LPC4078 ADC problem

Question asked by Alberto Ferrari on Jan 27, 2017

Hi everybody,

 

I'm using LPC4078 with LPCXpresso v8.1.4 (build 606).

 

I'm using 3 out of 8 ADC available on the LPC4078 (ADC0, ADC1 and ADC2) in burst mode.

 

It happens that sometimes, suddenly all the used ADCs tell me that the convertion has been done (DONE=1) but they give me 0 as result (even if the input voltage is about 0.5 volt).

 

Attacched you'll find the piece of code I used (here for debug I only check ADC0).

 

Do you have some hints about this issue?

 

Thanks in advance.
