The processing power of the STM32 is not sufficient to process the radar IF signal output from the AWR1243

thank you

what about awr1243 boost?

awr1243boost is the evaluation board for awr1243.

I am not clear what your question is

thank you

I need a radar sensore to measure distance and speed of vehicle, then i studied about TI products in this field.
I studied AWR1243Boost, and saw there are several out put on this board, uart,usb, spi and 20pin for tda3x.
i want connect stm32f103 to AWR1243Boost and use it to achive distance and speed, but i couldn't discover how to read data from AWR1243boost's ?(by spi or uart)

HI,

I suggest you use the AWR1642BOOST instead. This is a radar sensor with integrated signal processing engine.

www.ti.com/.../AWR1642BOOST

We have an example application to detect distance and speed using the AWR1642 boost:

www.ti.com/.../TIDEP-0092

This device has SPI interface that could be connected to STM32

Thank you
Cesar

Dear Cesar

I Saw that you told;but i didnt fine any information about SPI detail in it.

how i config my SPI,what is it mode ,and .....

for example when i read a data from SPI, what i read? or what is the SPI frame?

thank with best regards

I asked about SPI in AWR1642Boost, if that is not clear ,please tell to describe it , i want to know about SPI Satisfied and information in frame.

thanks

Hello Rafal,

First, you need to decide what is your use-case (distance, speed etc.) and based on that you can choose AWR1243 or AWR1642.

If you need to connect AWR1642 with STM32 (Host) then AWR1642 provides the miscllaneous interface (UART, SPI, CAN/CAN-FD) which you can use to communicate with Host.

UART- mmWave-SDK provides mmw demo which receives a command over UART and sends object data (from AWR1642) over another UART to Host.
SPI - Device can act as SPI slave/master in 3/4 pin. mmWave-SDK provides SPI unit test case along with SPI driver (<mmwave-SDK>\packages\ti\drivers\spi\test) which you can use as a reference to port any application to use SPI to communicate with Host.
CAN - AWR1642 can communicate with Host using CAN/CAN-FD, for more info please search this forum (e2e:mmwave_sensors) with CAN or CAN-FD, you will find many supporting answers.

And If you need to use AWR1243 device for your use-case and need to connect with STM32 then please use mmwave-DFP package which has reference code in form of mmwavelink_example application (<mmwave-DFP>\ti\example\mmwavelink_example). This application provides a reference to port SPI communication path on STM32 over which Host can configure AWR1243 with different configurations.

But to process raw ADC data, Host must have HSI capability(CSI-2 or LVDS) over which AWR1243 sends ADCBuffer raw data which Host needs to capture and process to obtain object result.

Regards,

Jitendra
