哈弗曼编码的实现，本人亲测完美运行。 编码内容：假设用于通信的电文仅由8个字母组成，字母在电文中出现的频率分别为7，19，2，6，32，3，21，10。试为这8个字母设计哈夫曼编码。 要求：这8个字母任意，输出各字母的编码值。 -huffman Tree

基于DS18B20温度传感器的设计程序 要求为：第一，由DS18B20获得外部温度信息然后通过数码管显示，显示值为三位，两位整数，一位小数。第二，判断温度是否大于 50℃，若温度在50℃以上，显示红色发光二极管发光；若温度在50℃以下，显示绿色发光二极管发光。-DS18B20 temperature sensor based on the design of procedural requirements: first, by DS18B20 access to external temperature information through a digital display, showing a value of 3, two integer, a decimal. Second, to determine whether the temperature is greater than 50 ℃, if the temperature at 50 ℃, which indicates that the red light-emitting light-emitting diodes if the temperature below 50 ℃, showing a green light-emitting diode LED.
