I connected the IO port of msp430 to the b pole of PNP, and found that the PNP is turned on when the output is low. I don't understand why the IO should be set as output. When the PNP is turned on, th...
After a long evolution, humans evolved from crawling on all fours to walking upright today, which also includes the evolutionary direction of more sensitive and faster response of human sensor systems...
My experiment is based on an example in Zhou Ligong's "arm&wince experiment and practice". The main purpose is to write a driver and then add it to the operating system to realize automatic loading of...
I want to make three square wave signal sources, and require the input phases of these three signal sources to be 120° apart. How can I do this? I see a clock signal in the signal source, but I don't ...
I have been doing an experiment recently to use PWM to drive an LED on and off. However, the output PWM waveform is as follows.Of course, this amplitude value cannot drive the LED. What do you think i...
