Developing the ADC DMA driver

In this section, we will develop three distinct DMA drivers – one for transferring ADC data, another for UART data, and a third for transferring data between memory locations. Let’s begin with the ADC DMA driver.

The ADC DMA driver

Create a copy of your previous project in your IDE, following the steps outlined in earlier chapters. Rename this copied project ADC_DMA. Next, create a new file named adc_dma.c in the Src folder and another file named adc_dma.h in the Inc folder.

Populate your adc_dma.c file with the following code:

#include "adc_dma.h"
#define GPIOAEN            (1U<<0)
#define ADC1EN            (1U<<8)
#define CR1_SCAN        (1U<<8)
#define CR2_DMA            (1U<&lt...
