while(1)
{
/* scan channel 1 */
LPC_ADC->CR = 0x00000601; // select channel one
LPC_ADC->CR = (LPC_ADC->CR & 0x0FC1FFFF) | (BIT_24); // enable start conversion
while(!(LPC_ADC->STAT & 0x00000001)); // wait while conversion
// read the value of channel 1
LPC_ADC->CR = (LPC_ADC->CR & 0x0FC1FFFF) & (~(BIT_24)); //disable start bit is it necessary here
/* scan channel 2 */
LPC_ADC->CR = 0x00000602; // select channel one
LPC_ADC->CR = (LPC_ADC->CR & 0x0FC1FFFF) | (BIT_24); // enable start conversion
while(!(LPC_ADC->STAT & 0x00000002)); // wait while conversion
// read the value of channel 2
LPC_ADC->CR = (LPC_ADC->CR & 0x0FC1FFFF) & (~(BIT_24)); //disable start bit is it necessary here
}
