Hi guys,

The blow pictures shows my circuit where Iam trying to transfer my ADC sampled to the PC through the DMA.

My question is, how can I find my data in memory and put it in separate buffer.

what functions do I need to use to receive the data from the ADC. I put the functions that I used till now.I2S and DMA.pngprog.png

Hi,

I am confused why use I2S with ADC result transfer.

The ADC module could trigger DMA when conversion done.

Please refer MCUXpresso SDK software for LPC54608, which provides [lpc_adc_dma] demo with below path:

C:\nxp\SDK_2.3.1_LPCXpresso54608\boards\lpcxpresso54608\driver_examples\adc

Wish it helps.


Have a great day,
Mike
