i need to read 4000 sequential adc data and need an interrupt that every time a 100kHZ pwm goes from low to high or high to low. i am using f401re and i think it is capable..
appreciate any help


  • Hello @orhanerdem ;

    the frequency requirements should be no problem for the f401re; however I am not positive I have completely understood  your needs. Do you need one sample every interrupt? or you need to generate a pwm while reading the adc?

  • sorry for my English.
    i need one sample every interrupt and it should occur every time the pwm signal(100khz) goes from low to high 

    in mbed i manage to do that on time 

    for (i=0;i<3648;i++){

    void record()
      pixelValue[i]= imageIn.read_u16();
