I have been studying analog chip design for microelectronics at Fudan University for five years, and I have been working for five years now. During this period, I have listened to the advice of many e...
[size=4]Circuit and working principle: [/size] [size=4]When the positive half cycle of the input voltage passes, the detector tube VU2 is turned on to charge the capacitors C1 and C2 until the peak va...
Recently, there is a small topic: Use CPLD and STM32 microcontroller to design a board with 12 signal input interfaces (each interface is independent and has its own fixed address). When 1 to 4 square...
I made a stopwatch program for students to refer to. We have covered all the knowledge points involved in the program, including timers, digital tubes, interrupts, buttons, and other knowledge points....
[Ask if you don't understand] The principle of an overvoltage and overcurrent protection circuit is explained in the following way in the textbook: As long as there is an overvoltage or overcurrent Uo...
