AVR单片机入门及C语言高效设计实践(13)源程序码

利用mega16自带的AD进行电压测量.测量范围0~5V.-Mega16 own use of the AD for voltage measurement. Measuring Range 0 ~ 5V.

用于单片机的开发 用modbus协议 实现上位机与下位机的通讯-design for mcu,protocl is modbus,for double mcu commiunication

Atmel SPI slave C51程序-Atmel SPI slave C51 procedures

这个范例说明如何使用8051 的Port 1连接LCD显示器，PORT 3.3、P3.4和P3.5则连接到LCD显示器的控制线。程序执行时将显示出Hello Keil C和LCD display */-This example shows how to use the 8051 Port 1 to connect LCD displays, PORT 3.3, P3.4 and P3.5 are connected to the LCD display control lines. Program execution will show Hello Keil C, and LCD display* /

89c51详细介绍-89c51 in detail introduced

自行开发的51单片机电子钟程序，且带有上位机通讯的功能。-self-developed electronic bell 51 SCM procedures and communication with PC functions.

24c04读写程序，同时控制p10口的打开和关闭-24c04 read and write procedures for control of p10 at the same time the mouth opened and closed

按键扫描 51单片机加8279 8279通过74LS 138译码器扩展4×4键盘、6位显示器。 由3-8译码器对SL0～SL2译出键扫描线，由另一3-8译码器译出显示器的位扫描线，并采用了编码扫描方式。 为了防止出现重键现象，扫描输出线高位SL3不参加键扫描译码。CPU对8279的监视采用了查询方式，故8279的中断请求信号IRQ悬空未用。 -Scan button 82,798,279 plus 51 single-chip decoder 74LS 138 through the expansion of 4 × 4 keyboard, the display 6. From 3-8 decoder SL0 ~ SL2 translated to the key scanning line, by another 3-8 decoder translated display scan line, and uses code scanning. In order to prevent the emergence of the phenomenon of re-key, scan the output line does not take part in high level SL3 scan decoding keys. CPU on the 8279 surveillance using the query mode, the 8279 interrupt request signal IRQ left unused.

SY1126开发板测试程序。 51系例单片机的最小系统 有AT89S8252/AT89S51/52的在线下载功能 IIC总线芯片为24C02,记存密码-SY1126 development board test procedure. Example 51 Department of the smallest single-chip systems have AT89S8252/AT89S51/52 online download function for IIC bus chip 24C02, keep password
