Using the ADC of LPC54608.

I have a question about using the adc module in LPC54608.

Would you please give me some help?

1. using two adc channel ,adc0 & adc4.

2.trigger by softare

3. using sequence a only.

4. how to trigger the two channel adc ?

5. how to get the result ,need one by one ,or two channels at the same time?

Hi James,

You want to employ two channel ADC conversion by SW trigger.

I suggest you refer MCUXpresso SDK demo code.

lpc_adc_basic uses polling, assigning one channel with software trigger

lpc_adc_interrupt with interrupt, assigning one channel with software trigger

In the case you need employ two channels, you need get result one by one.

for example SEQA, Channel 0,1

when you initialize ADC, make sure you enable both of the channels in sequence A control register.

when you read result, make sure you read it from the correct ADC channel data register -- DAT0 , DAT1.

Have a great day,
Jun Zhang
