[saidutt]

hi friends,

i am new to ARM micro-controller.i need to write ADC code for data logger unit.
so, i am working on it .the data from ADC( ADC0 and ADC1) is not been displayed on hyper terminal .controller is been waited for forever ( AD0DR1, last bit to be set as '1' =31 bit).

	void adc_1_channel2()
			{	unsigned char out,c1[]="channel 2:";
				unsigned int i,val;
				for(i=0;i<11;i++)
				send_data(c1[i]);
			//	PINSEL0&=0x00050000;
			PINSEL1 = 0x01000000;
			 AD0CR   &= 0x00200602;
			 AD0CR|=(1<<24);  
			   // AD1CR=0x00250604;
			//	AD1CR|=0x01000000;
				do
				{//val=AD1DR2;
				val=AD0GDR;
				}
				while((val&0x80000000)==0);  // going into infinite loop.
				out=(val>>6)&0xff;                //data is not displayed
				hex_to_decimal(out);

			}

data is been not displayed.
i coudn't identify the error.

so please help me out
