Installation sequence

[Demon]

I've had tons of errors trying to compile a blinking LED on a 18F4550 (no problems with 16F628 and 16F877). Folder names were wrong in include members so I've uninstalled everything to start fresh.

I've had a problem in another application that had multiple mods and add-ons; the order of installation had to be followed carefully. So I'd like to make sure I'm not making a similar error here:

1. MeLabs programmer 3.12 (disquette)
2. PIC BASIC Pro compiler (CD)
3. MicroCode Studio Plus (CD)
4. Lab-X (disquette)
5. PIC BASIC Pro upgrade 2.46 (disquette)
6. PIC BASIC Pro upgrade 2.46a (download)
7. MicroCode Studio Plus upgrade (online)
8. MPLAB Tools v7.21 (download)
9. EasyHID (download)

Does that look ok?

Ok, things are getting worse. I was just going down my checklist and reinstalling everything and I got a snag at update 2.46a. I get this error:

Cannot update version 2.46.
E:\PBP\INC\M16F684.INC: unknown version.

Any idea what's going on?

__CONFIG has been deprecated for PIC 18F devices. Use directive CONFIG.

According to dictionary.com that means __CONFIG is obsolete and now replaced by CONFIG. It's not just a matter of replacing the text, that didn't work. Is there new syntax? How would you write this statement now?

@ __CONFIG _CONFIG1H, _PLLDIV_5_1L & _CPUDIV_OSC1_PLL2_1L & _USBDIV_1_1L

[Demon]

Jeez, now I have problems finding includes in MicroCode Studio. The file pathnames are not right...

Robert
:(

[Demon]

Well, found the answer to some problems myself. :( I editted the pathnames in the includes and libs and things work further (added disk and full pathname).

I'm still faced by that deprecate warning, still no idea how to get rid of that.

And then there is one last ERROR[118]: OVERWRITING PREVIOUS ADDRESS at line 50 of the ASM file to figure out.

Robert
:/

[mister_e]

Look at that !
http://www.picbasic.co.uk/forum/showpost.php?p=13087&postcount=6

for the over writre blah blah just comment the default config fuses in the .INC file in the PBP folder

[Demon]

Ok, this is funky. The 1st thing I did was to go look in the FAQ for help on these issues and I only had 2 threads listed. I just did a SEARCH through the forum and found this thread:

Presetting Configuration Fuses (PIC Defines) into your Program

But if I go look in FAQ again, it's not there, always the same two threads? Anyways, Mister_E posted the answer to why I get the OVERWITE message.

Now if I can just find the answer to those pesky DEPRECATE warnings.

Robert
:)

[Demon]

Thanks Steve.

(don't you hate posting at the same time as someone else?)

Robert
:)

P.S.: STEVE, GET YOURSELF A HOTMAIL ACCOUNT AND EMAIL ME.

[mister_e]

Mr Demon.. open your eyes i already post a link above ;o)

EDIT: Glad to see you found it! I already have an hotmail account... without ANY KIND OF easy to hack Messenger or whatsoever. Videotron is working now..!

[Demon]

Steve, like this? I kept all the values so it is easier to change them around later.

If this is correct, it would make a good addition to one of those Configuration threads in the FAQ.

Robert
:)

[Demon]

Steve, I must have something wrong in the config switches above. The LED is blinking more than twice as fast as it should. This is the test code:

'define LOADER_USED 1
LED1 VAR PortD.1
START: HIGH LED1
PAUSE 1000
LOW LED1
PAUSE 1000
GOTO START
Finish: end

I am using a 20MHz external oscillator. I would like to be able to use slow speed USB on this device later. Do you see something I missed in the config?

Robert
:)

[mister_e]

you just need to modify the .INC in the PBP folders. My own file looks like that

Do you still use the Bootloader? Did you also use the DEFINE OSC 20?

How about your current one?

[Demon]

You can't just comment out default values. You must assign them something, somewhere, no?


Do you still use the Bootloader?

Nope.


Did you also use the DEFINE OSC 20?

Nope.

This is my latest code, same acceleration problem:

I'm programming the chip via the MeLabs serial programmer.

Something else is acting weird. The MCLR pin seems to be held by the programmer for some reason. I have to unplug the MCLR wire to the programmer in order to be able to use my RESET button.

It works properly for an 16F877, but not for an 18F4550.

Robert

[Demon]

D'uh, nevermind on the acceleration thingy. I had to add DEFINE OSC 20.

I thought CONFIG PLLDIV = 5 in the default configuration bits set it at 20MHz, apparently not.

< Divide by 5 (20MHz input) >

[bioeng-mostafa]

Hello every one
i want help of you to send to me or help me to find the two files
1-18f4550.inc
2-18f4550.bas
thank you

[Bruce]

Hi Robert,

CONFIG PLLDIV = 5 is a "config word" option. This sets the PLL prescaler to
divide the 20MHz primary osc input by 5. This is required when using a 20MHz
primary osc because the input to the 96MHz PLL must always be 4MHz.

DEFINE OSC 20 is different. This is used internally by PBP to adjust timing of
PBP library routines to the 20MHz primary oscillator.

bioeng-mostafa,

If you don't have the 18F4550 device header files, then you need to update
to the latest version of PBP. Version 2.46 introduced support for the 18F4550
series.

Just having someone email you device header files does not guarantee you'll
be able to use the new device. There are more to some PBP updates than
additional device specific header files.

[bioeng-mostafa]

hello
plase any one have PBP Version 2.46 introduced support for the 18F4550
send it to me or tell me how i can get it

[bioeng-mostafa]

Please don't ask for people to make and send you Pirate copies, get your own legally like the rest of us have had to.

If you need an upgrade, go back to your original supplier or MeLabs directly.

[Squibcakes]

What software do you lot use to program the 18F4550?

I've always used IC-Prog with my JDM programmer to program other chips ok - but it looks like IC-Prog doesn't support this chip yet.

I've tried winPic800 - but that doesnt detect the chip.

Help appreciated.
Squib

[mister_e]

over the year i discovered and confirm that what you invest in really worth if you use it daily. Even if you spend 400-500$ or more

simple calculation
OriginalPrice/(DaysOfUseInAYear*Years) ... after 1-2 years you'll discover than less than 1$ a day really worth all time wasting if XYZ odd problem happen due to the limited support.

Picstart is still workable but i don't recommend it now. It have still some problem on some device. All problem are solved here using BK precision 844a another Elnec relabeled). Work 100% of the time. The software upgrade is free and support by far more than only PIC.

Now if you plan to program only PICs... Melabs EPIC or Microchip ICD2 are some great tools too. At least often mentionned here and on other forum.

Those freebies like JDM & Pals are probably good for older device.. 16F628, 16F84... but come-on and give a break to those poor guy who develop FREE software around that like IC-Prog, WinPIcProg, PonyProg and how many others.

You're serious, use serious stuff

Sorry, it's my own and single opinion. Please, no flames.

[Squibcakes]

Sorry, found my problem.. wrong pinout in my Connector! Ahhhhh!!!

$2 JDM cheapy saved the day again!!

You're right... Hahahaha. I should spend the bucks and get a specialist programmer... maybe if the tax man is good to me this year I'll get one.

Cheers :)

[mister_e]

As i said, if you're a serious developper or work most of your time 'round PIC and other programmable IC (eeprom include) the investement and support really worth... at least to me.
