如何在PSoC3上做暗探测器

嗨，我又创造了一捆。我仍然有相同的问题与中断不工作，也在添加一个while循环。

          Hi again I created a bundle. I do still have the same problem with the interrupt not working, also after adding a while-loop.

我建议你在TIA的输出端加一个模拟管脚，测量电压。TIA正在倒转，我不太确定极性是否正确。

  I would suggest you to add an analog pin to the output of the TIA and measure the voltage. The TIA is inverting, I'm not quite sure if the polarity is right.

TIA的转换g是反馈http://en.wikipedia.org/wiki/transimpedance_amplifier R.
你要衡量abvsolute光水平，或者只是简单地打开/关闭
基于一个简单的传感器，如反向偏置二极管？如果前者校准
传感器可从Avago，Rohm，VISHY等。如果后者只是一个比较器
TIA一般来说绰绰有余。事实上，你可以通过使用简单的方法来消除短暂性脑缺血发作。
一种基于R的光电池，如镉型细胞控制输入电平在分频器
比较器。在这个配置中设置比较器与歇斯底里。

问候，Dana。
代表性的例子（照片可能是镉或二极管或光电晶体管，显示W / O回）—



     以下为原文
  The conversion G of the TIA is its fdbk R.                 http://en.wikipedia.org/wiki/Transimpedance_amplifier
     
    Are you trying to measure abvsolute light level, or just simply turn something on/off
    based on a simple sensor like a reverse biased diode ? If the former calibrated
    sensors are available from Avago, Rohm, Vishay, and others. If latter just a comparator
    and TIA is generally more than enough. In fact you could eliminate TIA easily by using
    a R based photocell, like a cadmium type cell controling input level in a divider to
    comparator. Set the comparator up with hysterisis in this configuration.

我想在PSoC3上实现整个事情。它应该相当精确，但基本上它的目的是打开/关闭灯。
ADC采样如何？



     以下为原文
  I want to implement the whole thing on the PSoC3.  It should be pretty precise, but basically the purpose it turn light on/off.       

    What about sampling with an ADC?        

如果精确的话，你需要一个已知的光水平，它会在下面移动
可以使用-
1）假设，使用未校准的廉价传感器，如二极管或CDS光电池或
光电晶体管。这意味着你必须校准你想要的产品的行程水平。
装运。在生产测试过程中进行简单测试。
2）感知你所需要的只是比较器。但要做CAL两种方法——
使用A/D和TIA开发A/D信号，在生产测试过程中按A按钮。
并使用A/D读取校准光源，并将该值存储在EEPROM中。
然后用A/D读数将当前读数与CAL读数进行比较。
测定。如果你用简单的R分频器使用CD，你可能不需要TIA。
输入到A/D中。
使用传感器+比较器+VDAC8。VDAC8用于向比较器提供偏移量。
在生产测试过程中，校准光源将VDAC8值转换为行程，
将它存储在EE中，并且每次产品通电时，它读取EE值和
并将此写入VDAC8一次，以抵消比较器跳闸点。
问候，Dana。



     以下为原文
  If by precise is you need a known light level at which it trips, the following
    could be used -
     
    1) Assumptions, you use an uncalibrated cheap sensor, like diode or CDS photocell or
    photo transistor. This means you have to calibrate to the trip level you want the product
    to ship. A simple test during production test.
    2) To sense all you need is a Comparator. But to do cal two approaches -
           a. Use A/D and TIA to develop signal for A/D. Press a button during production test
               and using A/D read a calibrated light source, and store that value in EEPROM.
               Then future readings with A/D will compare current reading to cal reading to make
                determination. You might not need TIA if you use CDS in a simple R divider to
                input into A/D.
           b. Use sensor + comparator + VDAC8. VDAC8 used to provide offset to comparator.
               During production test with calibrated light source slew VDAC8 value until it trips,
               store that in EE, and everytime product is powered on it reads the EE value and
               and writes this to VDAC8 once to offset the comparator trip point.

这可能也是有用的。
