当传感器上的负载发生变化时，ADC显示没有值的变化

我修改了AdCl微分器前置放大器项目，用PSoC 4 BLE先锋套件和附图中所示的加载单元工作。它最初工作，报告MVoT值在大约70（IIrc）和1024之间，这是最大值。
然后我想做什么用redexcite和yellowexcite引脚反向ADC读数之间的激励电压的极性幻想，要减去反向极性测量从正常极性测量作为一种手段来有效的解决双。在没有得到那个工作，但是，我回到我之前保存在这个变更项目。
问题是，现在第一个项目也不起作用。ADC值无变化时，传感器上的负载的变化。检查两个数字多用表，我可以看到，差分电压进入销bluesense和whitesense仍然变化始终与负载一如既往。测量out_1和out_2，之间的电压，但是，这应该是完全一样的是美联储的ADC，只读取0 V，偶尔漂流到0.1 mV。由于固件只计算到1 mV值，这mvolts总是等于previousvalue也被写入UART是有意义的。
我炸了我的眼镜吗？幸运的是，我有一个包或两个在路上，但我想知道如果运算放大器，实际上，油炸，或是我有一些其他的错误在我的项目，我失踪。我可以分享其余的项目太多，如果能帮助。
谢谢，Don。

  I modified the ADC_Differential_Preamplifer project to work with a PSoC 4 BLE Pioneer Kit and with a load cell as shown in the attached schematic. It worked initially, reporting mVolt values between about 70 (IIRC) and 1024, which is the maximum.
    I then tried to do something fancy by using the redExcite and yellowExcite pins to reverse the polarity of the excitation voltage between ADC readings, intending to subtract the reversed-polarity measurement from the normal-polarity measurement as a means to effectively double the resolution. After failing to get that to work, however, I returned to the project I saved before trying this change.
    The problem is, now the first project doesn't work either. The ADC is showing no change of values when the load on the sensor changes. Checking with two DMMs, I can see that the differential voltage going into pins blueSense and whiteSense still varies consistently versus load as it always has. Measuring the voltage between Out_1 and Out_2, however, which should be exactly the same as is being fed to the ADC, reads only 0 V, occasionally drifting to -0.1 mV. Since the firmware only calculates down to values of 1 mV, it makes sense that mVolts is always equal to previousValue so that nothing is being written to the UART.
    Did I fry my opamps? Fortunately, I have another kit or two on their way, but I would like to know if the opamps are, in fact, fried, or whether I have some other error in my project that I am missing. I can share the rest of the project too, if that will help.
    Thanks, Don.
