在睡眠模式下使用ADC的示例代码？

我有一个使用PIC18F66K22的设计，它在非睡眠模式下使用ADC工作“OK”，但是结果似乎随固定输入变化约10%。我做转换8次，取平均值，但仍然看到很多变化。我想尝试在睡眠模式下运行ADC，看看这是否会改善结果。我已经尝试了一些方法，但是PIC似乎挂起了。有人能指点一下在睡眠模式下使用ADC的一些示例代码吗？我已经尝试过搜索，并且找到了一些使用HITECH内置例程的例子，但是我无法弄清楚例程是什么样子，我正在使用XC8编译器。谢谢，Pete。

    I have a design using a PIC18F66K22 that is working "OK" using the ADC in non-sleep mode, however the results seem to vary with a fixed input by about 10%.  I am doing the conversion 8 times and taking the average, but still see a lot of variation.  I wanted to try running the ADC in sleep mode to see if this would improve the results.   I have tried a few ways to do this but the PIC seems to hang.

Can anyone point me to some sample code that uses the ADC in sleep mode?  I have tried searching around and have found some examples using the HITECH built-in routines, but I was not able to figure out what the routines looked like and I am using the XC8 compiler.

Thanks,

Pete
