At present, the elevator group control system in China has been widely used, but the remote monitoring of group-controlled elevators has yet to be studied and developed. Therefore, the realization of...[Details]

In C51 language, it does not provide input and output statements. Input and output operations are implemented by functions. In the standard function library of C51, a general I/O function library nam...[Details]

The application of PWM can be said to be very wide, controlling motor speed, light brightness, communication modulation and many other fields. My friends have asked me a lot about PWM, and I have bee...[Details]

　　Equipment developed for industrial occasions usually has a 4-20mA output interface. In the past, single-chip systems without DAC modules required an external main chip DAC to realize analog quantit...[Details]

　　In 1976, Intel first produced a microcontroller named MCS-48, an 8-bit microcontroller. Later in 1980, an improved version named MCS-51 (also an 8-bit microcontroller) was released. The 8051 microc...[Details]

Purpose: To test the capacitor and see what it will look like when connected to square waves of different frequencies. Equipment: resistors, breadboard, STM32F103VE experiment board, oscilloscope. ...[Details]

As we all know, the clock system is the pulse of the CPU, just like a person's heartbeat. So the importance of the clock system is self-evident. The clock system of STM32 is relatively complex, unlik...[Details]
