嵌入式系统课堂笔记。。。使用三星的开发版本。。。主要是ARM指令集

vivi的源代码,是在linx下的才能使用的,是三星2410上的好东西哦-anger of the source code is under the linx can use, Samsung 2410 on the good things oh

本程序为我们参加第四届飞思卡尔全国大学生智能汽车竞赛的源代码,较好的解决了路径识别的问题. 开发环境:CodeWarrior 4.5 芯片:mc912dg128-This procedure for us to participate in the Fourth National University Freescale Smart car racing" s source code, the better solution of the path identify the problem. Development environments: CodeWarrior 4.5 Chip: mc912dg128

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.
