Description: 2007年全国大学生电子设计大赛,A题音频信号分析仪的全部源程序。
单片机为c8051f120,系统时钟倍频至96MHZ。
main.c是一个包含五级菜单的主函数。
FFT.C是进行fft变换,将时域信号变换成频域信号。
flash.c是读写片外flash存储器的程序,可以将分析结果保存,以备调用.
z7290.c是周立功7290键盘芯片的驱动程序.
FFT_xgjis.c是对变换后的频谱进行分析和运算.
FFT_CodeTable.c是一个正弦表,在FFT的时候调用.
LCD320240.c是320*240的液晶驱动程序,液晶的控制器是SED1335.
所有的.h文件提供了子函数的定义.
本程序用KEIL3 802版本编译通过,将所有的.C文件添加到工程中,并编译main.c
注意两点:1.器件选择c8051f120.
2.在target中将时钟设为96M.同时必须将Memory Model 改成large--XDATA.默认的是small.
因为本设计占用的资源是非常大的.
Program Size: data=81.3 xdata=6811 code=43056-2007 National Undergraduate Electronic Design Contest, A title of the audio signal analyzer full source code. Singlechip c8051f120, system clock multiplier to 96MHZ. main.c is a menu that contains the main function 5. FFT.C is fft transform, time-domain signal will be converted into frequency domain signals. flash.c are reading and writing flash memory chip procedure, the results of the analysis can be preserved, for calling. z7290.c weeks are Ligong 7290 driver keyboard chip. FFT_xgjis.c is transformed spectrum analysis and computing. Sine FFT_CodeTable.c is a table at a time when FFT calls. LCD320240.c are 320* 240 LCD drivers, LCD controllers are SED1335. all. h document provides the definition of Functions. Platform: |
