Hi I how to extract the data for multiple input to adc port in lpc2138 . Here is the code for initialization of the adc and tell me how to extract the data for both the adc
void adc_ini(void) { PINSEL1 = 0X05000000; //pin 13 p0.28 and p0.29 adc 0 channel 1 and 2 PCONP |= 0X00001000; //select adc 0 bit 12 AD0CR &= 0X00000000; AD0CR |= 0X00200206; // WITH PCLK 12/(2+1)=4MHZ ADC0 CHANNEL 1 and 2 PIN 13 and 14 AD0INTEN &= 0x00000000; //Completion of a conversion on ADC channel 0 will not generate an interrupt. } void adc_data(void) { AD0CR |= 0x01000000; /* Start A/D Conversion */ while((AD0DR & 0x80000000)==0); //until bit 31 is high (DONE) val = AD0DR; //read a/d data register adc_val = ((val >> 6) & 0x3FF); // Extract AD result }
How to modify for extracting the data from both the data register ?
Thanks in advance
