Config problem PIC16F886

[Bosse]

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

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

I think, but I'm not sure...
The datasheet says that the upper 2 bits of the CONFIG1 register should read as 1's (even though they're not used), and the same thing for most of CONFIG2.
This leads me to believe that your config word should be $E3ECFFFF when read back off the chip.

Have you got the latest versions of MPLAB, PICKIT2 firmware and software loaded up?

Hi,

Yes, have MPLAB Ver. 8.00.00.00 and updated PicKit2

Shall read bak and see

MPLAB is up to 8.14.
PicKit2...check the website for the latest.

Hi again skimask,

This is my configuration now, will move it to the INC file when there is no warnings.

@ __CONFIG _CONFIG1, _INTOSCIO & _WDT_ON & _PWRTE_ON &_MCLRE_ON & _LVP_OFF & _CPD_OFF & _FCMEN_OFF & _IESO_OFF

Define OSC 8 ' Set Xtal Frequency

OSCCON = %01110001 ' Internal 8 mhz Osc

ANSEL = 0 ' All Digital
ANSELH = 0
CM1CON0 = 0 ' Think ? don't need
CM2CON0 = 0 ' Think ? don't need
ADCON0 = 0
ADCON1 = $0F ' Think ? don't need

Have to try change bit by bit until no warnings from PicKit2

Anything below this line isn't going to have an effect on your CONFIG fuses.
They are 2 separate entities...
And when I said read back, I meant the actual config word data as read back using the PICKIT2, not the data you are trying to push out to the PIC using the programmer.

EDIT: Just checked your CONFIG against the '886/887 datasheet. When reading back the PIC after programming the config word, you should readback $E3ECFFFF, if it's actually being programmed to those values.
