Hi all,

My English is a little poor. I'm sorry if there is a spelling mistake. Please forgive me.

I have a question:

I am using CY8CK-062S4 from PSoC™ 62 MCU. I tried using DMA to transfer two simultaneous ADCs for a total of 512 pieces of data. Normally, these 512 pieces of data should be one continuous signal, but I actually found that it was two signals. The first 256 pieces of data represent one segment of the signal, and the last 256 pieces of data represent another segment of the signal. It looks like this picture.

The manual indicates that 1D transmits a maximum of 256 data. Whether there is a delay at the 256th data position?

This is part of the code,

I felt very confused and desperately wanted someone to help me.

I don't know if I can describe it clearly, but the correct waveform should be continuous like this.
