How do transistors drive dot matrix?
Using Protues as shown in the picture, the base can't drive the dot matrix whether there is a level or not. In addition, the transistor can light up the dot matrix without connecting to the power supp
Sine wave oscillator explanation
I am a beginner. I am learning analog electronics. I saw a sine wave oscillator and tried to make one myself. However, the output waveform is as shown in the figure below.I hope the big guys passing b
stm32 stop mode wakeup problem
Help! Now I use stm32 to wake up and use PA8 pin as external interrupt wakeup, but I want to wake up stm32 after the level of PA8 pin is stable. It seems that stm32 does not have such a level-triggere
Phase shift algorithm implemented in DSP
This article is from HELLODSP. I saw a friend asking how to achieve phase shift in DSP. I thought that the software implementation method should be simpler than the hardware implementation, and it can
