port debugging tool, the PC communicates with the 430 serial port. The serial port debugging tool can receive the data sent by the microcontroller, but the microcontroller cannot rece...
I plan to use jrtplib3.7 on ARM9 and Linux2.4 as an embedded video service. I can use arm-linux-cross-compile jrtplib without any problems. I wrote the programs for the receiver and the transmitter, c...
[color=#000][backcolor=rgb(232, 232, 232)][size=15px] The problem is this, taking channel 1 of timer 1 as an example, first consider complementary PWM without dead zone, assuming that PWM mode 1 is us...
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]
Today, with the increasing integration of functions, mobile phones can also be used as portable media players (PMP), digital cameras, handheld computers (PDAs), and even global positioning systems ...[Details]
introduction
Throughout the history of automotive lighting, power has always played an important role. Initially, cars only needed headlights to see the road in the dark. Later, other light so...[Details]
