I used an active crystal oscillator as input, and programmed a decimal counter inside it. Using an oscilloscope, I found that the output of the first few bits was still a sine wave, but the output of ...
This program uses a 51 single-chip microcomputer to control L298, outputs pwm waves to control a DC motor, and there are no errors in debugging. Keyboard control was added. Then a strange problem occu...
Recently, due to work needs, I have just come into contact with UCOS ii. The original author used the Borland compiler. What I want to ask is, can I use other C language compilers, such as MingW? In a...
The generation of electric current is due to the establishment of field strength pulling electrons to form. The establishment of field strength is very fast and equal to the speed of light, so the cur...
I received Launchpad yesterday afternoon, which was the sixth batch of shipments. It was delivered by SF Express, which was great.For the first time, I saw the true face of a capacitive touch panel. I...
Bluetooth devices operate in the ISM band and use Gaussian frequency shift keying ( GFSK ) digital frequency modulation technology to achieve communication between each other. The devices use time div...
