Can a ticker call a function at a constantly varying time?

Hi

You probably need to detach the ticker before selecting a new sample rate:

void sample_rate(){
    ADC_sampling_rate=((float)t_period/1000000)/32;   //divides period by 32 to calculate sampling rate (in sec) for 32 samples per period
    ADC_set.detach();
    ADC_set.attach(&ADC,ADC_sampling_rate);
}

Are you sure that the 128 samples have not yet been collected before you attempt to select a new rate. In that case it would never get selected because the while loop has finished.

Hi Wim

I have tried changing the size of the array and the length of time the sample function is being called which updates my ticker with a new time value but I cant seem to figure it out, have you any ideas as to why this is not working??

Thanks

I have used a ticker with a varying time with no problems, what you may need to look at is the rate value, to be sure it can be achieved.
