So I took a few minutes to split your code up and see what you have. I am surprised that you were able to compile it. I found a few typos that should have been "}" but were ")" It also has a lot of global variables and a bunch of "goto" which makes it more difficult for me to follow. I would need to spend a couple of hours figuring out what it is doing.
As for the header files, the information necessary to rebuild the header files is listed in your code.
It looks like the header files would only contain the references to the functions that are called in main.c and function.c. Since all the source files are there, you could quickly recreate the header files.

Good Morning Sir!

Actually Sir, we are not the ones who did it. We cant compile it because these header files: functions.h, myuart.h, GSM.h are missing.

Can you tell us sir which of those " )" are wrong so that we could replace it with " }"?

I hope that there is someone who could help about the header files because we dont know how to make it.

Anyway sir, Thanks for your time...

I will take a look and see what I can do.

Thank you Sir.

hi.. been so long that i've havent checked the thread.. been busy this past few days... so, how was your project? and BTW, where did you get your code? i think "#include sio.h" is the library of UART functions.. i have used this one several times...

Is your project similar to this?



I made it using Zilog Encore Z8F6421 and Nokia 3310 cellphone.
GSM modules are easier to interface because they use Hayes AT commands unlike FBUS protocol used on 3310 model cellphones.
