Config problem PIC16F886

[Bosse]

Hi Skimask,

Thank you !

Now it starts working, have changed the config in the 16F886.INC file and moved the configuration over to the real program. But still have the warning from PicKit2.

Have to work on and make some small changes and see if the warnings will go away.

I'm not proffessional, but have learned very much from this forum and are very greatful for all your help.

Thank you ALL

Probably means that you typed something in wrong, missing a space here or there, have an extra ' character, maybe a " character in there somewhere that shouldn't be...

Post the real CONFIG part that you're using. We can guess at your problem all day. Could be that the tire pressure is low...we'll never know...

Just got back from dinner . . . That is why I asked him to post the .inc file and first 8 lines or so, to see if he introduced an extra character . . .

we can hope . . .

Hi skimask, Joe and Darrel

Can not find out how to find out about the CONFIG word. Have comment out the CONFIG word in the program. using MPASM assembler. Now I'm really confused. Have been lucky with my other programs for other Controllers, that I can see now.
Really wants to find out how to configure CONFIG word for 16F886.

I wants to have 8 MHz Internal Oscillator, my PCB have 4k7 resistor to MCLR pin so think MCLR have to be ON?
Also want ALL I/O to be DIGITAL.

Have printed out the INC file from the MPASM directory and the PDF file for 16F886 from MicroChip. Have much to read, but if I understand all???

What can I do to get it work?

Include a short version of the program.

All the Best

Can not find out how to find out about the CONFIG word.

The config fuses are explained in the 16F886 datasheet in the 'Special Features of the CPU' section.

Have comment out the CONFIG word in the program. using MPASM assembler.

If you comment them out in the 16F886.INC file in the PBP folder, you need to put them in your main program.
If you don't put them in your main program, you can temporarily/permanently set them in the 16F886.INC file in the PBP folder.

Really wants to find out how to configure CONFIG word for 16F886.

And again...if you read, and re-read, and re-read, and heed, this thread:
http://www.picbasic.co.uk/forum/show...ght=presetting
You will understand what needs to go where...
Get the list of available/recognized config fuses settings from the 16F886.INC file in the MPASM folder...just like the thread says to do...

Hi skimask,

Thank you very much for all your help, now I will change the config in the INC file.

Wish you all the best

Ya Know, I would only add an <b><font color=red> ; </b></font color> there. What I would do is save the configs you want saved as a file, call it 16F886 Setup and open it for each new project, then when you get ready to compile just save it as your new project's name: MyNewProject.BAS

HI BOSSE,
Time to ask, what is / is not working? Your file compiles nicely here, only changes I see are as follows: add, OSCTUNE = %00000000 ' SET OSC TO CALIBRATED VALUE
VRCON = 0 and change to OSCCON = %01110101 , these may in fact do nothing differently, but I would try them. Does your circuit come alive and do anything ? Have you tried adding a heartbeat code just so you can see if life exists? Simple LED works wonders.

Hi skimask,

Have changed to INTOSCIO in 16F886.INC and have the following config in program

OSCCON = %01110001 '; Internal 8 mhz Osc
'OSCCON = %01100000
ANSEL = 0 '; All Digital
ANSELH = 0
CM1CON0 = 0
CM2CON0 = 0
ADCON1 = $0F
ADCON0 = 0

TRISA = %00000010
TRISB = %00001111
TRISC = %11100100

The program will not work perfect yet ???

That's the register setup, not the CONFIG fuse setup

Hi Joe,

Forget to tell you the Warning from PicKit2.

Warning: Some configuration words not in hex file.
Ensure default values above right are acceptable.

Configuration 2FF9 0700

Bosse

According to that CONFIG word, and according to the PIC16F886 datasheet, this is your configuration:

DEBUG mode is OFF
RB3 is I/O
Fail Safe Clock is ON
Int/Ext Clock Switching is ON
BOR is ON
CPD is OFF
CP is OFF
RE3/MCLR is MCLR
PWRT is OFF
WDT is ON
Oscillator mode is INTRC, ClkOut on OSC2, R/C input on OSC1
All Write Protects are Off

What's not right?
I'd be betting it's your spelling of INTRC. Check the 16F886 INC file in the MPASM directory to figure out how to spell it so the assembler is happy.

Hi again skimask,

Have also changed to MPASM assembler and it works better now
