A little DTMF help

[Travin77]

I apologize for patronizing you. I didn't post the extra code because it is the same as before I thought. I mearly did as you had mentioned. I will not ask for your help anymore. Thanks for the help you have given me up to this point. You have pointed me in the right direction. I will continue to post my updates, in an effort maybe to help others. Thanks.

Hi Travin,

dont be shocked by me !

dont stuck your head into the sand....

I want to give you help to reach the goal, but you have to learn !!!!
I think there are some gadgets in your circuits, we don't know...
You have no problem in the if-then-part, you have a problem in the communication and timing with your mc- and isd-parts !
You try to write lousy code to talk to them. You have to write subroutines which communicate in the only right way with the chips and you have to use them in your little programm !

I don't think your little problem need such a lot of postings...

I guess I am just confused here. The led subroutines are merely a visual aid for the debuggin process. I have about 10 different program written for this contraption. I started with each section of the main program until it worked correctly. Then I moved to the next section and so forth. When I put them all together, they don't work. Like for instance, in the previous post, the branch command didn't work. The led didn't blink on and off for 3 seconds. I know this routine is good. Also, I shouldn't have to push a button twice to go from the if then statements of the password comparison to the menu_message, but it will just sit there until I press two buttons. I know that is no where in the code so I am confused as to why it is like that. Thanks for the help, and I am not uposed to learning. I do a couple of questions for you, in your code you wrote, you have this:

Lookup dtmf-"0",[%10101001,....... My question is what is -"0" for?

Also,

dtmf = 0:dtmf.0=DT0:dtmf.1=DT1:dtmf.2=DT2:dtmf.3=DT3
LookUp dtmf,["_1234567890*#"],dtmf how does the lookup table know which number has been decoded by using this sequence: dtmf.0=DT0:dtmf.1=DT1:dtmf.2=DT2:dtmf.3=DT3

I do a couple of questions for you, in your code you wrote, you have this:

Lookup dtmf-"0",[%10101001,....... My question is what is -"0" for?

It's a trick !?!

You have:
an ASCII-character (a digit "0"..."9") inside the variable "dtmf"

You want to get:
a bitpattern for the isd-chip.

Solution:
I used the lookup-command to index an bit-pattern. If I subtract the numerical äquivalent of "0" (IMHO 048 dezimal) from the ASCII-character in dtmf, I get an index-number 0..9. The lookup-command gets the bitpattern out of the list (10 patterns) and put it into the portC.

Also,

dtmf = 0:dtmf.0=DT0:dtmf.1=DT1:dtmf.2=DT2:dtmf.3=DT3
LookUp dtmf,["_1234567890*#"],dtmf how does the lookup table know which number has been decoded by using this sequence: dtmf.0=DT0:dtmf.1=DT1:dtmf.2=DT2:dtmf.3=DT3
Travin

Read it like:
Clear all bits in dtmf
Get the bit out out DT0 and put it into dtmf.0
Get the bit out out DT1 and put it into dtmf.1
Get the bit out out DT2 and put it into dtmf.2
Get the bit out out DT3 and put it into dtmf.3

So, the 4 bits are puzzled to the variable ! (index-number)
The lookup-command gets an ASCII-character for this number and stores it into the variable.

You love to work with ASCII-characters. It's not bad, but you have to convert sometimes from index-number to ASCII-character and back.

I assume here that when you say index number you mean a binary repesentation of that number. Does this make the pic run smother? By the way, I finally got your code to compile. It won't announce the digits as they decode not will it announce the array after the 8 digits are input. Still trying to make the program work like I need it to.

Thanks
