Config problem PIC16F886

[Archangel]

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...

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 . . .

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...

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...

If you're going to put the config fuses in your program, comment out the above line

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 Joe,

Thank you for your help. Was working yesterday to 06.30 in the morning, so today I have not tried out the new settings. Will do it tomorrow and belive it will work now. Have tried with LEDs and sometimes 2 LEDs lights when only one should. Will send you info about my progress tomorrow.

Many thanks again ALL of you

Hi everybody - especially you how have helped me, MANY THANKS!!

Now it is running nice - still a warning from PicKit2 - Configuration 23EC 0700

But can not see any problem when program runs - have hardtested all functions and NO problem to see.

All the Best to you all

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.
