最新版的佳能单反相机开发包，国内下载不到哦 Canon Digital EOS SDK ED-SDK v2.11 支持以下相机： EOS-1D Mark III EOS 40D EOS-1Ds Mark III EOS DIGITAL REBEL Xsi/450D/ Kiss X2 EOS DIGITAL REBEL XS/ 1000D/ KISS F EOS 50D EOS 5D Mark II EOS Kiss X3/EOS REBEL T1i /EOS 500D EOS 7D EOS-1D Mark IV EOS Kiss X4/EOS REBEL T2i /EOS 550D EOS 60D EOS Kiss X5/EOS REBEL T3i /EOS 600D EOS Kiss X50/EOS REBEL T3 /EOS 1100D EOS-1D X EOS 5D MarkIII EOS 60Da EOS 650D (The latest version of Canon SLR camera development kits, domestic not download Oh Canon Digital EOS SDK ED-SDK v2.11 supports the following cameras: EOS-1D Mark III EOS 40D EOS-1Ds Mark III EOS DIGITAL REBEL Xsi/450D/Kiss X2 EOS DIGITAL REBEL XS/1000D/KISS F EOS 50D EOS 5D Mark II EOS Kiss X3/EOS REBEL T1i/EOS 500D EOS 7D EOS-1D Mark IV EOS Kiss X4/EOS REBEL T2i/EOS 550D EOS 60D EOS Kiss X5/EOS REBEL T3i/EOS 600D EOS Kiss X50/EOS REBEL T3/EOS 1100D EOS-1D X EOS 5D MarkIII EOS 60Da EOS 650D)

宽频放大器,有以下功能: 预置增益,增益加/减,显示输出电压有效值,自动增益 显示有效值. 增益输入及加减 自动增益没有实现(Wideband amplifier has the following functions: Preset gain, gain plus/minus, the display output voltage RMS, automatic gain display rms. AGC gain input and subtraction is not implemented)

此程序可实现长度为8位，周期为255的m序列，此序列可当做伪随机信号发生器，模拟信道噪声。(This procedure can achieve the length of 8 bits, the m sequence of 255 cycles, the sequence can be used as a pseudorandom signal generator, analog channel noise.)

msp430实现12864的菜单显示功能(msp430 realization of the menu display 12864)

带参数存储的整点报时音乐电脑时钟，算是一个比较适合初学者一个小系统。有一定的参考价值。(With parameters stored in the computer clock chime music, be a more suitable for beginners a small system. Have a certain reference value.)

说明：  看电子电路时序图如何看，这是个好方面，可以看看(Electronic circuit timing diagram to see how the look, this is a good side, you can see)
