how to configure several saadc channels of nRF 52810

[james]

Hi,

 I need to use 6 saadc channels to sample voltage on my project. The saadc channel 0 could be configured to connect different inputs(ANI0~AIN7).But I try to configue other saadc channel,it doesn't work.I have no idea for that.There is my code and the result of saadc register below.

Pretty sure that the SAADC example in the SDK uses 3 channels ... ?

How to properly post source code:

        uint32_t ba_err_code;
			 int16_t batteryTemp[4] = { 0 };
			 int32_t batteryLevel = 0;
			 uint8_t checkStatus = 0;
			 uint8_t batterPercentTemp;
			
			 //InitAdcChannel( ADC_CHANNEL_SIX, LOW_TEMPERATURE );
			 nrf_saadc_channel_config_t channel_config = 
       ADC_DEFAULT_CHANNEL_CONFIG_SE( NRF_SAADC_INPUT_AIN0 );
			 
			 nrf_saadc_channel_config_t channel_config1 = 
       ADC_DEFAULT_CHANNEL_CONFIG_SE( NRF_SAADC_INPUT_AIN1 );
			 
			 ba_err_code = nrf_drv_saadc_channel_init( 0, &channel_config );
			 APP_ERROR_CHECK(ba_err_code);
				
			 ba_err_code = nrf_drv_saadc_channel_init( 1, &channel_config1 );
				APP_ERROR_CHECK(ba_err_code);

				}
			 else
				{
					 checkStatus = 1;
