Recently, I've been having an upsurge in conlanging, so I'd like to share my constructed language with you: VE¹ENCS I'd also like to see your interests in constructing languages, if any.

2	Calculator Community / TI 68K Projects / accel68k - a 68k Basic IDE for your 68k calculator	on: 05 May, 2013, 03:24:09
Announcing accel68k - Your Future IDE for TI-89 Basic The development will not be in full force until AP tests are over, but I'd like to give you a preview of what is happening: - This IDE will use custom editing routines to ensure that key delays don't vex you anymore! In fact, the whole editing is overhauled in order to give a streamlined editing experience! - It will also give a range of refactoring features, including Local consolidation. - It will be full screen and (hopefully) use the small font as well. - It will be a hybrid of TI-Basic and C. To be precise, the editor itself will be in C, and the frontend (file selection, switching) will be in TI-BASIC. - It will require lots of knowledge about the EStack and the VAT, so help is appreciated! This will be my most ambitious 68k project of all, and I will furnish you with screenshots when I get the visual interface functional. Edit Got the skelly code for the backend attached! Edit II New skelly code and key layout pic! Edit III Holy shoot! That scan was huge! Now it's only 40% size.

3	Calculator Community / TI-BASIC Language / Avoiding stress from writing TI-89 Basic	on: 05 May, 2013, 02:07:22
About 1.25 years ago, I received a TI-89 Titanium, but even now, I can't create large programs on it without being stressed out by repeatedly pressing keys; the variable manager is cumbersome to use as well. Do you have any tips for reducing this stress (maybe using an external editor would work, but all of the installers I tried failed; is there a solution for that?). I really want to finish my relatively undeveloped RPG. Thanks in advance!

Calculator Community / TI-BASIC Language / To compose a program that works both on 83+ Basic and 68k Basic

on: 19 March, 2013, 03:20:19

So the challenge is to compose a program that works both on 83+ Basic and 68k Basic, in similar fashions. The example below clears the screen and prints "Hello World!" (This is only the body):

Code: Select All | Copy To Clipboard

If sin(1)=.841470984808
ClrHome
CLRIO
Disp "Hello World!"

Edit: sin(1) is equal to .841470984808 on the 83/84+, due to it comparing only ten significant figures, but these two values are different on a CAS calc such as the TI-89. So if you have an 83/84+, the program runs ClrHome; otherwise, it runs ClrIO (the expression CLRIO is treated as the product of five variables on the 83+ but the ClrIO command on the 68k). The final line is identical for both models.

Calculator Community / Casio PRIZM Hacking Discussion / Linker error - Can't use stdlib.h or math.h functions!

on: 05 March, 2013, 00:37:33

When I try to use stdlib.h functions (regardless of whether I #include <stdlib.h> or not), I get linker errors like these:

Code: Select All | Copy To Clipboard

bullets.o: In function '_freeList': 
bullets.c:(.text+0x384): undefined reference to '_free' 
bullets.o: In function '_createNode': 
bullets.c:(.text+0x39c): undefined reference to '_malloc'

Same for math.h functions. I also have the fxcglib installed. Are these functions not implemented yet?

Thanks in advance!

Hello, I just found out from Netham that the hosting service I was using contained malicious ads. I'm searching for another service; do you have any suggestions? 1) The service should provide a decent amount of account and forum functionality. 2) The service should not be malicious. 3) The service should be free. I was thinking about using Zymic, though.

As you know, TI is keeping us from using any of their stuff (including the OSes!) on emulators not from TI. (http://www.omnimaga.org/index.php?topic=15796.0) I'm planning to protest against this injustice at my school. You can do the same. What do you think?

8	Calculator Community / Other Calculator Discussion and News / Forty-eight hours of programming!	on: 22 February, 2013, 03:22:07
Next week, I have school off (except for Monday). So while my little brother isn't home, I'll be programming from Feb. 27, 12:00 EST to Mar. 1, 1:00 EST with a one-hour break. If anyone has that period off and would like to program as well, then I'd like to hear about it. So, I would appreciate a few fresh ideas for programming. Please note that I will (probably) be writing everything in C for the 68k series.

I am holding a "Club Design 1" course on the UCCP website (http://uccp.ucoz.com/), but you do not need to be a member of the UCCP in order to apply. Basically, this course covers aspects of creating clubs, not just pertaining to the student in school, but in general. Anyone who would like to apply should post here.

Calculator Community / Calculator C Language / [68k] Function not working as expected

on: 26 December, 2012, 01:08:25

Whenever I call enableUndo for this program (from a menu), I get light gray vertical lines as on the image attached. I think I did everything right, so here is the excerpt I am having trouble with:

Code: Select All | Copy To Clipboard

typedef struct {
 void* prevl,*prevd;
 char canUndo:1,isUndone:1;
} UndoInfo;
void* allocBUB(void)
{
 void* buffer=NULL;
 if (!(buffer=calloc(LCD_SIZE,1)))
 {
  dlgError(DMA_ERROR,MEMALLOC_FAIL);
  return NULL;
 }
 return buffer;
}
int allocGBUB(void** lbuff,void** dbuff)
{
 if (!(*lbuff=allocBUB()))
 {
  return 0;
 }
 if (!(*dbuff=allocBUB()))
 {
  free(*lbuff);
  return 0;
 }
 return 1;
}
void enableUndo(UndoInfo* p) {
 GrayOff();
 SetIntVec(AUTO_INT_1,I1);
 SetIntVec(AUTO_INT_5,I5);
 //*v: this may be the cause of the gray bars
 p->canUndo=allocGBUB((void**)p,(void**)((char*)p+4));
 SetIntVec(AUTO_INT_1,DUMMY_HANDLER);
 SetIntVec(AUTO_INT_5,DUMMY_HANDLER);
 GrayOn();
}

I would appreciate any assistance given!

Calculator Community / Calculator C Language / [68k] Incorrect Cursor Drawing

on: 30 November, 2012, 23:13:53

I decided to start using the latest GCC4TI release, but my graphic editing program now has a cursor glitch! (screenshot attached, along with how it's supposed to look)
My source code is also attached.
My code to draw the cursor is as follows:

Code: Select All | Copy To Clipboard

void drawCursor(unsigned int x,unsigned int y) //Draws the cursor
{
 unsigned char cursorl[8] = {
  ~0x80,~0xC0,~0xA0,~0x90,~0xB8,~0xE0,~0x90,~0x08
 };
 unsigned char cursord[8] = {
  ~0x80,~0xC0,~0xE0,~0xF0,~0xF8,~0xE0,~0x90,~0x08
 };
 unsigned char cursorm[8] = {
  ~0x7F,~0x3F,~0x1F,~0x0F,~0x07,~0x1F,~0x6F,~0xF7
 };
 
 Sprite8(x,y,8,cursorm,GrayGetPlane(LIGHT_PLANE),SPRT_AND);
 Sprite8(x,y,8,cursorm,GrayGetPlane(DARK_PLANE),SPRT_AND);
 Sprite8(x,y,8,cursorl,GrayGetPlane(LIGHT_PLANE),SPRT_OR);
 Sprite8(x,y,8,cursord,GrayGetPlane(DARK_PLANE),SPRT_OR);
}

This code worked as intended on TIGCC 0.96 Beta 8, but shows the wrong cursor on GCC4TI 0.96 Beta 10. Any help would be appreciated!

12	Calculator Community / Calculator C Language / [68k] GCC4TI makes .z89 file?!!	on: 29 August, 2012, 00:12:44
I was writing a program but for some reason GCC4TI (0.96 Beta 10) now making files with reversed extensions (.z89, .z9x, .zv2). The glitch is with only this specific project.

Calculator Community / Calculator C Language / [68k] Flood Fill

I was trying to implement flood filling with the right-hand algorithm (http://en.wikipedia.org/wiki/Flood_fill#Fixed_memory_method_.28right-hand_fill_method.29), but it don't seem to work. Here's the code specific to the flood filling:

Right now the contents on my screen is cut off to the right. I am using 2048x1152, the recommended resolution for the monitor, and I don't know how to fix it. Any ideas?

15	Calculator Community / Other Calc-Related Projects And Ideas / Calc Design	on: 09 July, 2012, 21:58:50
Over the last 2 nights I came up with a new calculator design. 1. The original keyboard layout and some specs. Notice the similarity to the TI-Nspire. Only with more programming capabilities. 2. Partial list of programming commands. HomeDisp is for the homescreen. 3. Improved keyboard layout. Note that the arrow keys should be larger. 4. Some "screenshots." Questions? Comments? Edit: I can't upload the images here; I'll post the links to them soon. Edit 2: The links are: 1 2 3 4
