I'm using two analog inputs, the first with a LDR and a resistor of 10k
Ohm, connected at P9_39 (AIN0), and the second connected at P9_38 (AIN3).
When the lights are down, the measure of LM35 works very well, with a low
distorction, +/- 0.2 ºC.
But when the lights are on, the measure of LM35 starts to float, about +/-
1 ºC.
I have tried to put a 4.7nF between GNDA_ADC and AIN3, but the distorction
continues.
I asking for help to diminish this distorction when the lights are on.
