Detailed description of what a register is and what it can do Through previous learning, we know that the microcontroller has ROM, RAM, and parallel I/O ports. So, in addition to these...[Details]

Specific implementation functions Specific functions: (1) The first line of the LCD displays the actual humidity, and the second line of the LCD displays the current time; (2) Button description:...[Details]

In assembly language, a label represents an address, but in C, to obtain the data at the label, we directly use the label. Shouldn't we perform a value operation on the address (*pointer address)? Act...[Details]

Preface In this section, we begin to learn how to use the 51 single-chip microcomputer to control relays. With relays, we can use the low level output by the single-chip microcomputer to control the ...[Details]

PWM, the full name of Pulse Width Modulation, is translated as pulse width modulation. Function: Change the pulse width to achieve different effects. Digital signals can be used to achieve the effe...[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]

Function Description:      This electronic keyboard is small, pleasant, easy to carry, low cost, beautiful, and can play most music. The 16-key design method used in this work can also be expanded to...[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]

The IO pins of the microcontroller will definitely be used when using it. Take the P1 port of the 51 microcontroller as an example. The internal structure is shown in the figure When the microcont...[Details]

As people's living standards improve, their requirements for living environment are getting higher and higher. What people are particularly concerned about in the home environment are the pollution o...[Details]

1. Consult relevant information and complete the schematic design; 2. Write software so that the system can output square wave, triangle wave, sawtooth wave and trapezoidal wave; the waveform frequen...[Details]

1 Introduction Data acquisition and monitoring have become increasingly important detection technologies in scientific research and various other fields. In many industrial me...[Details]

STM32 hardware I2C debugging is indeed much more troublesome than simulation. There are a lot of configurations. I debugged the F series. I thought it would be easy to directly port to the L series, ...[Details]

Instead of JTAG debugging, use SW debugging, so that you can save a few IOs for use as ordinary IO. PA15, PB3, and PB4 can be saved as common IO. method: RCC_APB2PeriphClockCmd(RCC_APB2Periph_AFIO,EN...[Details]

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]
