RISC gives priority to the most frequently used simple instructions and avoids complex instructions. It also fixes the instruction width, reduces the types of instruction formats and addressing modes...[Details]

1. DMA principle: DMA (Direct Memory Access) is an important feature of all modern computers. It allows hardware devices of different speeds to communicate without relying on a large interrupt load o...[Details]

　　There are three 8-bit input/output ports on the main processor ATMega328P of Arduino UNO R3, namely PB, PC and PD. The Blink example provided by Arduino IDE can help us understand the digital outpu...[Details]

Reference: "STM32F4xx Chinese Reference Manual" RCC chapter. The STM32 clock can be roughly divided into two categories: system clock and other clocks, including a total of 5 clock sources: HSI (Hi...[Details]

Preface 　　Recently, when debugging the STM32F2XX series ADC multi-channel DMA acquisition, I found that the collected AD value was greater than 4095, and some were more than 65000. What's the rhythm?...[Details]

1 Introduction When using electronic components, you must first understand its parameters. Resistors have resistance values ​​and capacitors have capacitance values. This requires the ability to a...[Details]

1 Overview Scanning probe microscopy (STM) is the most important tool in the development of nanotechnology. It is based on the tunnel penetration theory in quantum mechanics. Its core is a nee...[Details]

At the beginning of the program, the timer and interrupt registers need to be initialized: Assign values ​​to TMOD, the timer/counter operating mode register, to determine the operating mode of T0 a...[Details]

As can be seen from the figure, the analog ADC is divided into two parts, one is the touch screen function, and the other is the ordinary ADC function. Two interrupts, INT_TC and INT_ADC, can...[Details]

In recent days, I need to use stm32 to count external input pulses, and I naturally think of the timer. However, the information I have does not explain how to use the stm32 timer as an external coun...[Details]

8031/8051/8751 are early products of Intel. 1. Characteristics of 8031 The 8031 ​​chip does not have a program memory ROM. When using it, the user needs an external program memory and a logic cir...[Details]

When we really want to use the PID algorithm, we find that it is not so easy to implement the code in the book on our 51. Simply put, it cannot be called directly. A careful analysis will r...[Details]

ADC Introduction:     ADC (Analog-to-Digital Converter). That is, converting analog signals into digital signals for processing. When storing or transmitting, analog-to-digital converters are almost ...[Details]

With the continuous advancement of hydrological modernization, water regime monitoring and reporting as an important means of hydrological work is also developing rapidly. Water regime monitoring a...[Details]

Liquid crystal display (LCD) has many advantages that other displays cannot match, such as low power consumption, small size, light weight, and ultra-thinness. In recent years, it has been widely u...[Details]
