Trying to migrate to 18F..

[Glenn]

I been using 16Fx for some time now, and now I wanted to use something more powerful, I looked up a nice PIC, 18F4620, and checked that it was PBP compatible, yes, and ordered.

First I tried to just recompile a program written for 16F877A, since they are basically pin compatiblie, and it was a very easy program.

BUT.. pbpw says that MP does not support 18F family and that I should use mpasm instead.

First problem, mpasm does not exist.. I reinstall the latest version of mplab IDE, still doesnt work, google a bit, set the path to include mpasm catalog, but still no go, there are no mpasm.exe ? ..but there are a mpasmwin.exe and in the documentation it says that its supported too, so I tried..

Fail..

ANd I have no idea why..

First I thought it was the config switches, but after playing around with them it doesnt get any better :(

Any idea what I have missed ?

I wrote an even simpler program that would just blink a LED, and get the same errors..

..I dont like mpasm :(

[Glenn]

Hmm, looking in the tst.asm I can see that all errors points to my config lines :(

Its REALLY REALLY stupid that the config lines are in different formats between mp and mpasm :(

Theese are the config switches I used the last time.. but I tried at least 20 more variants..

@ __CONFIG _CONFIG1H, _OSC_HS_1H
@ __CONFIG _CONFIG2H, _WDT_OFF_2H & _WDTPS_512_2H
@ __CONFIG _CONFIG3H, _PBADEN_OFF_3H
@ __CONFIG _CONFIG4L, _LVP_OFF_4L & _XINST_ON_4L

This was my original attempt after reading the docs..

@ __config _OSC_HS &_LVP_OFF &_WDT_OFF

..And yes I am using a external xtal @24MHz, and yes I know that there are a internal osc in this pic.

[mackrackit]

Did you comment out the correct lines in the inc file?

[Archangel]

Did you comment out the correct lines in the inc file?

From the error I would say no. Note: you will have to comment them again after a PBP upgrade too.
In case you are not aware what Mackrackit is talking about, or if someone new to PBP reads this, the file Mackrackit is refering to is the 18f4620.inc file located in the root directory of your PBP installation. If you already know this, great someone new who sees this might not.

[mackrackit]

Good point Joe.
So.....
http://www.picbasic.co.uk/forum/showthread.php?t=543

[Glenn]

Aha, so I cannot really override settings with statements in my sourcecode, as I can with pm ?

..Since this is a 18F device PM isnt supported anyway, so I guess I can change as I like in the file.

Now I just changed the .INC file to my needs, and it worked. (well, at least it compiled without warnings, I never uploaded it to my pic)

Can I just comment out everything there, and then ALWAYS set the defaults in each sourcecode ? ..then I have to write it mpasm style ofcourse, but since it's a 18F device I will never use PM for it anyway. (If ME-labs doesn't release a version of PM supporting 18F.. wich I really would love if they did.)

..As I said, I never use neither 18F devices or mpasm before..


Anyway, Thanks for the help, without this forum I probably would have given up on PBP a long time ago.. now I nearly convinced several guys at work to start using it too ;)

[mackrackit]

You will not even notice MPASM after awhile. For that matter I have never used PM....

Yes to setting the configs in source. But only comment out the actual config lines in the inc.
The other stuff is needed no matter what.

[Glenn]

Well, I'm back again...

Last time I got so tired of it so I quitted that project and started with other stuff instead, PIC16F based, coz there I never get any of those troubles.

*Every* single time I try to use a 18f pic I seriously considering to get another hobby, I really really really HATE mpasm.. it NEVER f**ing work.. I dont want to know how many hour I been using on this crap :(

I write a program, compile it with like 87665 errors, trying to get the config bits correctly (wich always works on 16f and mp) and after some hour or so I MAYBE can compile it witn just warnings, and then I upload it to the pic, and it does NOT work..

I REALLY try to read both the includes of mpasm AND microchips datasheets, but still, I never get it right.. I try to comment out all config directives in the PBP include (tor the correct pic), or sometimes just the ones I want to change.. but nonono.

..If I at that point change the config bits to "mp-style" and compile it for a 16f (with mp), it ofcourse works directly with no problems... so its NOT my code, its the configbits.

The pic I try to use now is a PIC18F2520 and since my long advanced program (that works perfectly fine on a pin compatible 16F876A) OFCOURSE didn't work, I created a reeeally simple short program that just blinked two LED's..

This compiles with no errors, but warnings (about deprecated __CONFIG for example)

..I have a pulldown on MCLR and the LED's are connected with resistors.. I want to use the internal oscillator, and no WDT.

all __CONFIG statements in the PBP 18F8520.INC are commented out.

Can anyone point me to somwhere this are explained ? or tell me what the problem is ?

[Glenn]

..I can add that this is one of MANY MANY different config settings I have tried..

It can be confusing to switch. It looks like you are using the wrong configs for the PIC18F2520.

You should be looking at the mpasm folder called 'MPASM Suite' (at least that is what mine is called), and then look at file: P18F2520.INC

At the bottom of that file, you will see all your options, like this:

Powerful devices need to configure more registers ... that's it !!!

Glen,

Probably a typo:

You said

"..I have a pulldown on MCLR and the LED's are connected with resistors.. I want to use the internal oscillator, and no WDT."

A pulldown (tied to ground) on MCLR will keep the pic from working. I assume, since you said your PIC16's programs function its just a typo and you are using a "pullup" resistor (tied to Vcc) on MCLR. Don't give up!

[Archangel]

Hi Glenn,
Couple of minor details: In Assembly the ' apostrophe does not work to make a line a comment, you MUST use the semicolon ;
now this line:


..I have a pulldown on MCLR and the LED's are connected with resistors.. I want to use the internal oscillator, and no WDT.

<b>I HAVE NOT</b> checked the data sheet, If you use the MCLR pin as an output, <b>MOST PICS </b>have an Open Collector output, which requires a PullUp resistor, as they can only pull down.
Try this for your osc:
__CONFIG _CONFIG1H, _OSC_INTIO67_1H & _FCMEN_OFF_1H & _IESO_OFF_1H ; enable int osc, disable failsafe osc enable, disable internal external switchover
<b>Ok now I have looked at the data sheet,</b> as for the MCLR pin This is from the data sheet:

The fourth pin of PORTE (MCLR/VPP/RE3) is an input
only pin. Its operation is controlled by the MCLRE Configuration
bit. When selected as a port pin (MCLRE = 0),
it functions as a digital input only pin; as such, it does not
have TRIS or LAT bits associated with its operation.
Otherwise, it functions as the device’s Master Clear
input. In either configuration, RE3 also functions as the
programming voltage input during programming.
INPUT ONLY

[Glenn]

scalerobotics: Yes, I have looked at that, but still, for example that include mentions:

_BOREN_OFF_2L

..But if I include that in my PBP program I get a "symbol previosly not defined" error from mpasmwin:

Error[113] C:\PBP\LTIMERT.ASM 70 : Symbol not previously defined (_BOREN_OFF_2L)

acetronics: Same with that, a good example is the _BOREN_OFF_2L that does not work ?

Just an example of working configbits for internal oscillator that works on 20MHz would be great, then I could try things after that, but now I cant even get the damned thing to run..

Oops, yes, its connected to Vcc with a 10k resistor :)

Well, if the ' is before the @ it should work ? or ?



Try this for your osc:
__CONFIG _CONFIG1H, _OSC_INTIO67_1H & _FCMEN_OFF_1H & _IESO_OFF_1H ; enable int osc, disable failsafe osc enable, disable internal external switchover


This gives me..

..And the usual "deprecated" warning about __CONFIG.

32 mhz is your speed limit using PLL and internal osc.
Set it up in OSCCON register

Well, at maximum I presume ? actually I don't really understand what they mean exactly in that part of the datasheet, I would belive that I set one speed on the oscillator, and then the PLL multiplies it ? then 8x4 would give 32Mhz ? ..Ofcourse that would give me troubles to get excactly 20Mhz then, but still, it would work I think ? (but for exampe, "pause 1000" would not be one second)

Anyway, I could use another clock frequency too, the main reason to use 20Mhz is that I tried the same program on a 16f PIC with no internal oscillator, and then I used a 20Mhz xtal.

Hi Glenn,

Newer versions of PBP include w = -230 in the .INC file that gets rid of the deprecated
warning.

I.E. a new version .INC file looks something like this if you have the default config settings
commented out.

[Glenn]

Hmm, strange. I thought the "version 2.46" was a bit suspect, so I looked one time more, and found a "18f2520.inc.org", which probably is the correct file, and the other is something I cut'n'pasted in from someone else ?

That one looks like:

Still bot 2.50b, but 2.47, but maybe the includes only get updated when needed. (sounds logical)

Also I didnt do a clean install, I upgraded from an old version.

[Glenn]

Changed from the old include to the new one, and to my surprise the code compiled without errors ?

..However, it still doesnt work :( no flashy LED's :(

[Bruce]

It would really help to know which PIC you're compiling for, and which compiler you're
using....:o

Are you compiling for an 18F2550 or 18F2520?

Are you actually compiling with PBP 2.50b, 2.47, 2.46...?

[Glenn]

I probably shouldnt try to do anything serious at the middle of the night :)

The pic is a 18F2520, and I have no idea why I choosed to post the include for 2550 :) ..probably too tired :)

PBP is version 2.50b, HOWEVER the include states "Version: 2.47", I GUESS that this is normal however since I did a standard installation, but I installed it over my old installation, which I dont remember what version it was, but it can have been 2.46 or 2.47.

[Bruce]

It's porobably 2.5. Not all include files are updated with each new version.

If you try the example I posted above, with config settings in the code, then you'll need to comment the config settings in your 18F2520.INC file just like you did with your 18F2550.INC file.

Then get some sleep...:o

[Glenn]

Yes, I guess so too, no need for changing the version of the includes if nothing in them have been changed.

and I comented out everything in the correct include, now it looks like:

END


..And it compiled with no errors.

The setup is just a PIC18F2520 with pin20 connected to +5V, 8/19 to gnd,
a 10k resistor from pin1 (MCLR) to +5V, and two LED's connected via resistors
from pin 26 (RB5) and 25 (RB4) I also added two cap's between Vcc and gnd,
one 1uF and one 100nF.

I also have a pickit2 connector wired up to usual pins.

..And now I'm going to the bed :)

[Glenn]

I'm starting to suspect that this PIC is broken.. but its a bit strange that it's possible to program and verify it anyway.

I'll see if I can buy another one tomorrow, but I dont think my local supplier have it in stock..
