Hi Micheal,

For raw data capture other than I2C signal all the other signals are necessarily needed. We would recommend to have I2C also as it will be an interface to PMIC.

Hi,

Could you tell us the following signals are for what between the DCA1000 and AWR6843 ?

Hi Micheal,

SPI is used to send commands from studio to MSS application which calls mmWavelink APIs.
RS232 is used to download the firmware when using the mmWave studio.
I2C will be used for setting the PMIC configurations.
Pgood is an LED indication.
AR_RESET is to give the reset assertion from mmWave studio.

Thanks,
Kundan
