Modification Project of Pavel demin (Frequency counter-4) into realtime FIR

[amin]

Hello all,
I want to make a realtime FIR filter from Pavel demin's project (frequency counter-4).

Frequency_counter_pavel.JPG

I have tried to make a modification which i have been connected M_AXIS port of axis_red_pitaya_adc_0 to S_AXIS_PHASE of dds_compiler_0 as shown image below

ADC_pavel.JPG

modification of ADC
axis_red_pitaya_adc_0 setting:
ADC DATA WIDTH 14
AXIS TDATA WIDTH 32

signal_generator_pavel.JPG

modification of signal generator
DDS compiler setting:
system clock 125MHz
SFDR 84dB
Freq resolution 0.5 Hz

I have tried to feed input IN1 ADC with external signal generator 10kHz.
But the result of output of DAC's frequency is around 5MHz and this frequency is not changed although the external signal generator's frequency has been changed.

BR,
Amin
