[SOLVED] How to extract ADC data in LPC2368

[bikashh]

Dear friends, i am really confused about how to extract binary data from ADC and how to convert it to the corresponding decimal value.
i've written a program according to my understanding but its not giving any data.

void ADC0Read( char channelNum )
{

DWORD regVal, ADC_Data, ADC_Data1;
int i;
unsigned char binary_data[12];

AD0CR &= 0xFFFFFFFE;
AD0CR |= (1 << 24) | (1 << channelNum);
/* switch channel,start A/D convert */

for(i=0;i<13;i++)
{binary_data='\0';}
AD0CR &= 0xF8FFFFFF; /* stop ADC now */

while((AD0DR0 & 0x80000000)==0);
ADC_Data = ( regVal >> 6 ) & 0x3FF;
for(i=10;i<=0
{
binary_data = (ADC_Data1 = (ADC_Data%10)); //extracting each bit
ADC_Data = ADC_Data1;
i--;
}
binary_data[11]='\0';
read_data=1;
uart0Puts("ADC BINARY DATA->");
uart0Puts((char*)binary_data); /* return A/D conversion value */
uart0Puts("\n\r");

}



thanks in advance

You had already a thread with that subject https://www.edaboard.com/threads/210484/
May I ask why did you open a new thread with the same question?

because that did't solve my query

Yes but this is why your previous thread is still open, if someone can help he will post an answer there.
There are hundreds of threads that don't get solved, can you imagine what it would be like if each user would repost the same question to a new thread because he didn't receive an answer or didn't solve the problem in the previous thread.
