PIC18F4620 Programming problem

[mackrackit]

but on the 18F4620 the port is digital as per the datasheet. If you want to use for ADC, then you must specify it on code.

That is the part you have backwards. You have to make the pins digital.

So... refer to the link I gave you and try

ADCON1=15

Keep reading chapter 19 and look at
REGISTER 19-2: ADCON1: A/D CONTROL REGISTER 1

I could think that it is why led on port a is not turning on, but what about led on port d.

I have to leave to work now but I will defenetaly try your suggestion when I get back tonight.

[mackrackit]

Looking at your code again. The
DEFINE OSC 8
leads me to believe you are using the internal OSC. If so try this

@ __CONFIG    _CONFIG1H, _OSC_INTIO67_1H
@ __CONFIG    _CONFIG2H, _WDT_ON_2H & _WDTPS_512_2H
@ __CONFIG    _CONFIG3H, _PBADEN_OFF_3H
@ __CONFIG    _CONFIG4L, _LVP_OFF_4L & _XINST_OFF_4L

in place of you config line.

Hey guys, tried both suggestions and still not working. My code looks like this:

DEFINE LOADER_USED 1 'Bootloader Used
'@ __CONFIG _CONFIG1H, _OSC_HS_1H
@ __CONFIG _CONFIG1H, _OSC_INTIO67_1H
@ __CONFIG _CONFIG2H, _WDT_ON_2H & _WDTPS_512_2H
@ __CONFIG _CONFIG3H, _PBADEN_OFF_3H
@ __CONFIG _CONFIG4L, _LVP_OFF_4L & _XINST_OFF_4L
ADCON1=15
DEFINE OSC 8
loop:
Serout2 PORTB.7,16468,["Testing123"] 'For PC
High PORTA.0
Low PORTD.0
pause 1000
Low PORTA.0
High PORTD.0
pause 1000
Goto loop

I still think that the problem could reside in MicroCode Studio. I will continue working on it tonight.

Decrease the pauses to pause 1 and see what happens.

[JavPar]

Changed the pauses to 1, but nothing. No change.

How long did you let it run?
