small rtos for avr small rtos 使用了动态堆栈 想无需任何改动就可以编译这个程序，就必须安装winavr20050214和uv2,先点击uv2的工程文件打开这个工程然后在Tools---->Customize Tools Menu...嵌入gcc编译命令make all和make clean即可立即编译。编译后可以使用avr studio进行代码级仿真-small Byelorussian for avr small Byelorussian use of dynamic stack without any changes to be compiled for the process, it must be installed and uv2 winavr20050214, first click uv2 works documents before the project opened in Tools- gt; Customize Tools Menu ... embedded gcc compiler make all orders and instantly make clean compile. Compiled avr studio can be used for code-level simulation

基于ATmega8的数控电源 包括显示 扫描 转换等详细的源程序-NC-based ATmega8 power, including details such as display scan conversion source

在外部环境中检测亮度，温湿度，其中带232及485控制-Detected in the external environment brightness, temperature and humidity, which with 232 and 485 control

键盘测试程序，包括显示 、去抖动、扫描、检测，（8051或8031）-keyboard testing procedures, including, to jitter, scanning, detection, (8051 or 8031)

数字温度计进而考虑到用温度传感器，在单片机电路设计中，大多都是使用传感器，所以这是非常容易想到的，所以可以采用一只温度传感器DS18B20，此传感器，可以很容易直接读取被测温度值，进行转换，就可以满足设计要求。-Digital thermometer to take into account the use of temperature sensors, in single-chip circuit design, most of them are the use of sensors, so it is very easy to think of, so can use a temperature sensor DS18B20, this sensor can easily be directly read measured temperature values, the conversion, it can meet the design requirements.
