Bit Banging input to output on PIC16F876A

[mister_e]

This could work, but you'll need to do it all the time in a loop, hence why the comparator or maybe interrupt on change idea came from... and you will need to use Bitwise AND

PORTx=PORTx & PORTx

I haven't investigate the CCP idea, but sure there's something valuable in it. Have a look at Microchip CCP Tricks n Tips document.

Now that's what I'm screamin... Thanks Mister E. This is all running in an IF/THEN loop.
So to recap... My syntax should look like this:

PORTB.6 = PORTA.2 & PORTB.2 ?

And judging from what I read; At 20MHZ, this thing should keep up with a PWM frequency of 3000 with no problem? That makes sense considering the PWM is hardware driven.

Mister E = my hero.

Thanks for your help too Mel.
And everyone else for contributing.
I hope this thread helps someone else that might want to multiplex the two PWM outputs to general purpose outputs.

Now that I'm pretty sure I have the software settled... Has anyone been able to simulate a PIC16F876A with MPLAB's Simulator? What's the trick? I think I have everything set up right, it doesn't complain, but when I run the compile option it opens the PBP editor and then nothing else happens... Anyone?

Ok I did a IDE Compile in PBP(Microcode Studio +) and the simulator started running after I exited manualy from PBP

For some reason it's stuck in this loop in PBPPIC14.LIB

CLRWDT? macro
ifndef NO_CLRWDT
clrwdt
endif
endm
hserinloop CLRWDT? ; Keep Watchdog timer clear
btfss PIR1, RCIF ; Check for char
goto hserinloop ; Loop till char
NOLIST
HSERINX_USED = 1
endif
Return

Is it looking for the watchdog timer?
I'll keep playing with the simulator but this isn't my code, it looks like junk PBP added from the PBPPIC14.LIB?
