users_hwaredef.h

[Leif Asbrink]

Hi all,

Linrad has explicit support for just a couple of hardwares.
When you add something else you might want to add your own
(w)users_hwaredriver.c and/or (w)users_hwaredef.h and complie
from source. There are prototype routines in users.c and users.h

In case you want to use a FunCube on 1296 MHz the default
frequency control window would show 296 rather than 1296
because only 3 digits are reserved for MHz.

In hwaredef.h there is this define:
#define FREQ_MHZ_DIGITS 3

You can change it from 3 to 4, but you can also add a
users_hwaredef.h where you set the same define to 4.

(You might want to change other things also.)

There is a prototype routine users.h which you can rename
and place your own defines in. It is possible to write
direct support for FunCube or whatever in (w)users_hwaredriver.c
(prototypes in users.c)

The users* files (or wusers* files for Windows) can be copied from
one Linrad version to another to give the desired changes.

Then compile Linrad from source.

PS. Recent Linrad versions have an error in users.h:
#define FG_VSIZ (2*text_height+5)
This define should be:
#define FG_VSIZ (3*text_height)
which is what you would find in hwaredef.h DS.
