PGA970: Can not enter the ADC interrupt handler

FRANK1

Part Number: PGA970

Hi Team,

A student customer can not post in E2E, so I help him post this technical issue.

Could you please review the query?

question:
theme:the firmware I downloaded can not enter the ADC interrupt handler.
contents:

Hi, I am new to pga970 and I have downloaded the full data sheet and the firmware.
I used xds200 and loaded the firmware into the pga970 successfully. But I noticed that
the variable adccount1 didn't change which means the program didn't enter into the
adchandler. Could you help me with that? I also had some pictures.

Thank you for your time.

Thanks.

Regards,

Hi Frank,

Our firmware development support for the PGA970 on E2E is very limited. Please refer your customer to this post for more information: https://e2e.ti.com/support/sensors-group/sensors/f/sensors-forum/802433/what-is-the-e2e-support-model-for-the-pga900-and-pga970

The latest technical documentation is available through the same My Secure Resources page where the PGA970 datasheet, GUI, and generic firmware are posted.

As a note, the generic example firmware is provided as a starting point, but is not a complete and fully functioning application example. The file structure and shell functions are provided as a baseline, but will need to be expanded on by the user.

Regards,

Scott
