TDA4VM: There are no demos of input capture of TDA4VM. I don't know how to use it.

Lu Zhiang

Part Number: TDA4VM

The input signal for Ultrasonic radar is PWM,but there is no demo about Ultrasonic radar in SDK, could you do a demo for us?

Our input signals of radar is like below:

We can provide the HW environment and the radar sensor, if you can provide one demo for these signal analysis it will be very nice!

You can look the randar spec at our office if you need.

Can you take a look at this thread which lists PWM example ?

dear expers:

we also need the ICU (input capture module eg, timer capture) function demo code to developing the Ultrasonic drive!

Hi, BinBin,Lu:

I have developed two patches to demonstrate the capture of GP timers.

patch for pdk folder:

patch for vision apps folder:

Please take a look and we can discuss on how to test on your hardware.

CSL also has an example on capturing using the onboard ECAP module. The example is not in SDK yet so to get it

Clone the release branch of with the command

git clone --single-branch --branch release

Go to examples/ecap folder.

This example is for AM64 device but you can adapt it for TDA4 using the TRM.

Hi, Lu:

Here is an example of how to route Timer19 IRQ to MCU_R5f0_0.
