AWR1642: Start and sipmle question

Part Number: AWR1642

Hello. I am watching on different documnetation about Radar sensor. I don't have dev board yet , but i am thinking about this. I have few questuion about this platform.
1) Does TI sdk support other peryperial such as timer, ROTS,SPI, etc aviable for user app?
2) Does TI provide some api for handle user resources ? Where i can found this ?
3) How many RAM can be used for cutomer app, when some examples is runing?
4) If i good understand , this sensor use only SQI Flash? for customer app also?
5) What is minium hardware for debug and run example app (modifed by user)

1) Yes, please dowload the SDK. You will see the list of supported peripherals

2)What do you mean by user resources?

3) It will depend on examples running. What type of app do you plan to run?

4) Yes QSPI flash

5) Min hardware is EVM. If you plan to capture raw data you would need also a DCA1000 EVM

Thank you
Cesar

Thanks for answer.
1) I ask because i am absolute new in TI mcu solution, some expression fro TS for me are absolute new. Download and SDK and recognise spend a lot of time .... I don't know at the moment that it is good solution for me, i make sure only.
2) user resources it mean that sensor give some RAM memory for analyse data, timer for time mesurments, interrupts, etc.
Some examples give an output data for analyse by matlab.
Can i analyse myself, by user function inside MCU sensor?.
for example I need use only GPIO 1/0 , when tracked car are present in specified area, and moved out in specified speed. For anlysye this data i need extra host MCU, or can I analyse inside sensor ?.
If inside sensor i need resources: RAM, CPU, TIMER, interrupts, etc.
I need to know, what i can do inside sensor, and what no....
I need know about cpu ussage/RAM in percent, for examples supported by TI
3) generally inteligent sensor for traffic mesurmnets on road.
speed, lenght, road line occupancy, traffic degrre saturation,
selective occupancy on specified area.
As output device will produce very simpe data, I/O, an serial simple data. No radar image are neccesery for post processing by other device

Hi,

The TI AWR1642 mmwave sensor is a programmable sensor. It includes ARM and DSP programmables cores.

All the processing is performed inside the sensor. And processing results are sent to a host through UART, SPI or CAN/CANFD.

There are a large variety of demo applications already available for free on the TI Resource Explorer:

dev.ti.com/.../

Please see Industrial and Automotive Toolbox.

You don't need to run the code, just look at the User Guide to get an idea of the applications

thank you
Cesar
