Hello Everyone,

I am having a hard time in reading gpadc values.

Could anyone help in this regard. Is there any reference code snippets available in the MMWAVE SDK?

I am not getting it over internet.

Thanks in advance.

Hi,

Do you need to read the GPADC information while chirping OR while in standalone mode? Please confirm.

Regards,

Hello Sudharsham,

Hi, Sudharshan

Well in my case I followed the Z:\ti\mmwave_sdk_03_05_00_04\packages\ti\control\mmwavelink but the MmwaveLink_asyncEventHandler callback is not getting hit.

some snippets

Mailbox_init(MAILBOX_TYPE_MSS)

MmwaveLink_initLink (RL_AR_DEVICETYPE_68XX, RL_PLATFORM_MSS )

MmwaveLink_setGpAdcConfig()

Is there any other resources available/ application notes? It would be of great help.

Thanks in advance.

API sequence all is as follows

Mailbox_init(MAILBOX_TYPE_MSS)

MmwaveLink_initLink (RL_AR_DEVICETYPE_68XX, RL_PLATFORM_MSS )

MmwaveLink_setRfDevCfg(0x0)

MmwaveLink_setGpAdcConfig()

Hi,

The above method would work during active chirping to report the GPADC data. For single shot GPADC reads there are additional changes needed. Below is a sample code to read GPADC data when chirping is not active.
