变量操作不起作用

大家好，我正在尝试读取和处理我的TCP/IP演示应用程序中的I2C数据。我使用了plib示例，它工作得很好（独立运行）。当我在演示应用程序中尝试做同样的操作时，它不工作。下面是我正在使用的代码：UINT8 i2cData[10]；UINT8 i2cbyte[10]；UINT16 up,low;UINT16 up1,low1,val；读取的数据存储在i2cbyte中。//变量操作up=i2cbyte[0];low=i2cbyte[1];up1=i2cbyte[0]<<6;low1=i2cbyte[1]>>2;val=up1|low1;示例值：i2cbyte[0]=0x0d和i2cbyte[1]=0xb9问题在于没有变量操作代码正在工作。我已经附加了调试器部分的屏幕截图。什么会引起这个问题？这可能是因为内存问题吗？而且，变量在某些情况下似乎具有相同的地址（在调试器中，也在PIC中看到）。应注意的是，该代码独立运行良好，只在演示应用程序中显示问题。

    Hi all,

I am trying to read and process i2c data in my tcp/ip demo app. I have used the plib example and it works well (stand alone).

When trying to do the same in my demo app, its not working. Below is the code that I am using :

    UINT8 i2cData[10];
    UINT8 i2cbyte[10];
    UINT16 up,low;
    UINT16 up1,low1,val;
The data read is stored in i2cbyte.
    // variable manipulation
    up = i2cbyte[0];
    low = i2cbyte[1];
    up1 = i2cbyte[0] << 6;
    low1 = i2cbyte[1] >> 2;
    val = up1 | low1;


Example value : i2cbyte[0] = 0x0d and i2cbyte[1] = 0xb9
The problem is that none of the variable manipulation code is working. I have attached a screen shot of the debugger section.

What could be causing this problem ? Could this be due to memory issue ? Also, the variables seems to have same address in certain case (seen in the debugger,also in the pic). Due note that this code works fine standalone and shows issue only in demo app.
