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.
Solved! Go to Solution.

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.
