NIOS II 的几个源代码，读SD卡、直流电机的转速调节、简易数字示波器、简易频谱分析仪、USB文本阅读器,NIOS II several source code, read SD cards, the speed regulation of DC motor, simple digital oscilloscope, spectrum analyzer summary, USB version of Reader

读SD卡，主要涉及SOPC技术，NIOS软核编程，供学习参考用-Reading SD card, mainly related to SOPC technology, NIOS soft-core programming for the study and reference

在ALTERA的DE2板子上做的一个读写SD卡的例子，基于QUARTUS II ,SOPC BUILDER ,Nios II IDE实现的，从SD卡读写东西-The DE2 board in ALTERA do an SD card reader example, based on the QUARTUS II, SOPC BUILDER, Nios II IDE achieved something from the SD card reader

用C语言写的SD卡读写程序，含MP3文件读取与播放，硬件平台伟NIOS2，FPGA-Written in C program the SD card reader, with read and play MP3 files, hardware platforms Wei NIOS2, FPGA
