TMDS273EVM: Is it possible to combine AWR2243BOOST + TMDS273EVM+DCA1000EVM for real-time point cloud visualization and ADC data capture simultaneously?

Can AWR2243BOOST + TMDS273EVM alone perform both real-time point cloud visualization and raw ADC data capture at the same time?

[RR] It depends on what performance you need. The AWR2243BOOST can send ADC samples over CSI2 to the TMDS273EVM, then the AM273x device can process those frames however you'd like within its processing and memory limitations and send raw ADC data, or processed data over any of the available peripherals (UART, MCAN, 100Mbit Ethernet).

If the point cloud density is sufficiently limited to fit within the data rate limits of the available peripherals, then YES, the TMDS273EVM can stream pointcloud data and raw ADC data.

The AWRx maximum ADC output data rate is limited CSI2 TX 900Mbps/lane or 3.6Gbit/s total and is duty cycle limited by the chirp duty cycle and requested frame rate. The AM273x can process data at speeds sufficient to keep up with the AWRx sensor data rate. But the AM273x cannot stream out raw ADC data samples, or highly unprocessed, higher density point-cloud data.

Is it possible to cascade TMDS273EVM and DCA1000EVM together with an AWR224BOOST board to achieve both functionalities?

[RR] No. The AM273x does not support the DCA1000EVM in any way. They are totally separate platforms.

If cascading is not supported, can I use two AWR2243BOOST boards—one with DCA1000EVM for ADC capture and the other with TMDS273EVM for point cloud visualization?

[RR] I don't see what would limit you being able to set up an AWR2243BOOST + DCA1000EVM and another, separate AWR2243BOOST + TMDS273EVM. Maybe I am not understanding your question though. The DCA1000EVM is intended for data capture and offline processing. The TMDS273EVM is intended to help develop realtime data processing.

Is there any official Quick Start Guide for using AWR2243BOOST + TMDS273EVM? If not, could you please give a brief instruction on how I should connect them?

[RR] The best examples are located in the following SDK documents.
AM273x SDK: www.ti.com/.../MCU-PLUS-SDK-AM273X
AWRx sensor SDK: www.ti.com/.../MMWAVE-SDK
AM273x + AWRx sensor SDK: www.ti.com/.../MMWAVE-MCUPLUS-SDK

Regarding the HQCD-030-12.00-TEU-SEU-1 cable used for these boards, are there any pin-order or polarity considerations to avoid damaging the hardware?

[RR] Yes. The Satec HQCD cables, and the mating QSH connectors on the boards are both keyed such that you cannot connect cables to the connectors in an incorrect orientation.

Please let me know if you have any additional questions on these topics. 

Thank you,
