RA6 & RA7 I/O setting on the 16F88

[skimask]

Sorry if I wasn't clear. It works for me without a modified inc file. And the LED's connect from the port pins to ground. Now come on. You knew that didn't you Skimask?

Yep, just quietly pointing out a few 'options'!

If using MPASM use this!!! Use both config!!!

; To use the Configuration Bits, place the following lines in your source code
; in the following format, and change the configuration value to the desired
; setting (such as CP_OFF to CP_ALL). These are currently commented out here
; and each __CONFIG line should have the preceding semicolon removed when
; pasted into your source code.

;Program Configuration Register 1
; __CONFIG _CONFIG1, _CP_OFF & _CCP1_RB0 & _DEBUG_OFF & _WRT_PROTECT_OFF & _CPD_OFF & _LVP_OFF & _BODEN_OFF & _MCLR_OFF & _PWRTE_OFF & _WDT_OFF & _HS_OSC

;Program Configuration Register 2
; __CONFIG _CONFIG2, _IESO_OFF & _FCMEN_OFF

Thanks guys,

Just returned from my vacation!

>leisryan: I tried your suggestion but I get two warnings compiling and the PIC hangs if I program it despite the warnings.

Is there no possible way to set the CONFIG1 (FOSC) bit 4, 1 and 0 to (%1XX00) in the code without disturbing other settings?

Thank you!

You're asking the exact same question as in the original post and you have been given the answers you need to figure out how to do what you want to do.
Just as described in the link in post #19. It will cure almost 99.99999999999999999999% of your (and anybody else's) CONFIG fuse woes...if you read and comprehend the text of the post.

Hi PICante,
Lots of speculation going on here, please give this a try:

@ __config _CONFIG1,_INTRC_IO
OSCCON =126 ' or 1111110 or $7E for 8mhz, 1101110 for 4mhz, 1011110 for 2 mhz . . .

page 40 of the data sheet I am looking at, sect. 4.6.3
Osccon bits 6:4 set osc speed, bit 3 when set makes primary clock, bit 2 set= stable, not set= not stable, bit 1:0 set as 10 = internal R/C as system clock<br>
edit: 1111110 = 126 not 62

Thanks skimask, I have read through what you suggested and all the links and I am sorry to say it did not get me anywhere. I tried a few things without really knowing what I was doing and none of it worked. Most of it was about the PIC18F family which is (in my view) much more advanced compared to the 16F88 which I am trying to figure out. I mean I have to learn to crawl before I can run. Reading stuff that reefer to things way beyond where my knowledge are at this point just messes up my head. I understand that looking from your level of knowledge this might look ridiculous.
