I have put break points on TIM2_IRQHandler and I am never seeing this code called.

I have set the the following as per the docs:

void initUserDataProcessingEngine()
{
InitUserAlgorithm(); // default implementation located in file user_algorithm.c
platformEnableGpsPps(TRUE); // Init PPS sync engine
}

What am I doing wrong?

Could you tell me more details about what you want to do? So, I can get a firmware engineer to help you.

I am trying to work out if the pps code actually works and what it is doing, I have the IMU connected to a Ublox zed-f9p with the pps connect to pin 2 . I now can see that the interrupt is being serviced, but I can't work out in the code as bits are commented out if the timestamp is being adjusted accordingly.

Looking at in DataAcquisitionSupport.c and ONE_PPS_EXTI_IRQHandler.

Why is ppsDetected commented out?

void ONE_PPS_EXTI_IRQHandler(void)
{
OSEnterISR();

if(platformIsGpsPPSUsed()){

// ppsDetected = 1;
}

EXTI->PR = ONE_PPS_EXTI_LINE;  ///< Clear the interrupt bit

OSExitISR();

}

I can see how ppsDetected is set in Timer5, but as far as I can tell timer5 isn't triggered by the pps input on pin 2.

Timer0 gets trigger by the input on pin 2.

My question as I can't figure it out, is how is the timestamp being synchronised by the pps input?

Many thanks,

Simon

Bump

Are you guys still working?

Please can you confirm that the time stamp is being synchronised by the external PPS signal as I cannot see how it is?

Please correct me if I am wrong?
