The External Interrupt of single-chip microcomputer has also been enhanced by other single-chip microcomputer, which is not triggered by a simple descent edge. Currently, high and low level triggering is triggered, and the rising edge and falling edge are triggered, more level changes are triggered. At present, the development is basically complete, and the external interrupt function is very great. It can

You can see usart in many data manuals. UART, SPI, IIC, USB, and CAN communication are messy. You know this is sharp. Serial Communication, there are data formats and data transmission rates. At present, many single-chip computers have UART, especially 51 in our university, which is everywhere on the network. So if I think about it, I will also flood it, or I will forget it later, haha. 51 The serial communication is relatively simple. Set the transmi

I can see this question. A lot of people may need to hit the stone brother's board. What is the value of 7 + 5? How do you teach this? But in single-chip microcomputer, numbers are used Binary representation: This is just a bit of a logging/ Even though we have not learned a command for teaching materials. However, I mean to do a few experiments first to increase your interest in single chip microcomputer.

The timer is a very important function for each MCU. To implement a precise timer, measure the frequency, and generate a PWM, the timer depends on the timer. The number of timer digits determines the timer precision, currently, we have encountered an 8-bit timer, a 16-bit timer, and a 32-bit timer. Features are more powerful than others. The higher the number of digits, the higher the accuracy of PWM, the more delicate the changes, easy to control. For at89x51, there are two timers T0 and T1, An

51. 52 single-chip microcomputer matrix keyboard, 5152 single-chip microcomputer Matrix To learn about the matrix keyboard, first make a small experiment: After you press the matrix keyboard, the digital display displays the number of keys that are pressed. My matrix keyboard is 4x4. The operating principle is to first check which line of key is pressed. Then determine the column. In this way, you can ident

Flash has the characteristics of power-down data storage. If Ram power-down occurs, data is lost, but Ram speed is higher. Theoretically, there is no limit on the number of writes, But Flash does not.Compared with other types of flash, NAND Flash has the advantage of high erasability and high write speed. However, Bad blocks may occur during use and use.Can be used only after processing. It is mainly used for data storage, and most USB flash drives are NAND Flash.Nor flash read/write timing is s

The third part of this series mainly introduces the implementation details of the Skyeye hardware simulation platform. The main content includes the overall design of Skyeye, the Scalable framework of Skyeye, the key data structure of Skyeye, the simulation implementation of Skyeye on various CPUs, the simulation implementation of Skyeye on various peripherals, and how to install and use Skyeye and how to expand the simulation module of Skyeye. An in-depth understanding of Skyeye helps to gain a

1. Dip dual-row direct insert Encapsulation Dip (dualin-line package) is an integrated circuit chip encapsulated in the form of Dual-row direct insertion. Most small-and medium-sized Integrated Circuits (IC) use this encapsulation form, generally, the number of pins cannot exceed 100. The CPU chip in dip package has two pins and needs to be inserted into the chip
