My LED's are not toggling when GPIO interrupt code is debugged.

There are no errors in my code. I have shorted the jumpers J2, J3 also.

Hi Udaya,

Do the LEDs turn on at all, like when you first plug in the board? You can confirm that your program enters the ISR properly?

I don't believe J2 and J3 effect any of the LEDs since they are for the I2C communication.

Best,
Kevin

Hi,

Please describe your issue better, because from your first post is not obvious what issue do you have.

Hi,
When the code GPIO interrupt is dumped into cc3200, the output LED i.e., led7 is not toggling. It just on's and constantly remaining in ON stage itself.

Hi,

Sorry I still not understand. How looks your code? Please share minimalistic code which show your issue. Do you have properly configured PINmux?

You have enabled interrupt from some GPIO and inside your ISR you control LED? Or what?
