AWR2944: GPADC

Hello123

Part Number: AWR2944

In the structure of AWR2944, GPADC is in the RF/Analog subsystem, and main subsystem can use the GPADC for application usage, they are in different subsystem, how does MSS get the ADC value from RF Subsystem ?

Hi Jin,

There are two instances of ADC's in the SOC. One in the RF subsystem for Radar usage. And another GPADC is in MSS which can used directly like a normal ADC.

For usage of GPADC in MSS, drivers are available in MCU-PLUS SDK of AWR2944 on ti.com

by the way, whether MSS can use GPADC in RF subsystem ?

No, this is for Radar use. You should use the GPADC in the MSS.

But in TI document, it says it is a shared GPADC,and it has digital pin, am i correct ?

Hi,

This must be a typo in the safety manual. Can you please let me know the safety manual version you are referring to?

Meanwhile let me check on this and this typo will be fixed in next Safety manual.

In AWR2944, there are two GPADC, one in MSS another in BSS. If your aim is to measure an external analog signal from a pin, then you need to use the MSS GPADC.

Hi,

Chapter 7.32 is only referring to BSS GPADC. There is a separate Chapter GPADC for MSS, where MSS GPADC is explained.
