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.

[KKIM.6]

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.

Looks like your code is only initializing 10 channels. To use more than 10 channels, you will need to initialize the other in a similar fashion to the first 10.

this problem is solved by using STM32CubeMX. I think the previous setting has something wrong. Now all 16 channel works successfully and I can save them into the DMA.
