一个好文件,是关于RS232与RS485的区别的介绍-a good document, on the RS232 and RS485 differential introduced

PDF417二维条码是一种堆叠式二维条码，目前应用最为广泛。PDF417条码是由美国SYMBOL公司发明的， PDF（Portable Data File）意思是“便携数据文件”。组成条码的每一个条码字符由4个条和4个空共17个模块构成， 故称为PDF417条码。 PDF417条码需要有417解码功能的条码阅读器才能识别。PDF417条码最大的优势在于其 庞大的数据容量和极强的纠错能力。

随着各行各业的发展和生产需要，业界上的采集器已经满足不了某些行业的生产需要，他们不仅需要采集数据还需将数据发生变化的时间记录下来，断电数据不掉失，特别是当电脑读取采集器的数据时还需能继续采集数据，保证不掉失一个数据，并且还要求擦除采集器旧的数据时还能继续采集数据和保存数据，保证不擦除新的数据，因为某些场合需要时时刻刻不间断的采集数据，并要求任何时刻都能读取数据。 他们迫切地需要一种新的多功能的，并且能够多通道采集数据的采集器。 -With the development and production of all walks of life needs of the industry on the collector has been unable to meet the needs of certain sectors of production, they require not only data collection will need to change the time data recorded, the data can not lose power, especially is when the computer read the data collector can continue to collect data needed to ensure that a data can not lose, and also requires the collector erase the old data will continue to collect data and save data to ensure that does not erase the new data, because some occasions the need for uninterrupted data collection at all times and request at any time be able to read data. They urgently need a new multi-functional, and can multi-channel acquisition data collector.

FFT算法的DSP实现,不用多说了，对于做fft的人非常有参考价值。呵呵，希望对大家都有用处。-FFT algorithm of DSP realize, goes without saying, for to do fft are very valuable reference. Ha ha, I hope useful to everyone.

内容比较早，但写得较底层，包括bios,分区有等操作都的介绍，一共是两个文件pdf格式，应该有200多个源码《C语言编程实例》-Contents earlier, but well-written than the bottom, including bios, partition and other operations are the introduction there are a total of two files pdf format, there should be more than 200 source " C Language Programming Example"
