AWR1443BOOST: AWR1443 and ESP32 SPI Communication

Tool/software:

Hello all,

I am working with the AWR1443BOOST board, and I'm wanting to pass the raw data from the AWR to an XIAO-ESP32C3 via SPI. I turned the S1 switch to the SPI position and have connected what I think are the correct SPI pins. Here are the connections that I have so far:

AWR (J6) ESP32

MCUCLK OUT (pin 5) SCK (pin D8)

SPI_CS (pin 6) D0

SPI_MOSI (pin 12) MOSI (pin D10)

SPI_MISO (pin 14) MISO (pin D9)

What do I need to do to get this SPI communication working on the AWR1443 end? (The AWR1443BOOST board is running the default demo program).

Hello,

Pin Connection:

MCU_CLKOUT to SCK -> Correct
SPI_CS to D0 -> You need to configur D0 to CS
SPI_MOSI to MOSI -> Correct
SPI_MISO to MISO -> Correct.

Please make sure to configue the CS on ESP32.

You will also need to do the following:

Configure SPI on AWR1443 using mmWave SDK
Configure the matching SPI settings on ESP32

It wouldnt hurt to use an Oscilloscope or a logic Analyzer to monitor and make sure the data is being transferred.

Hope this helps.

Thanks,
