ADC值不遵循输入？

我的计划有两热敏电阻以及其他一些需要监测的模拟值。所有相关的引脚是高阻抗模拟输入具有高初始驱动（尝试），进入adc_sar_seq_p4_v2_50.now，我以为这会是一个扣篮。我跟着一些例子大部分都同意了，所以我把我的项目看起来像那些。
但在开始转换，等待完成，我没有看到任何有意义的变化的数据。我可以测量电压在热敏电阻进入董事会，这确实是改变。
我想我或许需要引脚外部终端，但这并不重要，和其他的例子通常不使用它。我不使用硬件触发文档adc_start()表示它的替代品（adc_fw_trigger），和adc_isendconversion()看起来很快乐。
我上传的档案里有没有引脚的外部端子，虽然似乎没有关系。
我左右为难，谁能告诉我，我有点搞砸了什么？
谢谢，约翰

  My project has a couple of thermistors along with a few other analog values that need monitoring. All associated pins are high-Z Analog inputs with high initial drive (tried both), fed into a ADC_SAR_SEQ_P4_v2_50.
Now, I thought this would be a slam-dunk. I followed a number of examples - most of them agreed, so I made my project look like those.

But after starting a conversion and waiting for completion, I don't see any meaningful change in the data. I can measure voltage where the thermister comes into the board, and it is indeed changing.

I thought perhaps I needed external terminal for the pins, but it didn't seem to matter, and other examples don't typically use it. I'm not using a hardware trigger - documentation for ADC_Start() indicates it's a substitute ( ADC_FW_TRIGGER), and ADC_IsEndConversion() seems entirely happy.

I've uploaded an archive of the case where there are no external terminals for the pins, though that doesn't seem to matter.

I am in a quandary - can anyone tell me what bit I have messed up?
Thanks,
John
