I need help about my new project. I want to sample from 2Mhz signal with 10Mhz sampling rate about a minutes by a 12bit parallel external ADC (AD9035). since the number of samples will be too many, I need to save them on sd card so that after 1 minutes I use them. now I want to know how can I write my samples on SD with high speed (more that 20 M Byte/s). using DMA, is good idea?
I am pleased if you help me and suggest any algorithms.
I use STM32f407.
