ADC MUXING PROBLEM

Hi,

friends ,

I am using k60D100M that is 100pin IC and mqx is 4.0.2 verstion , i have problem is how do ADC MUXING .

1.i enable adc1 in userconfig .h ,but adc is not measuring.

2.i am using port pin as -->PTB10; in pdf (ptb10 is ADC1_SE14)----> means port pin is -----> AD14 ,so

according this one I changed the phsical adc channel --> ADC1_SOURCE_AD14.

but actually adc is not reading please tell me any other modification required.

const ADC_INIT_CHANNEL_STRUCT adc_channel_param1 =

{

#if defined(BSP_M51EMDEMO)

BSP_ADC_CH_POT1, /* physical ADC channel */

#elif defined(BSP_TWR_K70F120M) || (BSP_TWR_K60N512) || defined(BSP_TWR_K40X256) ||\

defined(BSP_TWR_K40D100M) || defined(BSP_TWR_K53N512) || defined(BSP_TWR_K60D100M)

ADC1_SOURCE_AD14, /* physical ADC channel */

};

regards,

I think you can check the MUX in the register PORTx_PCRn, whether PTB10 is analog.
