I'm trying to transfer 20-bit ADC data to Filter with referring "Filter_ADC_VDAC Example".
But, data Cohererncy and Alignment is very difficult, I could not success.

   

According to the manual, I set registers as follows,

   

    ADC_DelSig_SetCoherency(ADC_DelSig_COHER_HIGH);

   

    Filter_SetCoherencyEx( Filter_STAGEA_COHER, Filter_KEY_HIGH);
    Filter_SetDalign( Filter_STAGEA_DALIGN, Filter_DISABLED);

   

And, I tried more to change DMA settings,

   

    Swap_Endian, change target address, Filter_STAGEA_PTR or Filter_STAGEAH_PTR ... etc. 

   

Abnormal waveform appears on filter output at which setting.

   

Please tell me the correct settings.

Your demo of
"PSoC 5LP – 16 Bit and 24 Bit Digital Filter Code Examples"
was very helpful for me! 

   

I can make my demo and the demo worked perfectly.

   

Thank you for your help.
