Post by thread:Final call for help.

Hi all, You probably would remeber that...from time to time i have been asking for your help (for my talking clock project) unfortunately, with out any success... probably i am asking too much! well i am ging to ask the ? again in the hope that some body some where might turn up with the solution. Can any one of you help with my project. I need some code for the pic or any alternative idea is wellcome by me any one willing to help please email me at spam_OUTshaileTakeThisOuTessex.ac.uk Thanks for your help S+

Hi. Your request is a bit too large for anyone to cover, other than to point you towards other sources on the web, which you could find through your own research. It's a bit like saying "how would I start designing a car?" or "anybody know why my car doesn't work?". Where would someone begin? If you you have a specific query, you might get more response. E.g. "Anybody know if a car diesel engine can be run off agricultural grade diesel fuel" or "anybody know why I get strange knocking noises with certain grades of fuel?". If you ask how to do entire projects, people will feel you are asking them to do your R&D for you.

Hi Thanks for the reply. well there is a special chip by ISD it is called ISD chipcorder you probably know this already. the Isd chipcorder can happly record any speech in analog format so the problem of a/d and d/a conversion is gone. what i need is a pic wizard to program a pic for me :-) so that it can capture the clock data from external clock module and map this information to the recorded speech on the ISD chipcorder. Do you think a pic can do this? S+ On Thu, 12 Feb 1998, D.

I think the second way is the easier one (don't need to > sample, A/D, D/A-conversion...).

Hi well my last email sound like I have no idea where to start..that is not true really. I have already recorded the neccessary speech using ISD chipcorder and already build a digital clock what I need is a pic wizard to program a pic for me :-) so that it can capture the clock data from external clock module and map this information to the recorded speech on the ISD chipcorder. how about that...still too much? {Quote hidden}> Hi. > > Your request is a bit too large for anyone to cover, other than to point > you towards other sources on the web, which you could find through your > own research.

Think divide and conquer. You've got to do two main tasks. One is to read the clock which you have not described so it is next to impossible to tell exactly what needs to be done, there, but you must read the clock and be able to use the digits you got as pointers to various addresses in the memory of the sound chip. I haven't yet built anything like this so I can't be any more specific, but that is the thought process that one needs to at least start solving the problem. If I were doing this project, I would concern myself with controlling the voice chip first. Look at the number of pins you will need and the protocol to address the chip and then go from there. The PIC, itself, can be your clock and voice chip controller since it doesn't take but a few counters to behave like a digital clock. I would want to use an interrupt to serve as master tick generator for this clock and then use the counter values to access the words you have programmed in to the voice chip. The tasks you must do and the number of pins you need for doing them will dictate which PIC and which strategy works best for your particular situation. That is what this game is all about and why it is fun. If you break the task in to several smaller ones and concentrate on just that part, you stand a good chance of ending up with what you wanted. As you run in to trouble with each of the small tasks, there are probably scores on this list who have already been there and done that but you need to supply most of the gray matter power to bring all these small building blocks together at the end. For some of us, that's the only way we get anything done. Martin McCormick WB5AGZ Stillwater, OK 36.7N97.4W OSU Center for Computing and Information Services Data Communications Group
