該詞法分析程序用VC++ 6.0編寫,以FileOpenDialog打開的*.c或*.cpp文件為語言字集的源程序作為詞法分析程序的輸入數(shù)據(jù),經(jīng)詞法分析程序分析后的結果保存在源文件的同目錄的output.txt文件中。在詞法分析中,自文件頭開始掃描源程序字符,一旦發(fā)現(xiàn)符合“單詞”定義的源程序字符串時,將它翻譯成固定長度的單詞內(nèi)部表示,并查填適當?shù)男畔⒈怼=?jīng)過詞法分析后,源程序字符串(源程序的外部表示)被翻譯成具有等長信息的單詞串(源程序的內(nèi)部表示),并產(chǎn)生兩個表格:常數(shù)表和標識符表,它們分別包含了源程序中的所有常數(shù)和所有標識符。

This directory contains the memtest 8051 firmware for the Anchor Chips EZ-USB chip. The purpose of this software is to test the different memory segments in the Ez-Usb chip. This example will output the string "good" on the 7 segment LED if the mem test passes, or it will output the first address where the memtest fails.

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.

這個例子如果運行,將在仿真的PC窗口中的第1,2,3行顯示一些信息后,在隨機位置顯示 1 ~ 5 .由于keil c51默認不支持重入函數(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沒有進行重入棧管理,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)把輸出文件目錄設在e:\temp中,您可以在Project->Options for Target "Target 1"的output頁點擊Select Folder for Objects...和Listing頁點擊Select Folder for Listing...改變. (2)編譯時會有5個警告,其中一個是因為沒有使用一個系統(tǒng)函數(shù)OSSendSignal引起,它可以忽略.另4個是禁止任務間變量覆蓋分析引起,必須忽略.感謝網(wǎng)友John X. Liu,在這個例子中我使用了他編寫的仿真(dllPc51Emu.dll),這個dll原來是為他移植的Ucos-ii for keil c51的例子編寫. (3)Pc51Emu.dll在KEIL C51 V6.23 V7.00工作不正常.

這個例子是例子2的另一種寫法(但任務數(shù)量不同),它使用了最高優(yōu)先級任務作為顯示任務,全局變量ShowChar作為參數(shù).函數(shù)TaskB是優(yōu)先級1~10的任務函數(shù),因為沒有使用局部變量,這些任務可以用一個函數(shù). 注意:(1)在KEIL C51 工程中,我已經(jīng)把輸出文件目錄設在e:\temp中,您可以在Project->Options for Target "Target 1"的output頁點擊Select Folder for Objects...和Listing頁點擊Select Folder for Listing...改變. 感謝網(wǎng)友John X.
