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.

這個(gè)例子如果運(yùn)行,將在仿真的PC窗口中的第1,2,3行顯示一些信息后,在隨機(jī)位置顯示 1 ~ 5 .由于keil c51默認(rèn)不支持重入函數(shù),它的重入函數(shù)使用仿真的重入棧而不使用系統(tǒng)棧,而Small RTOS 51沒(méi)有進(jìn)行重入棧管理,所以在TaskA~TaskE雖然及其相似,但不能合并. 注意:(1)在KEIL C51 工程中,我已經(jīng)把輸出文件目錄設(shè)在e:\temp中,您可以在Project->Options for Target "Target 1"的output頁(yè)點(diǎn)擊Select Folder for Objects...和Listing頁(yè)點(diǎn)擊Select Folder for Listing...改變. (2)編譯時(shí)會(huì)有5個(gè)警告,其中一個(gè)是因?yàn)闆](méi)有使用一個(gè)系統(tǒng)函數(shù)OSSendSignal引起,它可以忽略.另4個(gè)是禁止任務(wù)間變量覆蓋分析引起,必須忽略.感謝網(wǎng)友John X.

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

Included are the files wav1.m, wav2.m, wavecoef.mat and readme. wav2 function implements the tree structured wavelet transform of the input matrix, up to the given level of decomposition. Wav2 uses another function called wav1, which takes the well known wavelet transform of the given matrix. Daubechies wavelet coefficients are used for wavelet transform operation wahich is saved in wavcoeff.mat.
