Hi

I used lpcxpresso54608_driver_examples_adc_lpc_adc_dma and the example work only if I have to tranfer to external memory only one acquisition form ADC

My question is :why to use  kDMA_MemoryToMemory in the function DMA_Prepare_transfer instead of Peripheral to memory? DAC register is not memory. After every single transfer from memory to memory the source address and the destination address are incremented, but AD address register must be always the same

 

Best Regards
