uclinux下的一个窗口显示程序

可以通过QPBOC检测 里面有emv内核源码 和qpboc的一些文档的数据结构定义和代码的介绍 里面有大量的注释 很好的代码。

用ＰＩＣ１６Ｆ６９０单片机实现终端采样、检测和与ＰＣ通讯-PIC16F690 Microcontroller with terminal sampling, detection and communication with the PC

目前国内有关数字信号处理的教材在讲解快速傅里叶变换（FFT）时，都是以复数FFT为重点，实数FFT算法都是一笔带过，书中给出的具体实现程序多为BASIC或FORTRAN程序并且多数不能真正运行。鉴于目前在许多嵌入式系统中要用到FFT运算，如以DSP为核心的交流采样系统、频谱分析、相关分析等。本人结合自己的实际开发经验，研究了实数的FFT算法并给出具体的C语言函数，读者可以直接应用于自己的系统中。--I implemented FFT algorithm in real number and provides a C function. Users could use it directly in their systems.

Part IV In part II we discussed the conversion of binary numbers into decimal digits. It is sometimes useful to build circuits that use this method of representing decimal numbers, in which each decimal digit is represented using four bits. This scheme is known as the binary coded decimal (BCD) representation. As an example, the decimal value 59 is encoded in BCD form as 0101 1001. You are to design a circuit that adds two BCD digits. The inputs to the circuit are BCD numbers A and B, plus a carry-in, cin. The output should be a two-digit BCD sum S1S0. Note that the largest sum that needs to be handled by this circuit is S
