Part Number: AWR6843AOP

Hi,

I want to design a new hardware, which can support input power monitoring. Such as input power high/low.

Does AWR6843AOP have ADC function that can monitoring input power?

Thanks,

Hi,

Are you looking for power rail monitoring? Please let us know. If this is for power rail monitoring like VBAT we can use GPDAC for the same.

Hi Sudharshan,

Thanks for your reply.

I want to monitor the input supply voltage level. Do you have sample code using GPADC?

Thanks,

Yunlong

Hi,

Do you need to monitor the voltage while the device is chirping OR when it is not active. If voltage monitoring is done while the device is chirping then periodic reports can be enabled that will send teh ADC information. Please let me know the details.

Hi,

Thanks for the response! Please refer to rlSetGpAdcConfig() in the SDK \ti\mmwave_sdk_03_05_00_04\packages\ti\control\mmwavelink\src\rl_sensor.c.

This has the configuration setting that needs to be done to enable GPADC reads.
