The LT® 1529/LT1529-3.3/LT1529-5 are 3A low dropout regulators with micropower quiescent current and shutdown. The devices are capable of supplying 3A of output current with a dropout voltage of 0.6V. Designed for use in battery-powered systems, the low quiescent current, 50mA operating and 16mA in shutdown, make them an ideal choice. The quiescent current is well controlled it does not rise in dropout as it does with many other low dropout PNP regulators.

这个例子如果运行,将在仿真的PC窗口中的第1,2,3行显示一些信息后,在随机位置显示 1 ~ 5 .由于keil c51默认不支持重入函数,它的重入函数使用仿真的重入栈而不使用系统栈,而Small RTOS 51没有进行重入栈管理,所以在TaskA~TaskE虽然及其相似,但不能合并. 注意:(1)在KEIL C51 工程中,我已经把输出文件目录设在e:\temp中,您可以在Project->Options for Target "Target 1"的output页点击Select Folder for Objects...和Listing页点击Select Folder for Listing...改变. (2)编译时会有5个警告,其中一个是因为没有使用一个系统函数OSSendSignal引起,它可以忽略.另4个是禁止任务间变量覆盖分析引起,必须忽略.感谢网友John X. Liu,在这个例子中我使用了他编写的仿真(dllPc51Emu.dll),这个dll原来是为他移植的Ucos-ii for keil c51的例子编写. (3)Pc51Emu.dll在KEIL C51 V6.23 V7.00工作不正常.

这个例子是例子2的另一种写法（但任务数量不同）,它使用了最高优先级任务作为显示任务,全局变量ShowChar作为参数.函数TaskB是优先级1~10的任务函数,因为没有使用局部变量,这些任务可以用一个函数. 注意:(1)在KEIL C51 工程中,我已经把输出文件目录设在e:\temp中,您可以在Project->Options for Target "Target 1"的output页点击Select Folder for Objects...和Listing页点击Select Folder for Listing...改变. 感谢网友John X.

Frequency Scale Conversion From f To f Scale frq2mel mel2frq mel The mel scale is based on the human perception of sinewave pitch. frq2erb erb2frq erb The erb scale is based on the equivalent rectangular bandwidths of the human ear. frq2midi midi2frq midi The midi standard specifies a numbering of semitones with middle C being 60. They can use the normal equal tempered scale or else the pythagorean scale of just intonation. They will in addition output note names in a character format.

The government of a small but important country has decided that the alphabet needs to be streamlined and reordered. Uppercase letters will be eliminated. They will issue a royal decree in the form of a String of B and A characters. The first character in the decree specifies whether a must come ( B )Before b in the new alphabet or ( A )After b . The second character determines the relative placement of b and c , etc. So, for example, "BAA" means that a must come Before b , b must come After c , and c must come After d . Any letters beyond these requirements are to be excluded, so if the decree specifies k comparisons then the new alphabet will contain the first k+1 lowercase letters of the current alphabet. Create a class Alphabet that contains the method choices that takes the decree as input and returns the number of possible new alphabets that conform to the decree. If more than 1,000,000,000 are possible, return -1. Definition
