My settings are as follows:

1. IWR6843AOP

2. MMWAVEICBOOST

3. 3D_people_count_6843_mss/dss

I want to send SPI data as belows

uint8_t testbuf[] = {0xFE, 0xFE, 0x0C, 0x01, 0x04, 0x30, 0x31, 0x32, 0x33, 0xEF, 0xEF, 0xF6};

But I failed it.

I have updated code simply. It code, I have attached it below. Please kindly guide me.

SPI setting is started after "SPI_Params_init();"

my tried SPI write is started in MmwDemo_spiTxTask.

Hello,

What versions are you using for both the Toolbox and the mmWave SDK? Also if you are not already aware, the SPI test code can be found at <SDK_INSTALL>/packages/ti/drivers/spi/test/xwr68xx. This may be helpful to reference.

Best Regards,

Josh

Hi,

Did it help to reference the SPI driver test code? Is there any specific question you have in regards to the SPI driver's usage?

Best Regards,

Josh
