I don't have a problem doing that, however, I suspect very few people will find it
useful.
First, most people who understand how to use the code, won't have a use for it.
(don't need to talk to RCXs with standard firmware)
Second, most people who have a use for the code, won't know what to do with it (like
you)
In order to do what I wanted, I wrote a BrickOS program to send the "Get Battery
Power" command (0x30). Then, I had to modify the BrickOS kernal (firmware) to
process the Op Code returned from the standard firmware (0x38). bla bla bla.
To use my code, here's what you'll need:
1) The ability to rebuild the BrickOS kernal. If you downloaded BrickOS from the
web, you should be set.
2) my lnp.c file to include in #1
3) the "send command" program
4) An RCX to download BrickOS to
5) Another RCX with standard firmware.
If anyone out there has #1 & #5, I'll gladly provide my hacked up code.
Actually, I was thinking about writing the send program into the kernal. Then, I
could just post firmware that can be downloaded (via normal firmware download
techniques) to an RCX.
How about that?
Steve
