OXCC is a multipass, interpreting C compiler with several language extensions. It generates an Architecture Neutral Format (ANF) output and comes with a couple of example back ends. Programmers are expected to write additional back ends for their specific needs.

该词法分析程序用VC++ 6.0编写,以FileOpenDialog打开的*.c或*.cpp文件为语言字集的源程序作为词法分析程序的输入数据,经词法分析程序分析后的结果保存在源文件的同目录的output.txt文件中。在词法分析中,自文件头开始扫描源程序字符,一旦发现符合“单词”定义的源程序字符串时,将它翻译成固定长度的单词内部表示,并查填适当的信息表。经过词法分析后,源程序字符串(源程序的外部表示)被翻译成具有等长信息的单词串(源程序的内部表示),并产生两个表格:常数表和标识符表,它们分别包含了源程序中的所有常数和所有标识符。

LVQ学习矢量化算法源程序 This directory contains code implementing the Learning vector quantization network. Source code may be found in LVQ.CPP. Sample training data is found in LVQ1.PAT. Sample test data is found in LVQTEST1.TST and LVQTEST2.TST. The LVQ program accepts input consisting of vectors and calculates the LVQ network weights. If a test set is specified, the winning neuron (class) for each neuron is identified and the Euclidean distance between the pattern and each neuron is reported. output is directed to the screen.

This project is created using the Keil ARM CA Compiler. The Logic Analyzer built into the simulator may be used to monitor and display any variable or peripheral I/O register. It is already configured to show the PWM output signal on PORT3.0 and PORT3.1 This ARM Example may be debugged using only the uVision Simulator and your PC--no additional hardware or evaluation boards are required. The Simulator provides cycle-accurate simulation of all on-chip peripherals of the ADuC7000 device series. You may create various input signals like digital pulses, sine waves, sawtooth waves, and square waves using signal functions which you write in C. Signal functions run in the background in the simulator within timing constraints you configure. In this example, several signal functions are defined in the included Startup_SIM.INI file.

This example program shows how to configure and use the A/D Converter of the following microcontroller: STMicroelectronics ST10F166 After configuring the A/D, the program reads the A/D result and outputs the converted value using the serial port. To run this program... Build the project (Project Menu, Build Target) Start the debugger (Debug Menu, Start/Stop Debug Session) View the Serial Window (View Menu, Serial Window #1) View the A/D converter peripheral (Peripheral Menu, A/D Converter) Run the program (Debug Menu, Go) A debug script (debug.ini) creates buttons that set different analog values in A/D channels. As the program runs, you will see the A/D input and output change. Other buttons create signals that generate sine wave or sawtooth patterns as analog inputs. µ Vision3 users may enable the built-in Logic Analyzer to view, measure and compare these input signals graphically.

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.
