RT1052 ADC+DMA circular transfer

[Loadd]

I'd like to transfer ADC data to a buffer by dma. I configure dma already , but dma works only one time. It stops after first transfer. I want to transfer every time ADC complete a conversion . I can't find any example code about this amplication. Dose anyone know how to do"

Hi,
Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
According to your reply, you want to implement a similar application as the post shows.
For the RT1052, it definitely can make it, as the eDMA supports the scatter-gather feature which enables it to work in Ping-Pong mode like the above post shows.
In further, the PIT timer can trigger the ADC as the SCT module does too.
Have a great day,
TIC
