Proteus仿真ARM7的几个经典例子

函数发生器是一种在科研和生产中经常用到的基本波形产生器，集成函数 波形发生器一般都采用ICL8038或5G8038，而它们只能产生300kHz以下的中低频正弦波、矩形波和三角波，且频率与占空比不能单独调节，从而给使用带来很大不便。本文介绍由LM324和稳压管组成的低频函数波形发生器，该电路能够产生正弦波、方波和三角波信号，频率能以10Hz的间隔在20Hz～20KHz范围内调整。-Function Generator is a scientific research and production often use the basic waveform generator, integrated function waveform generator usually used ICL8038 or 5G8038, and they only have a 300kHz following the low-frequency sine wave, square wave and triangular wave, and frequency and duty cycle alone is not regulated, so as to enable using bring a lot of inconvenience. This paper introduces the LM324 voltage regulator tubes, and the low-frequency waveform generator function, the circuit can produce sine, square and triangular wave signal frequencies of 10Hz to 20Hz at intervals within ~ 20KHz adjustment.

完整VC6.0编写的的三菱PLC上位机编程软件源码，以及DebugPLCEDIT。对于程序员而言，具有很好的参考利用价值。

DE2_NET ------- This designs demonstrates how to use the Ethernet port using a Nios II system on the DE2 board. It sends packets, and using a loopback Ethernet cable, it"ll receive the same packets which are then displayed. It also works if the board is connected to another packet source. Running the Design ------------------ 1) Launch the Quartus II software. 2) Open the DE2_NET.qpf project located in the DE2_NET folder.
