How to use ADC channel 10~16 in the Nucleo-WB55 board? The 1-9 is successfully working but the ADC is not working from 10.

I'm designing multichannel ADC using scan conversion mode.

Using HAL_ADC_Start_DMA code, the 1~9 ADC is easily saved in the DMA but. from 10, the ADC is not working and I cannot see any UART communication data.

How to use ADC channel 10~16 in the Nucleo-WB55 board or is there anything I missed?

In addition, is there any exam sending the row data from the WB55 board to the PC through Bluetooth?

here is the code.

#include "main.h"

#include "stm32_seq.h"

#include "string.h"

#include "stdio.h"

ADC_HandleTypeDef hadc1;

DMA_HandleTypeDef hdma_adc1;

HAL_StatusTypeDef ret;

UART_HandleTypeDef huart1;

ADC_ChannelConfTypeDef sConfig;

float value[16];

uint16_t DMA_value[16];

int main(void)

{

HAL_Init();

MX_USB_PCD_Init();

MX_APPE_Process();

HAL_ADC_Start_DMA(&hadc1,(uint32_t*)DMA_value, 16);

while (1)

{

HAL_ADC_Start(&hadc1);

HAL_Delay(100);

printf("%.d\t %.d\t %.d\t %.d\t %.d\t %.d\t %.d\t %.d\t %.d\t %.d\t %.d\t %.d\t %.d\t %.d\t %.d\t %.d\t \r\n", DMA_value[0],DMA_value[1],DMA_value[2],DMA_value[3],DMA_value[4],DMA_value[5],DMA_value[6],DMA_value[7],DMA_value[8],DMA_value[9],DMA_value[10],DMA_value[11],DMA_value[12],DMA_value[13],DMA_value[14],DMA_value[15]);

fflush(stdout);
