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 subject which is to us propos¨¦ is as follows: calculation of the degr¨¦ d¡ ¯ inconsistance d¡ ¯ un logical program possibilist in C++. We thus work on a logical program possibilist, it be-¨¤-statement a logical program resulting from non-classique logic. The goal First of this project is of d¨¦ terminer if a logical program is consisting or not of share the calculation of sound degr¨¦ d¡ ¯ inconsistance.
The tar file contains the following files:
ptfsf.c: heart of the perfect TFSF code
ptfsf.h: header file for same
ptfsf-demo.c: FDTD code which demonstrates use of perfect TFSF code. Essentially this program used to generate results shown in the paper
ptfsf-file-maker.c: code to generate an incident-field file using the "perfect" incident fields
ptfsf-demo-file.c: FDTD code which uses the perfect incident fields stored in a file
fdtdgen.h: defines macros used in much of my code
Makefile: simple make-file to compile programs
Also include are some simple script files to run the programs with reasonable values.
The code assumes a two-dimensional computational domain with TMz polarization (i.e., non-zero field Ez, Hx, and Hy). The program is currently written so that the incident field always strikes the lower-left corner of the total-field region First. (If you want a different corner, that should be a fairly simple tweak to the code, but for now you ll have to make that tweak yourself.)
uc/os-ii for 8051
This package provides the sources required to use the uC/OS-II v2.00
real time kernel on the 8051 processor. To use this package you will
need the TASKING C Compiler toolset v6.0r1 or higher.
For info on TASKING products you can contact our Web-site at:
http://www.tasking.com
Unzip the zipfile in the root of the drive where you also installed
the uC/OS-II general sources. The following directories will be
added:
\SOFTWARE\UCOS-II\8051
This directory contains the microprocessor specific source code
\SOFTWARE\UCOS-II\ex1_8051r
This directory contains the project files for the First example
\SOFTWARE\UCOS-II\ex2_8051r
This directory contains the project files for the second example
This zip file shows the use ROM Services in order to speed up an application and reduce its code size. It shows how to load a method of the Xmodem service and obtain a First level bootloader. Includes main.html file for help.
Decoding most of the infrared signals can be easily
handled by PIC16C5X microcontrollers. This application
note describes how this decoding may be done.
The only mandatory hardware for decoding IR signals
is an infrared receiver. The use of two types is
described here. Both are modular types used often by
the consumer electronics industry. The First type
responds to infrared signals modulated at about
40 kHz. The second responds to non-modulated infrared
pulses and has a restricted range. The hardware
costs of each approach will be less than two dollars.
經(jīng)典著作《設(shè)計模式》中將策略模式定義為：定義一系列的算法，把它們一個個的封裝起來，并且使它們可以相互轉(zhuǎn)換。這個定義還是比較抽象，下面我將通過一個例子來具體的講解策略模式。感覺這樣更容易幫助新手理解模式，這也是《Head First Design Patterns》中講解模式的方法。先來描述一下用到的例子的背景資料：
MFC Black Book
Introduction:
Are you an MFC programmer? Good. There are two types of MFC programmers. What kind are you? The First kind are the good programmers who write programs that conform to the way MFC wants you to do things. The second bunch are wild-eyed anarchists who insist on getting things done their way. Me, I’m in the second group. If you are in the same boat (or would like to be) this book is for you.
This book won’t teach you MFC—not in the traditional sense. You should pick it up with a good understanding of basic MFC programming and a desire to do things differently. This isn’t a Scribble tutorial (although I will review some fundamentals in the First chapter). You will learn how to wring every drop from your MFC programs. You’ll discover how to use, abuse, and abandon the document/view architecture. If you’ve ever wanted custom archives, you’ll find that, too.
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.
