[MacOS develop] AD0804 DL : 0: 关于adc0804的基本应用，ADC0804是用CMOS集成工艺制成的逐次比较型摸数转换芯片。分辨率8位，转换时间100μs，输入电压范围为0~5V，增加某些外部电路后，输入模拟电压可为 5V。该芯片内有输出数据锁存器，当与计算机连接时，转换电路的输出可以直接连接在CPU数据总线-About adc804 basic applicationsADC0804 is made with CMOS integrated process of successive digital conversion chip comparative type touch. Resolution 8 bits, conversion time 100 muon s, input voltage range is 0 ~ 5V, adding some external circuits, input analog voltage may be 5V. The chip has output data latches, when with the computer connection, converting circuit output can be directly connected to the CPU data bus

[MacOS develop] DDS DL : 0: 第一，DDS模块是一个比较常用的用数字方式实现模拟信号的方法，以前一直只用了频率控制，这一次还通过深入理解用上了相位控制，从这个角度来讲，可以用FPGA小菜一碟的实现频率和相位可控的多通道SPWM波，然后再去外加上RC滤波电路和运放电路就可以实现可控正弦波。第二，这里的DDS模块还有产生一个可逆计数器的计数使能时钟和方向控制时钟，需要具体说说的是，如果你输出的正弦值是8位的，那么你的计数器的计数范围是在0---255---0，如果你输出的正弦值是9位的，那么你的计数器的计数范围是在0---511---0。还有，每此计数变化后（一个“数字”三角波产生），DDS中只输出一个正弦值，进行比较。-First, the DDS module is a more commonly used in digital way to realize analog signal, the method of used in frequency control, this time also by deep understanding of using phase control, from this perspective, you can use the FPGA implementation of a piece of cake of frequency and phase controlled multichannel SPWM wave, and then to plus the RC filter circuit and the op-amp circuit can realize controllable sine wave. Second, the DDS module and create a reversible counter count can make the clock and direction control clock, need specific about is that if you output sine value is 8 bits, so is the scope of your counter counts in 0-255-0, if your output sine value is nine, so is the scope of your counter counts in 0-511-0. Also, every change after the count (a "number" triangle wave), only in the DDS output a sine value, the comparison
