本文只有程序，无电路图，是基于单片机控制的线性数字稳压电源-In this paper, only the procedures, no circuit diagram is based on the number of single-chip control of linear regulated power supply

ps2键盘的命令集，编写键盘驱动时有用。EDH:置位/复位 LED 指示器。键盘右上角有三个 LED 指示器,分别反映 Caps、Num 和 Scroll 三个键的 锁定情况。参数字节如表 2 所列。 -ps2 keyboard command set, the preparation of useful keyboard-driven. EDH: Set/reset LED indicator. The upper right corner of the keyboard has three LED indicators, respectively, reflecting the Caps, Num and Scroll Lock keys in three cases. Parameter bytes as listed in Table 2.

万年历程序，用8563和ZLG7290及51单片机做的，库函数可以去ZLG下载-hefty almanac procedures, and using 8563 Wire and 51 SCM do, library functions can be downloaded to ZLG

MSP430 F149的单片机 液晶驱动程序，便于相应计时器的操作-Microcontroller MSP430 F149 LCD driver for the operation of the corresponding timer

这是一套基于单片机的温湿度测量系统，里边附有设计的原理图，pcb图，以及烧写程序代码（keil c51编写的）。温湿度传感器使用的是dht11，性价比高。该系统除了能显示温湿度以外，还能设置温湿度报警阈值。设计的pcb板，小巧，使用。这是本人的毕业设计，有实物为依据，具有可操作性。-This is a single-chip microcomputer-based measuring system of temperature and humidity inside with schematic design, pcb plans, as well as the programmer code (keil c51 prepared). Temperature and humidity sensors are used dht11, cost-effective. Except that the system can display temperature and humidity outside, but also set the temperature and humidity alarm threshold. Pcb board design, compact, use. This is my graduation project, there is the physical basis of operational.

DESCRIPTION =========== This example project shows how to use the IAR Embedded Workbench for ARM to develop code for the Atmel AT91SAM9261 evaluation boards. It shows basic use of parallel I/O, timer and the interrupt controller. It starts by showing different patterns on the LED s separated by half second. COMPATIBILITY ============= The project is compatible with the AT91SAM9261-EK board.
