DTMF decoder
Right, m comes out of the blue, just a byte variable as demonstration that inclusion of m=m+1 causes failure.
How do you use code tags when posting code?

DTMF decoder using 16F628A
I have new coding problem, using TMR0 I do not understand........put simply
loop1:
if intcon.2 = 0 then loop1
intcon.2 = 0
clicks=clicks+1
if clicks >=1900 then
clicks=0

I have now set in my PBP code, @ DEVICE pic16F628, MCLR_ON
This still doesn't allow chip to reset properly, only whilst MCLR is held low does PIN1 stay LOW. If I remove the 5V power completely it...

My DTMF software works fine using 16F628A.
I can make PIN1 go HIGH and PIN1 go LOW; what doesn't work is MCLR?
I was expecting MCLR, on grounding, to reset the micro and make PIN1 LOW.
It does...
Was DTMF, now TV IR controller.
DTMF now working satisfactorily. Thanks for all your help.
Next project, how to emulate TV IR remote function?
I want to replicate two Video remote control functions viz Fast Forward and Play. ...

DTMF code
Why doesn't
pincode1 = PORTB && $0F...work in PBP ?
When PORTB lower 4 bits are 0010 && 00001111 I should get 0010
I get $9C...????
How weird?
Bob, from across the road, has gone on his...

Hello Doggitz
I am just starting out on a DTMF for remote control via telephone.
I am using 8870 DTMF receiver and PIC 16F628 to do the work.
So far DTMF receiver works fine but as usual the...
