TMS320F28069M: Hardware interrupt based ADC is not working

ASHWINEE JADHAO
Expert 1010 points

Part Number: TMS320F28069M

Hello,

As I have posted same query on MATLAB forum too but no reply yet I am asking this query here.

I am using Hardware interrupt based ADC, using TMS320F28069M LAUNCHPAD in SIMULINK. After I get hardware input then and then only LED will glow.

But right now I execute code properly and without providing  any external input to ADC on hardware my LED turns off!!!!

Please tell me what I am missing in the program.

Thanks 

with regards,

Ashwinee

    Ashwinee,

    The MATLAB forum is the right place to post questions when developing with Simulink.

    I suspect that you have not received a reply because there is so little actionable information provided in your problem description. I recommend that you update your MATLAB forum post with additional details such as:

    • Which LED are you referencing? There are multiple on the board.
    • What is your expected behavior for the LED?
    • Explain why you believe the LED should behave in the manner that you expect.
    • How is the observed LED behavior different from your expectations?
    • Based on your knowledge of the program, do you have any hypotheses that might explain the observed behavior?
    • What debug steps have you taken to identify the underlying problem?
    • What are the results of the debug steps?
