News / Re: "Luna" is here and converts your .lua files into 3.0.2-compatible .tns files

For those of you who are on OS X and are having trouble building Luna, I found out why it won't build. In the Luna's readme, it states you need gcc >=4.5, but apple's gcc is gcc 4.2. Using MacPorts (or Homebrew, Fink), install gcc 4.7 (run "sudo port install gcc47"). Then open up Luna's Makefile with a text editor and change any instances of "gcc" to "/opt/local/bin/gcc-mp-4.7". Cd to the Luna directory in Terminal, and do make "dist luna", and it builds!

Code: [Select]
CC:=/opt/local/bin/gcc-mp-4.7 CFLAGS:=-W -Wall -m32 LDFLAGS:= -lssl -lz -m32 VPATH := minizip-1.1 OS ?= `uname -s` ifeq ($(OS),Windows_NT) EXEEXT = .exe else CFLAGS := $(CFLAGS) -DUSE_FILE32API LDFLAGS:= $(LDFLAGS) -lcrypto endif all: luna$(EXEEXT) luna$(EXEEXT): luna.o zip.o ioapi.o /opt/local/bin/gcc-mp-4.7 -o $@ $^ $(LDFLAGS) dist: clean all mkdir -p dist/src rm -f *.o find . -maxdepth 1 ! -name 'luna$(EXEEXT)' -a ! -name dist -a ! -name . -exec cp -r {} dist/src \; cp luna$(EXEEXT) *.dll *.txt dist clean: rm -rf *.o luna$(EXEEXT) dist
Also, link for those who don't want to build themselves:

Thanks for sharing, I'm sure this will help several members

Where did you see that it has less memory? On the page it says 128MB flash and 32MB RAM (is that less than a CX?).

The CX has 64MiB of RAM.

General Calculator Help / Re: Hacking the TI Nspire CX Native OS?

« on: January 18, 2013, 03:56:08 am »

The best way is to hot patch the OS, add hooks and stuff such as Adriweb mentioned. This is probably more easy too.

It was 99 euro, so kinda cheap in comparison ^.^

TI-Nspire / Re: subnett and/or networking calc for nspire

« on: January 05, 2013, 06:03:31 pm »

Hi bearscup, there isn't such a calculator at the moment. However it shouldn't be too hard to make one^^
Maybe when I got a spare moment I'll make one.

I just finished my C.C.N.A. a couple of weeks ago, hope yours goes well too

Lua / Re: Question on TI-Lua programming

« on: December 31, 2012, 07:10:27 am »

Yes, indeed.

When just loading the script, the height and width of it are still 0, because the window is still loading. On your computer the window is already loaded.
The best is to use on.resize to set your width and height, as it will get called as soon as the window has a proper size.

Also, don't use image.copy in on.paint. The window doesn't resize every time you redraw it ^^
Rather do something like this:

Code: [Select]

str = "4\002\000\000t\001\000\000\000\000\000\000h\004\000\000\016\000\001\000\254\251\\159\239\159\239\159\ ... "

function on.construction()
    monImage = image.new(str)
end

function on.resize(width, height)
    h = heighy
    w = width
    px = w/2
    py = h/2
    wim = w/2
    him = h/2
    monImage = image.copy(monImage, wim, him)
end


function on.arrowKey(key)
    if key == "up" then
        wim = 1.1*wim
        him = 1.1*him
    elseif key == "down" then
        wim = 0.9*wim
        him = 0.9*him
    end

    platform.window:invalidate()
end

function on.paint(gc)
    gc:drawImage(monImage, px - wim/2, py - him/2)
end

Lua / Re: Question on TI-Lua programming

« on: December 31, 2012, 06:58:49 am »

Well, it's not a beginners mistake, don't worry

I'm not yet going to explain what is happening, but could you add

Code: [Select]

function on.resize(ww, hh)
 w, h = ww, hh
end

See if that helps

I'll explain later ^^

Lua / Re: [Lua] math.atan2() problem

« on: December 29, 2012, 07:22:04 am »

Could you test if the parameters you give to atan2 are the same?
Maybe some other issue causes certain variables to be different. (such as putting calculation code in your paint function).
Also, can you test just a single atan2 statement, no other code? That way we can see if that function really is the issue.

It's the content of the filesystem, used by the OS (Nucleus).
It included many things such as language files.

TI-Nspire / Re: Breakout board for the TI nSpire

« on: December 14, 2012, 02:38:51 pm »

Quote from: DebboR on December 14, 2012, 02:27:54 pm

Hello,

I'm currently developing a cheap breakout board for the TI nSpire series. I am developping this because I don't like to solder directly to my nSpire. This breakout board will be converting the dock connector to a connector with 0.1 inch pitch (normal header size). All 26 pins will be connected to a main connector, with two seperate pin headers for easy connecting of the UART, 3.3V and ground.

I'm letting you know this because if I get the breakout board prototypes, I get 10 pieces. Is anyone intersted in buying such a breakout connector? The price will be around €7 or €8 + shipping. I'm not at home ATM, so I will be posting some pics of the digital PCB render tomorrow.

Hi DebboR,
I'm interested in getting one

Something like this is very handy when debugging.
Looking forward to the renders!
