Hi,
I have found microwindwos on the net and compiled it for a digital sat
settop box runing under linux.
Congratulations a fine piece of software!
So microwindows is currently my favorite choice for my "problem".
(other are e.g. qt-embedded). But I have some questions.
Background:
A German pay tv provider is using Nokia, Sagem and Philips settop (all
similar
or nearly equal techn. layout). Due to the "bad" original software, some
guys
have ported Linux to this box, so now it's possible to write own GUIs or
applications. The boxes are running on PowerPC and some Avia chips.
Screen display and (Key)Input is done via Framebuffer and Infrared
RemoteControl
device.
After some reconfig (and very small hacks) Microwindows run on the
settopbox.
(there are still problems: screen size wrong, no input device, etc.)
But to use this software I have some questions:
- Will there be support for AlphaBlending (alpha/transparent channel) on
hardwarebase? (Of course it would be hard to do a software alphablend on
a running tv picture in the background, when displaying menus ;-) )
(currently cmap.transparent is set to NULL in the framebuffer source).
- Settop boxes normally only have an infrared remote - no keyboard (even
if an ir keyboard is possible - but not standard for everyone);-)
Are there plans to support IR devices?
- Can microwindows be stripped of unused functions? (reason: only
7 MB of flash memory for the complete system (kernel, libs,
applications, data).
- I couldn't find any clear pointer on the API (only the architecture
docs)
Are there more detailed docs, on the microwindows API (not the NANO-X,
or
WinAPI) - or am I totally wrong here?
- Is there support for freetype (true type fonts)?
If there are any changes, I would like to include IR-RC support, but
alphablending
has to be supported also by the APIs.
I would appreciate any info/reply on these questions.
If I some of my questions are answered in the FAQ, please just give me a
hint
(maybe I have overseen the answer).
Please be so kind to reply to my private mailbox, too (I'm currently
not subscribed to the maillist).
And again: good piece of work ;-)
