Description: Genie-shell for ucos
一、 基本要求（必做）
（1） 设计并实现ucos的shell模型
（2） 实现简单的Shell命令
hostname命令在屏幕上打印一句话，即自定义的本机名称。
hello 命令可以带多个参数，如hello a b c d，回车后会显示：
hello，I am Genie
your argv is：
a
b
c
d
（3）实现在串口和LCD的同步显示，即所有的命令操作过程都要显示在串口和LCD上。
二、 提高要求（选做）
自己设计几条新的命令，比如输入time即可显示时间，输入data即可显示日期或者可以通过命令设置时间和日期等。
-Genie- shell for TRACK 1, basic requirements (regimen) (1) design and implement CENTER shell model (2) to achieve a simple Shel l command hostname command on the screen print a word that is, since the definition of the machine name. Hello orders can take a number of parameters, such as hello a b c d, Enter will show : hello, I am your argv Genie is : a b c d (3) Achieve the serial synchronous and LCD display, that is, all the orders must show that the process of the serial and LCD. Two, raising requirements (election so) designed several new orders, such as the importation of time will be shown, input data can indicate the date or can be ordered through the set-up time and date.

Description: 软件A/D所能实现的精度有限，测量电压范围是2-15V，
而且速度低(约1KHz),但仅用一个电容和一个电阻的诱惑
力，我想大虾您会笑纳的。用于某些场合是有用的。
原理是利用470K电阻对1uF电容充电，利用P0.0口作为检测电压，
当电压低于1/3 VCC时，P0.0读入的I/O电平为0，当充电电压超过
1/3 VCC时，P0.0读入的I/O电平为1。通过测量此过程所用的时间，
就能判断输入电压（需要换算）。
程序的编写用定时器0实现-Software A/D can achieve the accuracy is limited, measuring voltage range is 2-15V, and low-speed (approximately 1 KHz), but only a capacitance and resistance of a temptation, I think you will prawns to the heart. For certain occasions is useful. The principle is the use of 470 K resistor pairs .1 uF capacitor charging, as I use P0.0 detection voltage, When the voltage is lower than 1/3 VCC, P0.0 read into the I/O level to 0, When the charging voltage over 1/3 VCC, P0.0 read into the I/O level to 1. By measuring this process, the time spent, we will be able to judge the input voltage (need conversion). The preparation procedures used to achieve timer 0

Description: 同诸多网友一样，受益于VCKBASE，觉得应为他做点贡献了，于是做了这么一个基于表达式求值的科学计算器与各位爱好编程的朋友分享。
如您所知，这方面的程序很多，看过ZF.Yi的相关作品，也见过黄江峰的相关程序，但我觉得我的计算类有不同于二位的特色，如计算结果的有效位较长（16位）；支持不严格的表达式输入（如cos(23)*sin(34)与cos(23)*sin(34与cos23*sin34等价）；支持四种进制的数在一个表达式中同时出现的进制混合运算（除十进制外的各进制数不限于整数，如12d.3axh，xh是我的计算类所能识别的十六进制数的标识符）；且程序做得也比较精细（如制作了鼠标键盘、窗口跟随、计算历史查看等），这才使我觉得拙作不致于滥竽充数，相信网友们看了会另有收获的。-with many netizens, benefited from VCKBASE, think he should Zuodiangongxian. So do so based on a formula that evaluates the scientific calculator with you-loving friends to share programming. As you know, many of the procedures, ZF.Yi read the relevant works have seen Huang Jiang-related procedures, But I think I kind of calculation is different from the two characteristics, such as the results of a longer-effective (16); support rigorous expression input (such as cos (23)* sin (34) cos (23)* sin (34 with the equivalent sin34 cos23*); supports four 229 in a few expressions while the 229 mixed Operators (except outside the decimal 229 is not limited to a few Integer, 12 d.3axh, the exposure is calculated effort to identify the type hexadecimal number identifier); and procedures done rela
