Hi Waqar,

I was bored this morning, so I took a sudden interest in pulse dial decoding. Under the shower, I thought of what approach I would use. Enjoying 2 mugs of coffee, it took about 40 instructions in a timer interrupt, 22 byte variables, and 1,5 hours to write. So now I ACTUALLY have a file called pulsedial.asm, and it should be roughly 50% WORKING. Of course I don't have any hardware, so I can't test it, nor do I have the desire or the time to to get it up to 100%: My phone is working fine, and uses DTMF anyway.

Now the point is: I have some experience, but this is absurd. If it takes me, only an occasional embedded programmer, 1,5 hours on a lost saturday morning, why would it take you forever and a day to even get started? I could imagine that it would take you MORE time to do it, but not this long without a single sign of progress.

Meanwhile, you seem to use the time you should be spending thinking of whatever it was I thought of under the shower to create a lot of noise on this forum. You're not making friends this way. You seem to think you are pretty hard working, but I don't see any results. GET BUSY THINKING OF HOW TO DO IT IN STEAD OF BOTHERING EVERYONE ELSE, or finally face the fact that you are not cut out for this engineering shit and find another hobby.

Finally, I would suggest that you start looking for a SCHOOL. Internet forums are NOT NOT NOT going to make you an engineer. Really.

Cheers,

Hans van Pelt
