Re: Hardware vs software interrupt vectors

You can connect the phone to a serial port (UART) and talk to it with AT
commands.

Google is your friend here.

Hi Ruben,
                  Thanks for your reposne.
 
I never used AT commands in the HC 12 compiler. I wonder if I can use AT commands in C program. Would you know any website or book which can help me enhance my knowledge on At commands and help me use it with HC 12.
 
I am searching in google and trying to learn more about AT commands.
 
Thanks!

Hi, Mahesh

Use AT commands is not a compiler problem.
The soft problem is to be able to transmit (and maybe to receive) on a
serial port.

If you use CodeWarrior, you can ask the compiler to do that, but I can't say
anymore, because I don't use it (too expensive).

In other case, you have to write your own serial port driver, that means
write "putchar" function depending on what serial port you use...
When you have done this, you just have to send commands to your putchar or
puts function.
I've posted a couple of months (years ?) ago a serial driver on this site.

So, for me, under ImageCraft ICC12, I wrote
- my own "putchar" function
- so, printf, puts automatically use MY putchar

I think in fact the main difficult is WHERE to connect the serial port
(Transmit, Receive, GND) to the cell phone, and to know the speed of the
transmission. The remaining is easy.

Hope this helps.
Joel
