After electronic equipment uses printed circuit boards, due to the consistency of similar printed circuit boards, manual wiring errors are avoided, and electronic components can be automatically inser...
I have always used an external USB keyboard. Today, I accidentally pressed the laptop keyboard and found that numbers popped up after I pressed a few letters. I was so depressed.
For example, when I p...
1. Send a voltage vector to the motor, so that the motor rotates 15 degrees every 0.2s. Is the time interval and the angle of the motor reasonable? In the positioning stage, the voltage applied to the...
Since the German physicist W.K. Reontgen discovered X-rays at the Institute of Physics of the University of Würzburg in 1895, which pioneered the diagnosis of human body effects, modern medical instru...
The chip select of max7221 is valid at low level, and din receives data at the rising edge of clk. But when I simulate, the chip select is always at high level, and there is no pulse on clk, only low ...
TI is a very generous company. For students, the chip performance is very high, enough to cope with various competitions and some daily small projects. First of all, I personally think that there are ...
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]
