problem with xadc header (conversion AD)

Hello,

I write because I made a test conversion of analog input voltage of Zedboard, I managed to read a voltage at the beginning, but as the pins (xadc header) are close, I think there had some contact between pins.

Before I read the value of the A / D conversion using the SDK using (xsysmon_polled_printf_example.c) but now I have no answer function:

while ((XSysMon_GetStatus (SysMonInstPtr) & XSM_SR_EOS_MASK)! =
XSM_SR_EOS_MASK);

The XSysMon_GetStatus (SysMonInstPtr) function is always the value 0x80.

I do not know how to solve this problem.

fpgainitiat,

Is it possible that you migrated from a previous BSP to a current one and the driver files/functions are the same, or are you mixing examples with examples of different tool versions. There is a nice reference that I think you might find useful.

All programmable planet did a great write-up that used the XADC. Part-7 touches on interfacing in SDK:

The author included the project file here:

Take a look at those and let me know if that answers your question.

Thanks,

-TD

Hello,
Thank you for your answer.
I created another project with a new BSP, but it does not work, this still blocks the function that receives the data conversion (It means the converter process of converting endless).
Is that you have another idea?
Thank you.
