This was originally a question I did in my junior year. It was an out-of-class exercise. In the single-chip microcomputer course, an experiment is to control the digital display of a clock. The program logic is very simple and can be expressed by

# Include typedef unsigned char uchar; typedef unsigned int uint; # define rs_h PORTC | = 0x01 # define rs_l PORTC & = 0xfe # define rw_h PORTC | = 0x02 # define rw_l PORTC & = 0xfd # define en_h PORTC | = 0x04 # define en_l PORTC & = 0xfb # define

# Include "typedef. H"# Include "digitaltube. H"# Include "interrupt. H" Sbit led0 = P0 ^ 0; // set bandwidth limit to µ¥ bandwidth limit» úµäp0 limit to μäµúbandwidth bandwidth»Sbit led1 = P0 ^ 1; // é ù ã µ {µ¥ {}» úµäp0 ~úµäµú?¶ þ î»Sbit led = P0;

Use the timer of the STC single-chip microcomputer to perform a scheduled task of 1 second, 1 minute, and 1 hour. Because I use 11.0592 crystals, the time is not very accurate. If you have precise timing requirements, use a m crystal oscillator. The

After the basic functions of the system clock generator are established, the scg1, scg0, cpuoff, and oscoff bits of the SR in the CPU are important low-power control bits. As long as any interrupt is responded, the above control bit is pushed into

The size of my color screen is 240*320 ~The following code is used: //common.h#ifndef __COMMON_H__#define __COMMON_H__#include #include typedef unsigned int uint;typedef unsigned char uchar;#endif// !__COMMON_H__ // Touchpad. C # DEFINE _ touchpad_c

  The coordinates of many points are given and covered with the smallest square. Question: three points. Pay attention to precision ····. Draw a diagram of the formula Shenma to solve the problem. Double mid1 = (left + right)/2; Double mid2 = (mid1 +

To achieve human-computer interaction, the display device is indispensable. Previously, I talked about how to use a single-chip microcomputer to control the display of digital tubes. This article focuses on how to control the LCD display and adds

What is jin51sio? Jin51sio is a program that automatically generates a single-chip serial communication operation function set. Jin51sio is an API function set for single-chip microcomputer serial port operations.     What does jin51sio2 contain? 1.

NOP null Operation Command Syntax: NOP Operand: None Execution time: one instruction cycle Execution Process: Except for consuming one instruction cycle, it has no impact. Therefore, it is usually used as a delay. Status flag impact: None Note: The

Add the content of the addwf W register and the content of the f Data Register Syntax: addwf F, d Operand: F is the low 7-bit address of the data register (0x00 ~ 0x7f) D is the low 7-bit address of the destination register (0x00 ~ 0x7f) When d = F,

Bit operation instructions BCF data register refers to locating 0 Syntax: bcf f, B Operand: F is the low 7-bit address of the data register (0x00 ~ 0x7f) B is the data bit number (0 ~ 7) Execution time: one instruction cycle Execution Process: Clear

I believe that, as a beginner of stm32, everyone is learning by downloading routines from the official website. Now firmwave's latest version is 1.1.0, for http://www.st.com/stonline/stappl/resourceSelector/app? Page = resourceselector & doctype =

In the actual application of RFID, due to the large data volume, the customer needs to occupy multiple sectors and blocks. In the previous interface, only one block can be read for one interaction. When the data volume is large, interaction takes a

Single-chip microcomputer is not difficult programming problems! URGENT!!!!!! Converts the 8-bit binary number in the R0 to 3-bit BCD, resulting in a 1002h~1000h (from high to low) unit of external RAM. For example: At the beginning, the data in the

ARM Cortex-M Processor family is an energy-efficient and easy-to-use family of compatible processors designed to help developers meet the needs of future embedded applications.
