Hi all,

i have a home project which is working perfectly in the breadboard.

However i assembled it in a pcb and the result was a bit different.

I have made 2 pcbs and they both react the same way ( 2 out of 6 leds do not light up with the same intensity as the other in the middle of the code...but they all light up good in the initialization ).


The code is the same for the initialization and the rest:
ex: led1=1 or led1=0

The 2 things i made diferent from the breadboard are:

5v generated from 3v (x2 AA bat. ) using a max1724 ( the breadboard version has 5v from 12v using 7805 )

and

removed all 10k resistors from the pic to leds to increase led brightness.

The leds are conected to ports
led2 var PORTA.6
led1 var PORTA.7
green var PORTB.4 ' bicolor led (green)
red var PORTB.5 ' bicolor led (red)
led4 var PORTB.6
led3 var PORTB.7

The ports that have these strange simptoms are PortA.7 and portB.4

The pic is a 16f88

My question:

Can it be current issues in these ports ? Do these ports have some limitation that can react with the leds ?

Thanks
