IWRL6432AOPEVM: Where do i find GPIO pins for SPI communication on the EVM board

do i need to use DCA1000 connector to communicate with IWRL SPI pins?

My question is how do i tap SPI and verify SPI data(I don't have DCA1000 connector). I want to send this SPI data to another Microcontroller.

I am working with the IWRL6432AOP EVM.

My goal is to capture the radar output over SPI and forward the stream to an external microcontroller.

I understand that the DCA1000 capture board is typically used for LVDS/ADC data, but I do not have the DCA1000 connector available in my setup.

I enabled SPI streaming in the firmware and can see data on the UART port.
However, I would like to physically tap the SPI lines and read them using another MCU.

The problem is that I cannot clearly identify in the schematic or board documentation:

1. Which pins carry the SPI stream from the device

2. Whether these pins are routed to headers or test points

3. If level shifting or buffering is present

4. Whether additional configuration is required in firmware to mirror data to SPI

Could you please guide me on where these SPI signals are accessible on the EVM, or whether hardware modification is required?

Hello,

You can use the FTDI chip and thus the USB interface embedded on the IWRL6432AOP. Unless you are saying you HAVE to use the pins built into the EVM?

Here is a SPI Data Capture guide where you stream data live.

Hello Lydia,

Thank you for the user guide — it was very helpful.

I have a follow-up question regarding SPI communication on the IWRL6432AOPEVM. My goal is to send occupancy/presence detection output to an external MCU connected via the J2 SPI Header pins.

Specifically, I'd like to know:
1. Is a custom parser needed to interpret the SPI data on the receiving MCU side?
2. Do I need to modify the existing example project in CCS to transmit only the presence/occupancy information over SPI, rather than full ADC data?

Any guidance or pointers to relevant example code would be greatly appreciated.

Best Regards,
