read adc in 2 inputs (by Alex)
hello, i want to read 2 adc inputs, RE0 and RE1 of pic 16f877a, both using potentiometers, but when i read RE0 there is a little variation in RE1, i have read that in happens due to both adc pins are very close to each other, so, is there a ladder where while i read in RE0, RE1 doesn´t ride and viceversa?

I never have heard of that, your description is very vague, no schematic, no potentiometer values, power supply stabilization that forms the Vref etc...

It is much more likely that the hardware is the cause than the pin distance of the chip.

comprobado y funciona muy bien (by Calubert)
por Alex, te adjunto una escalera con pic887 probado y funciona correcto, lo e probado toda la programación es con LDMicro.
y el LCD se comunica por UART (TX RX)
