Question
ADC multichannel DMA
with all your help I tried to change multichannel using DMA but I cant able to read the values can anyone please help
ADC_HandleTypeDef hadc1;
DMA_HandleTypeDef hdma_adc1;
UART_HandleTypeDef huart2;
/* USER CODE BEGIN PV */
uint16_t mains=0;
uint16_t battV=0;
uint16_t tsense=0;
uint16_t battI=0;
uint16_t ledI=0;
uint16_t opv=0;
uint16_t batMon=0;
uint32_t getADCvalues[7];
char msg[100];

how to read these values in debugger with Live expression I couldn't get that
