IWR6843AOP: SPI for Control and Data output

Vignesh Jeyaraman

Part Number: IWR6843AOP

Hello all,

I am working with IWR6843AoP SoC and have a few questions regarding the same.

1. I wanted to control the device with SPI (CLI Commands) and also get the output (point cloud and tracking) data via SPI. Is that possible ?

2. If yes, I wanted to know how much is the maximum data rate possible for data output via SPI.

Note : Since UART is slow, we are planning to shift to SPI. I am currently working on the 3D People Counting Demo. 

Thanks and Regards

Vignesh

    Hello Vignesh,

    It is possible to get the output via SPI using the SPI driver. The SPI driver has sample code within the mmWave SDK, and this driver can be used to replace the implemented UART driver. When you do this, you must reconfigure the pins by setting the SPI out pins for data. As for the maximum speed of SPI, we do not have an exact documented number but the practical range would be somewhere between 12 and 16MHz.
