    problem using FFT code from Microchip

    fft for microchip I am getting the FFT souce code from microchip website for DSPIC30F6014A. I wonder anyone use before . However, I am using the DSPIC30f3010. When I run it with the origal pic setting i could view the result from watch window . When I change the setting to my own PIC , it...

    Storage of ADC result in dsPIC

    dspic adc I am doing ADC on a current signal to perform FFT using DSPIC30F3010. I have written the ADC coding with help from the data sheet . The result should be store in ADCBUF0 . However , when I try to view the result using MPLAB IDE under IDC2 debugger mode , the value of the register...

    How to FFT signal practically (urgent)

    I am a bit confused and only study FFT in theory . I never did it in practical before . If I have a 50Hz sine wave measured as current waveform , FFT the signal I have read that I need to sample it at at least 2*50Hz ... which is a minimum of 100 Hz . How do I do it practically as in sampling...

    Need help with input capture using DSPIC

    input capture dspic thanks again ... i manage to get already =) i did it all in integer ... cause the accuracy level i nneed its not that high ...so i scale up my reading ... however my debugger still show resreicted memory ... now i use MPLAB SIM ... and watch it through watch window...

    Need help with input capture using DSPIC

    dspic input capture I am a new user using DSPIC30F3010. I am trying to use the input capture module to capture the period of squarewave using the MPLAB IDE to do my programming. I am using the ICD2 to view the result of my register which is IC7BUF. I am not getting any changes in the buffer ...
