LAUNCHXL-F28379D: Inter-Process Communication (IPC driver API, adc interrupt and ipc interrupt)

Tool/software:

Hello there,

I am trying to send a data (32-bit value) from core1 to core 2.

I am using ADC interrupt on core 1 in which I am calling IPCLtoRDataWrite() function to send adc_result to core 2 where I have ipc0_isr() which is not triggering. Could you look at the code below to see what I am doing wrong?

This is core 2 main()

Thanks,

Hi,

What is 'NO_FLAG', if you want to trigger IPC0 ISR on CPU2, you need to set IPC FLAG 0 high going from CPU1 to CPU2. This would trigger IPC0 ISR if the interrupt is setup correctly.

To see how to set everything up correctly, I recommend that you start by using one of our IPC examples.

Best Regards,

Ben Collier

Hello Benjamin,

This is from one of your examples (see below) basically I was following this and if you see for the same function they also don't have flag set.

thanks,

Sumit,

Sorry, I was not familiar with this example. Is there a reason that you are not using the driverlib examples?

Best Regards,

In C2000WARE, look inside the driverlib folder. Then select your device, and select examples.
