MSP430FR5994: transform_ex1_fft_fixed_q15

Part Number: MSP430FR5994

If I use the data collected by the ADC module that comes with the MSP430FR5994, how should I convert the data format to the array input in the example transform_ex1_fft_fixed_q15 for direct use.

    Hi Yale,

    The input array is just a collection of Q15 input values. 

    You would need to add your ADC capture to the example and adjust it so rather than using the signal created in initSignal you load the input array with your ADC values (transformed to q15 format), and then call MAP_msp_fft_fixed_q15 to process them when the collection of samples you want to transform is ready. 

    Best Regards,
