How do I use calcnet for Axe?
« on: January 14, 2011, 02:35:39 pm »
Insofar as I can tell, using calcnet seems to be fairly simple - a certain amount of RAM is allocated for data, and there are about 4 commands I can use to send/recieve data.  However, I have no idea on the specifics, and the nature of the sending-of-data.
So out of curiosity...

1] Which area of RAM can I store data to?  (I think it's L1?)
2] How do I instruct my calculator to send/recieve data?
3] When sending data, how exactly does it work?  Does it take the contents of my buffer and update every other buffer to match mine, or what?
4] Is there a way to use Calcnet without having to require/bundle DoorsCS 7.1 with each program?
5] Could somebody provide a simple example of an Axe program using Calcnet?
6] How do I simulate linking two calculators in wabbitemu?
7] How is Calcnet spelled?  Is it 'calcnet', or 'CalcNet', or 'Calcnet', etc...

you dont have to have cn, using a simple 2.5mm jack cable with get( and send( is enough

Ah, well, pretty much what I expected.

Okay,
8] Do the send( and get( commands send/recieve data for an extended period of time, or for only a brief millisecond?
9] Is it feasible to send about 100 bytes of data using get( and send(?

I cannot help you with Axe, but I can help you with CALCnet.  If you wish to pick my brain, I'll try to remember to check this topic (someone on #cemetech on IRC alerted me to it), but it's very likely I'll forget, so I'd ask that if you would like to pursue CALCnet that you poke my on Cemetech.

Using CALCnet is actually very important for having 3+ player games. It basically works with every calculator having a 3-byte address. When you send data to someone else, you store the address first, then the packet contents, then the size of the packet contents, in that order. Once you do that, the interrupt routine will simply send the information byte by byte to the target's recieve buffer. Look up the CALCnet2.2 whitepaper on cemetech.net.

the time is:
send(byte,timeinticks)
so to send 100 bytes in str1, you could use
for(a,0,99)
send({str1+a},10)
end

get checks if there's a byte in the link port
for(b,0,99
get->{str1+b}
end

*Five byte address, but close enough.  The whitepaper (and an abbreviated HOWTO) are at the following pair of links, respectively:

Idea, I can edit the topic title to "Kerm, read this or I'll eat you (CALCnet question)" so it highlights you on IRC. ;D

j/k that would get annoying :P

One of your most powerful tools is "if"

I think I might learn Axe+CalcNet some of these days. Those links are useful!

I really need to learn assembly one of these days.
Thanks for the links, Kerm!

When full axiom support is available, It might be easy enough to just do the basic calcnet commands without DCS.  If you were doing an app or something, that might be best considering how big DCS is.

So out of curiosity...

1] Which area of RAM can I store data to?  (I think it's L1?)
2] How do I instruct my calculator to send/recieve data?
3] When sending data, how exactly does it work?  Does it take the contents of my buffer and update every other buffer to match mine, or what?
4] Is there a way to use Calcnet without having to require/bundle DoorsCS 7.1 with each program?
5] Could somebody provide a simple example of an Axe program using Calcnet?
6] How do I simulate linking two calculators in wabbitemu?
7] How is Calcnet spelled?  Is it 'calcnet', or 'CalcNet', or 'Calcnet', etc...
1) About the first 600 bytes of L1 are used by CALCnet2.2, so if you want to store data, you must store to the end of L1, to L3 (abandoning grayscale, L4 (abandoning archiving), or an appvar in user memory (this is actually what I do in Eitrix, which is being developed here).
2) Read the CALCnet whitepaper on cemetech.net. Sending basically is storing bytes in certain locations in a certain order. Recieving happens automatically, and you only have to check the recieve buffer, do what you want with it, and then clear it. The CALCnet interrupt takes care of the rest.
3) CALCnet uses point-to-point sending. Each calculator has a unique 3-byte address based on its serial number. When you send data, you store where you want it to go, and it will get there in less than a tenth of a second if everything is working right. You would store 0 to the address to send the message to everyone (this is how you would send your ID), and use AAAAAA to connect to a router that connects to the Internet.
4) Sadly, you do need DoorsCS, unless you can somewhow embed the libraries into your program. Someone with influence at Cemetech could convince Kerm to make a smaller version with some of the features removed (such as the BASIC libs).
6) I don't know about wabbitemu, but Tilem 0.992 (the emulator I use) supports libticables, which allows an instance of the emulator to set a virtual link cable for linking together two calculators. You can also use this to link with a real cable (except for TI-84 Plus Directlink) which you could modify or couple to link with more than one calculator (although I don't know how good that is for your computer).
7) The first time you use it, you write CALCnet2.2. Thereafter, you can write CALCnet.

CALCnet is essential when you are sending a lot of data or linking more than one calculator (through simply splicing link cables together). Other than that, you should use Axe's linking functionality.
