[Rcxemul-discussion] Progress

[David E. <d.a...@du...>]

Well, there hasn't been too much in the last few weeks. I'm officially
on vacation, so I'm attempting to spend time on boring things like
relaxation. ;)

However, I've got network comms sorted with the emulator. It will listen
on port 6561 (for now) and when it receives a datagram packet, it will
print it to the screen (along with the IP address of the originator). It
only checks every 250 iterations (I'm planning on working out a better
value for this - I've tested with 2500 and the messages still get
through) and uses the Unix select() function, so only blocks for a given
time (10ms in my case - it's about as low as it goes). Hopefully it
won't create too much of a performance hit.

The next thing to do is to create a virtual IR tower to act as a relay
between the firmware download application. I would like to do this
without modifying the download code in any way... This way I can assure
that any firmware can be downloaded.

However, I have no clue how to do this in C! I'm working with the cygwin
environment, so Unix rules apply. If anyone knows how I can do this, I
would appreciate any help I can get!

That's about it for now, apart from a consistent crash I'm getting when
stepping through code. I'm working on fixing that, but for the moment
I've disabled this feature. I also need to change the interrupt routines
so that only the high priority interrupts are accepted when in sleep
mode.

Dave.
