nanogui: Thread: Input device for nanogui

Greg,

How can I write a device driver for nanogui?

I have a touch screen. It has a normal serial line connection, and can act
as one or two button mouse with apropriate software.

Is it more straightforward to made a gpm driver?

Bye,

Look at the nano/server/drivers directory.  There are a number of device drivers
there for the screen, mouse, and keyboard.  My naming scheme was to
use scr_xxx.c for screen, mou_xxx for mouse, and kbd_xxx for keyboard.
Alex didn't like the naming scheme and changed it, I don't know what he did.

The mou_gpm.c file is the gpm-based mouse driver.  I have written a bare-hardware
serial driver for MS and PC mice, which you can have if you want.

Otherwise, look at these files, and it should be quick to implement
a driver....

I would say go the GPM route, then you can use it with X11 too (or others
can). Also gpm is a relatively stable item. You know if GPM dies its probably
your fault, with nanogui directly you can never be sure it being new code

The problem with the GPM route is it requires a separate process, and requires
fifo's, something that isn't implemented on smaller operating systems, like elks...

server/mouse/common.c
server/mouse/dos.c
server/mouse/gpm.c

I've kept the 8+3 requirement for it to unpack cleanly on an old DOS
system, but used nicer names.

Another thing I'm working on is a new mouse driver which is basically a
much pruned version of the GII mouse driver. The code is much cleaner than
GPM, but it still supports all the different mouse types that GPM
supports. It uses a data table to "describe" the properties of different
mice, so it's easy to add a new type to it.
