MCC172 examples C data_logger

[AndyCH]

我可以執行示例 C“記錄器”。

但我看不到 Y 軸單位。

我通過信號發生器輸出“10Hz”“正弦波”。

請告訴我我可能做錯了什麼。

I changed the board from 64bit to 32bit to solve this problem.

Hello,

I could not duplicate the x-axis scale issue that you reported so it could be regional caused by the local language being mishandled.

Best regard,

HI JRys

when I check the local language. Everything is ok
So I print "logger.c line179 freq_val value" on the console.

I can see the value is right.

But the X-axis still display "0".

Maybe there is a problem with the displayed part.

Can you help me to confirm this part?

Thank you

Hi Andy,

I was able to duplicate your issue using 64-bit Raspbian. 

MCC did not fully test the DAQHAT support & examples using 64-bit Raspbian and for this reason we continue to recommend that the 32-bit OS be used. I will report your findings to engineering and hopefully a future release will address the issue.

Thank you for letting me know.

Best regards,
John

Hi Andy,

Engineering was able to fix the issue rather quickly thanks to your help. Apparently, it was an incorrectly formatted string in the logger.c file that caused the x-axis scale to be wrong. The fix was tested on both the 32 and 64-bit Raspbian.
