Hello all,
I am writing a program that will print some forms to a serial ticket
printer. I want to use the program space version of printf to do
necessary interpolation in a template. I would be using a mega8
Thing is: I want to store the templates in flash and then use them, but
I wouldn't like to declare them in a source file, but use a "section" (I
think that's how it can be done). This would be the structure of my code
space:
first address: Bootloader
1k later: Application
starting at 7k: Templates
...so I can use a bootloader to change only the templates.
I don't want to declare them in .c files as PROGMEM variables and
arrays. I have seen somewhere that you can declare a section somewhere
(linker file?) and so the costants are copied to flash (no source code
compilation) I would then remember the address for the start of my
templates for using that in the C programs that read the template.
How can that be done? I have looked into AVR GCC and Introducion to GCC
documents, but I cannot find a way to declare the sections and put the
data in.
Hope someone can point me to docs or in the right direction.
Thanks,
Hugo
