Hello,

          I want to store the internal temperature data  into the array for timer interval 1 second .and i disable the timer interrupt after 5 second . but my question is that before disable the timer SPI interfacing is working correctly and after disable the timer SPI interfacing not working.What is the problem  with that?

    Hi,

    Depends on your code - if the SPI is accessed from timer interrupt, then disabling timer interrupt removes the SPI access - but at this stage this is only a supposition since we cannot see your code - please post it if you may...

    Hello Darshan,

    Can you please send the following information as well

    1. Which device it is TM4C123 or TM4C129?

    2. Can you share a code snippet as well?

    3. Another thing to check is SYSCTL.RCCGSSI register value when the timer is disabled?

    Regards

    Hello Darshan,

    But the original question still remains. Why should disabling the Timer Clock cause SPI stop working. After remounting the SDCARD, did you check that the timer is enabled or disabled?
