Learning to walk again. (18F46J50 configuration)

[Darrel Taylor]

We should call that a 543 error.

OK, scratch that.
That chip is one of the casualties of the __CONFIG has been depricated change.

The old __CONFIG's won't work.
Which means you can't put the configs in your program.
It has to be done from the 18F46J50.INC file in your PBP folder.

Thanks Darrel,

That explains why my forehead is so sore.
I've been pretty successful at setting up CONFIGs for 16F chips, using the good advice and techniques in Melanies excellent thread that you referenced.
But no matter how many @'s and underscores and (or lack of) that I tried, I always get errors with this danged 18F46J50!

THANK YOU for pointing out that it can't be done from within my program with this chip!!!! (well, that's damned inconvenient, ain't it?)
I'll whittle away at it some more and post my results later.

SO... does that mean that I've now got to maintain individual INCLUDE files for every project that uses this chip but doesn't use the same settings? THAT would totally suck...


Thanks much!

Byte_Butcher,

Ok, I am just curious here. What type of programmer are you using? I never need to include the "__CONFIG" or the "@ DEVICE pic16F628, INTRC_OSC_NOCLKOUT" lines in my programs. I use the U2 Melabs programmer and it comes with software that takes care of all of this for you. You just change the settings in a pulldown menu and that's it. It's a lot easier and that way I don't make mistakes like forgetting to enter a setting or spelling issues, etc. I attached a picture of my programmer with settings for a PIC18F4550 for a USB project that I'm currently working on.

Darrel,

Will this software work for a 18F46J50? Or, do I need to use the inc file like you suggested to Byte_Butcher? Thank you.

What about something like this in the code?

ASM
    CONFIG XINST = OFF
    CONFIG FOSC = HS
    CONFIG WDTPS = 512
    CONFIG CP0 = OFF
ENDASM

Byte_Butcher,

Robert, I''m using the PICkit 2.
But the melabs programmer is starting to look pretty handy...

Anyone else have any comments about using the melabs vs PICkit programmers?

I've got what I think seem like intelligent configuration settings put into my 18F46J50 include file, but I STILL can't get an LED to blink. I don't think the chip is running at all.
I'll post my code and configs later, after I've fed cats and taken care of some sunday morning chores.

I have not used the melabs programmers, but over the years here it seems like one of the problems has been with the configs being set via the software. Problem solved by turning that feature of and learning how to set the configs in the *inc or in code space.

You have a PicKit2, just stick with it.

OK, all I'm trying to do is flash 2 LEDs on ports B.4 and D.0 of the 18F46J50.
It's not working. Not only do the LEDs not light, but the chip doesn't even seem to be running. All of the output pins seem to kind of "float" like they were high impedance inputs, and there's NO clock out on RA.6.
I kind of get the feeling it's not running at all. I DO have 3.26 volts on both Vdd pins, and 2.44 volts on the Vcap pin (internal regulator), so the power is on.
I'm guessing that there's SOMETHING that I haven't set correctly, but I haven't found it yet.

Here's my CONFIG goodies. I'm trying to use the internal OSC with an output on RA6 so I can see if the clock is running.

;****************************************************************
        NOLIST
    ifdef PM_USED
        LIST
        "Error: PM does not support this device.  Use MPASM."
        NOLIST
    else
        LIST
;;;        LIST p = 18F46J50, r = dec, w = -311, f = inhx32
        LIST p = 18F46J50, r = dec, w = -311
        INCLUDE "P18F46J50.INC"	; MPASM  Header

	CONFIG XINST = ON
	CONFIG STVREN = OFF
	CONFIG PLLDIV = 2
	CONFIG WDTEN = OFF

	CONFIG CP0 = OFF
	CONFIG CPUDIV = OSC1

	CONFIG IESO = OFF
	CONFIG FCMEN = OFF
	CONFIG LPT1OSC = OFF
	CONFIG T1DIG = OFF	
	CONFIG OSC = INTOSCO  ;Internal OSC, with output on RA6
	CONFIG DSBOREN = OFF
	CONFIG DSWDTEN = OFF



        NOLIST
    endif
        LIST
BLOCK_SIZE	EQU	64

And here's my program.
I was hoping that this would set the set the internal OSC to 8MHz, disable all the peripheral stuff, and flash some LEDS on ports B.4 and D.0
No luck so far.

Does anyone have any clues they could toss my way? In the meantime, I'll go RTFM some MORE in hopes I can make sense of all of those registers eventually...
