Title: Zeda's Hex Codes
Post by: Xeda112358 on January 29, 2011, 11:26:20 pm: Hey all you BASIC programmers out there (and occasional Axer)! I have something that YOU might like. You know those amazing little creatures? Those hex opcodes? Well guess what?! I've got em :D

Here is a small PDF that I have been working on that has a mild sample of about 40 hex opcodes. If anybody has cool suggestions, lemme know and I'll see what I can conjure up!
Title: Re: Zeda's Hex Codes
Post by: Deep Toaster on January 29, 2011, 11:29:53 pm: Whoa, that sure beats http://tibasicdev.wikidot.com/hexcodes :w00t:

Awesome work, as always. You should update that page too ^
Title: Re: Zeda's Hex Codes
Post by: Xeda112358 on January 29, 2011, 11:36:18 pm: I have been :D I optimised a few codes on that page and you will see my posts littered all over TIBD with random hex codes :D
Title: Re: Zeda's Hex Codes
Post by: ztrumpet on January 29, 2011, 11:43:02 pm: There are some of Zeda's (aka Thunderbolt) Hex Codes already there. :) Nice pdf. ;D
Title: Re: Zeda's Hex Codes
Post by: Xeda112358 on January 29, 2011, 11:48:33 pm: Thankee! Yeah, I now have that document uploaded on UTI, TIBD, TICalc, and here. Whenever somebody asks for an opcode, I plan to add it to that document. I still need to add CopyProg...

Title: Re: Zeda's Hex Codes
Post by: Xeda112358 on January 30, 2011, 09:26:01 pm: Yeah, I know what you mean :D That's why I'm doing this. I've really gotta find some new ideas for opcodes, though. I mean, I have tons of opcodes, but some of them get really involved.
Title: Re: Zeda's Hex Codes
Post by: DJ Omnimaga on January 31, 2011, 12:53:23 am: Cool! Nice job! Should you put them on WikiTI too? I think they got a page with hex opcodes for BASIC programmers.
Title: Re: Zeda's Hex Codes
Post by: Xeda112358 on January 31, 2011, 12:56:58 am: Oh, how do I put them there?
Title: Re: Zeda's Hex Codes
Post by: DJ Omnimaga on January 31, 2011, 03:26:20 am: Oh for that you would need to register and edit the page there. You would need to learn Wikimedia syntax, though.
Title: Re: Zeda's Hex Codes
Post by: mrmprog on February 14, 2011, 09:54:07 pm: Any new updates on these opcodes?
Title: Re: Zeda's Hex Codes
Post by: program4 on February 14, 2011, 10:05:38 pm: Perhaps the ASM equivalents of certain drawing commands would be good, like PxlOn( and PxlOff( and Line(. Sometimes drawing on the graphscreen is slow...

Also, are you going to put in the number to string hex opcode? Somehow I am obsessed about converting from a number to a string. :D
Title: Re: Zeda's Hex Codes
Post by: Xeda112358 on February 14, 2011, 10:07:32 pm: Well howdy *cough* stranger *cough*. Hmm, well I do have a few opcodes now that you mention it... Also, do you have any new ideas?

This is pretty much the opcode of CopyProg:
Code: [Select]
EFD74AFE04C013131AFE712837 3EAA327984D7D878B7C0 EB4E234623C5 7EE61F77 117884 EDB0 AF12 EFF14278C1D8 EBD306 B728050901090009 4E234623 F5E5C5 3E07D306 EFD74AFE04 EB4E234623 7E FE71F52003237E0D E61F77 117884EDB0AF12 EFF1423803EFC64F F1C8 E1E53A7884 EF704E1313 C1E1F1 EF5480 C9You will probably need to read what that one does either in the CopyProg topic here or on UTI or on TICalc, but it really is a very useful program...

Input a list and it outputs ASCII on the homescreen:
Code: [Select]
EFD74A3DC0 EB462323 C5EF7A41E5 EFEF4A EF0445 E1C1 10F1 C9An example for this one would be using 65+{7,4,11,11,14:Asm(prgmDISP. That will display HELLO on the homesreen. The cool part is that if you change the 65 to 97, it will display the lowercase version :D

I would prefer to keep the codes a little on the smaller side, so if y'all have any random ideas, please feel free to ask!

Title: Re: Zeda's Hex Codes
Post by: Xeda112358 on February 15, 2011, 11:58:10 am: Okay, this code returns the iPart( value of a real number as a string. So if you do -334.67:Asm(prgmR2S, Ans will be the string "-334"

Code: [Select]

Um, that's the Int command. The iPart( command returns the imaginary component of a complex number.

I thought iPart( returns the integer part of a number?
Title: Re: Zeda's Hex Codes

Title: Re: Zeda's Hex Codes
Post by: DJ Omnimaga on February 23, 2011, 05:00:41 pm: Yeah, I think the difference between int and ipart was with negative numbers or something. You would have to check TIBD for the differences.
Title: Re: Zeda's Hex Codes
Post by: program4 on February 23, 2011, 05:46:31 pm: iPart just takes off anything to the right of the decimal, so iPart(-1.7)=-1. int is the greatest integer function, or the greatest integer less than the input. Since -2 is the greatest integer less than -1.5, int(-1.5)=-2.

Oh, sorry, I never saw this post... erm, the latest updated version... is included in this post! :D I only added a few codes and programs, but here is version 1.20

EDIT: I accidentally put another opcode for RunIndicator Off. I put EF0745 which is something I use very frequently (for debugging) instead of EF7045.

Title: Re: Zeda's Hex Codes
Post by: squidgetx on February 26, 2011, 11:44:03 am: Xeda, is the Off code the equivalent of actually turning it off, in terms of power consumption?
Title: Re: Zeda's Hex Codes
Post by: Deep Toaster on February 26, 2011, 11:49:46 am: "Calc off" turns off the LCD only, I believe. Then there's bcall(_powerOff), which is EF0850, but that doesn't even completely power off the calculator.
Title: Re: Zeda's Hex Codes
Post by: Xeda112358 on February 26, 2011, 12:20:39 pm: The ones that turn the screen off is immediately following. The one I provided does turn off the calc without using the bcall. (it modifies the Status port)
Title: Re: Zeda's Hex Codes
Post by: Xeda112358 on February 27, 2011, 10:43:19 am: Okay, so if you read the edit to the previous download, I accidentally the run indicator off opcode, so here is a fixed version. I use EF0745 much much more frequently (for debugging) than EF7045 so.... oops? It doesn't harm anything, it just displays a number that I use in debugging to check register values. Luckily, somebody over on TIBD mentioned that the library they were working on kept displaying some random number instead so... Thanks BlakPilar!

Post by: Xeda112358 on February 27, 2011, 12:40:43 pm: Which one? Or do you mean all of them >_> ? :D if you have any ideas, too, feel free to let me know!
Title: Re: Zeda's Hex Codes
Post by: Deep Toaster on February 27, 2011, 02:15:39 pm: This might be hard, but how about writing back a string to a label in the program? Something like

Code: (TI-BASIC) [Select]
:Lbl 0 :{1,1,2,3 :Lbl 1 :Ans→L₁ :"{1,3,4,7→Str1 :"0,1 :Asm(SMC
True SMC in BASIC is something we have yet to see :D
Title: Re: Zeda's Hex Codes
Post by: Xeda112358 on February 27, 2011, 02:21:57 pm: You mean like have it overwrite the data following Lbl 0? Hehe, if that is what you mean then you can do something like that with CopyProg because you can store the program as a string and manipulate it and you can use CopyProg to execute the string as a program :D

CopyProg was originally requested as an opcode by mrmprog, so I decided to include it in the list of opcodes :D

However, if you mean edit a line of code following Lbl 0 and to be able to edit it inline like that (while the program is executing), that could be fun... I might need to adjust a few pointers to make it possible, but it can be done, I believe.
Title: Re: Zeda's Hex Codes
Post by: ztrumpet on February 27, 2011, 03:31:23 pm: Actually, Iambian wrote a small program called Celtic to do this a few years back. It kinda evolved since then...

Post by: Xeda112358 on February 27, 2011, 03:34:29 pm: Uh-huh, I remember something about that, I cannot remember... what did he call it again, Gaelic? ;D
I still think an opcode would be nice for those who don't have connectivity stuff to download :)
Title: Re: Zeda's Hex Codes
Post by: DJ Omnimaga on February 28, 2011, 03:33:11 am: If you really mean Celtic, it's still called Celtic today, but since it stopped being updated, it has since merged with Doors CS 7.
Title: Re: Zeda's Hex Codes
Post by: program4 on March 01, 2011, 09:00:08 pm: I have an idea: how about a program that allows detection of multiple key presses (like the one in BatLib, I think)? I might find that useful in some BASIC programs.
Title: Re: Zeda's Hex Codes
Post by: mrmprog on March 01, 2011, 09:04:30 pm: That would be handy, and so would an inline editor.What about a find and replece routine where you could search for str1 in a var and replace it with str2? You can do that with copyprog but an opcode would be faster.

Hmm, as a quick reference to that, you can check here (http://www.ticalc.org/archives/files/fileinfo/425/42546.html) for two versions of what you might be looking for. returns all of the keys being pressed in the form of a 7 element list. This is command 10 (pretty much) in BatLib.

A better option might be this (http://www.ticalc.org/archives/files/fileinfo/432/43208.html) might be more practical/useful as it doesn't require an input. This is command 43 in BatLib.

A code to change token vars (not programs/appvars or other named vars) is actually not too difficult. I will come up with one shortly and edit this post when I have it finished!

EDIT: Actually, see my next post for the code :D

Post by: Xeda112358 on March 02, 2011, 12:26:05 pm: It isn't the opcodes that break when you press ON, it breaks when the program finishes and enters BASIC again :D
Anywho, instead of editing my previous post, here is an opcode:
Code: [Select]
EFD74AFE04C0 1313 21B184EB EDA0EDA0 3EAA327984D7D878B7C0 1313 21AF84EB EDA0EDA0 3C327A84D7D878B7C0 EB4E234623 117884 EDB0 AF12 EFF142D878B7C0 EB4E234623 3AAF84 EDB1E0 3AB084 BE20F4 3AB284 772B 3AB184 7723EDA1E018E5The inputs are:
Str1=SearchStr
Ans=ReplaceStr
Str2=VarName

What it does is it takes the first two bytes of the search string and finds those in the variable you are searching. Every time it comes across a match, it replaces it with the first two bytes of the replace string.
*VarName uses the same syntax as CopyProg

So if I wanted to change every instance of Goto 0 to Goto V in prgmRAWRZ
Code: [Select]
"ERAWRZ→Str2 "Goto 0→Str1 "Goto V Asm(prgmREPLACESince tokens like Str1 and Pic1 are two bytes, you can similarly do something like:
Code: [Select]
"ERAWRZ→Str2 "Pic1→Str1 "Pic7 Asm(prgmREPLACEThe variables have to be in RAM in order to edit them, otherwise the code exits.
Title: Re: Zeda's Hex Codes
Post by: Deep Toaster on March 02, 2011, 06:26:03 pm: A find/replace function? :o These hex codes are getting to be really useful!
Title: Re: Zeda's Hex Codes
Post by: Xeda112358 on March 02, 2011, 06:29:28 pm: It only uses two bytes, though, but I have been meaning to get around to making an actual search/replace function for BatLib, so when I do, I will post the code :D

EDIT:I just thought of an interesting use for this program !
Code: [Select]
1→B ClrHome Disp " Goto 1"," Goto 2"," Goto 3 ;Put a space before the numbers :P Repeat A=105 Output(B,1,"} Repeat A getKey→A End Output(B,1," ;There is a space there B+(A=34)-(A=25 If Ans=4 or not(Ans 1+2not(Ans Ans→B End "EB1→Str2 "Goto A→Str1 "Goto "+sub("123",B,1 Asm(prgmB Goto A Lbl 1 1 Goto Z Lbl 2 2 Goto Z Lbl 3 3 Lbl Z Pause AnsYou can potentially avoid using the Menu( command to jump to labels if you reallllly don't want to use the built in Menu( command :D
Title: Re: Zeda's Hex Codes
Post by: Xeda112358 on March 03, 2011, 02:30:26 pm: Here is a cool little opcode... it will take a string in Ans as the name of a var to execute as a BASIC program. The input is also the same as CopyProg (or the output of GetName). So for example, if appvar HELLO has BASIC data, you can do:
Code: [Select]
:"UHELLO :Asm(prgmEXECAnyway, the opcode is:
Code: [Select]

Storing to Ans is not a problem, just reading from it. If you want to store the Axe "Ans" to the OS Ans, you would need to do EF9247EF5641EFBF4A

To store to Ans and make use of numbers greater than 9999, then you would need a code that looks kind of like this:
Code: [Select]
7EE5E60FCB3FF53C4F060009EB606822B48423F130061AE60FCDB54E1AE6F007070707CDB54E1B0D79B720EAE111090019ED5BB4847BC9 D5E5CD804EED5BB4841922B484E13E0ACD804ED1C9 EB0608210000290730011910F9C9Do not use that because that only works in a very specific context, but that is what the code looks like in BatLib. I am not sure how to translate that to Axe because it uses calls.

Anywho, the OS bcall EFEF4A does not convert numbers >9999, but EF9247 can store numbers up to 65535.

ReadAns:
EFD74AEFEF4AEB
StoreAns:
EF9247EF5641EFBF4A

If you want to use this in Axe and you want to preserve Ans, simply put an E5 at the beginning and E1 at the end.

Yes that's exactly what I mean. I'm still messing around in BASIC so that would be a very fast way to do sprites.

It has the opcode included :D

FreeRAM stored to Axe "Ans" is this: 2A1598, I believe. If that fails, just do EFE542
Title: Re: Zeda's Hex Codes
Post by: Xeda112358 on March 26, 2011, 10:28:47 am: Okay, so I have 5 more opcodes, 3 simple ones and 2 less simple:
These simple ones I found in an "Extra.txt" document included with one of my old programs :D I seem to keep things like this in scattered places :)
Auto DMS
21FA893E0677C9
This displays any number in Degrees-Minutes-Seconds automatically.

Auto Fractions
21FA893E0C77C9
This displays numbers in fraction form if they can be, automatically.

Remove Cursor
FDCB0CE6C9
This stops displaying the blinking cursor.
CharLength
This one is one I added to BatLib a little while ago. It returns the char length of a string instead of the token length. For example, where length("sin(ln( would return 2 in BASIC, this code returns 7 because there are 7 chars.
Code: [Select]
EFD74AD604C0 676FEB 4E234623EB C5D5E51A EFA342F5 EBEF9445 F1E1D109C1 20020B13 0B1378B120E5 EF9247 EF5641 EFBF4A C9SCharLength
This returns the pixel width that a string would use if displayed with the small font.
This one was a request from earlier this morning:

EDIT 2: I forgot to change some 7E's to 1A's when I was optimising my BatLib version... The last two have been adjusted accordingly.

Title: Re: Zeda's Hex Codes
Post by: Xeda112358 on March 26, 2011, 08:01:08 pm: From an offset? Or that bit? Since you cannot actually edit Flash, here is a version that has its offset in RAM:
The code starts the same way, so you can make this a call (I am assuming you are using Axe):
Code: [Select]
7DE6073C473E010F10FDCB2CCB1DCB2CCB1DCB2CCB1D01008009Using the following codes, you can add them to the end of the above code or if you are using a call you use it after the call:
Code: [Select]
BitOn: B677 BitOff: 2FA677 BitChange:AE77 BitTest: A63D3FED6223If instead you want to perform BitOn, BitOff, and BitChange and return the previous state of the bit, use these:
Code: [Select]
BitOn: 47A63D3FF578B677F1ED6223 BitOff: 47A63D3FF5782FA677F1ED6223 BitChange:47A63D3FF578AE77F1ED6223So here is a code to turn on a pixel and return HL as 1 if the pixel was already on or 0 if the pixel was off using Axe code (to make it more clear):
Code: [Select]
Asm(7DE6073C473E010F10FDCB2CCB1DCB2CCB1DCB2CCB1D01008009 Asm(47A63D3FF578B677F1ED6223

Title: Re: Zeda's Hex Codes
Post by: Xeda112358 on March 27, 2011, 01:11:29 am: So you couldn't use pixel on/off or are you editing sprites directly in a data file?
Title: Re: Zeda's Hex Codes
Post by: Freyaday on March 27, 2011, 01:18:18 am: This is to create the sprite data, because currently the sprite only exists in the graph screen buffers.
PS: I have a Great Aunt Zeda. She has a road named after her.

Edit: Will this work on the last 8 pages or will it overflow and screw me over?

^-^

EDIT: Oh, wow, I never saw your edit Freyaday... I am not sure what you mean, but using the example before of turning a bit on and returning the previous state, this version also uses two pointers-- one points to the data, and the other is the bit offset:
Code: [Select]
<<Ans points to a var>> Asm(E5 <<Ans is the bit to edit>> Asm(7DE6073C473E010F10FDCB2CCB1DCB2CCB1DCB2CCB1DC109 Asm(47A63D3FF578B677F1ED6223

I hope you do.

Is this group of hex codes the right place for me to add routines like this (http://wikiti.brandonw.net/index.php?title=Z80_Routines:Math:Multiplication) in hex? Or not really?
Title: Re: Zeda's Hex Codes
Post by: Xeda112358 on April 21, 2011, 11:39:20 am: Er, not really :/ These are tools for BASIC programmers, not routines for assembly programmers :)

Yeah I thought so, I need to create some library like that, but then again, not that useful.
Title: Re: Zeda's Hex Codes
Post by: Xeda112358 on September 03, 2011, 06:18:11 pm: I was on the french site tout82 trying to help out with some hex codes for the 82/83 when I thought of an optimisation that applied to about ten of the codes. Here is an example:
Code: [Select]
Auto Fractions: 21FA893E0C77C9 optimises to: 3E0CFD770AC9
Code: [Select]
Alpha Press Lock 21028A3ED0B677C9 optimises to: 3ED1FD7712C9
So here is v1.31
Title: Re: Zeda's Hex Codes
Post by: Xeda112358 on March 12, 2012, 02:40:42 pm: Yay, a necropostable topic! I cannot believe I never added these two codes, these are codes I am proud of for making!

Shift screen right 4   (Added v1.32)
2140930E40AF060CED672310FB0D20F5C9
This will shift the screen right 4 pixels.
Shift screen left 4   (added v1.32)
213F960E40AF060CED6F2B10FB0D20F5C9
This will shift the screen 4 pixel left.

Also, for completeness:

Shift screen up 4   (added v1.32)
21709311409301D002EDB0EB013000EF304CC9
This will shift the screen 1 pixel up.

Shift screen down 4   (added v1.32)
210F96113F9601D002EDB823013000EF304CC9
This will shift the screen 1 pixel down.

I wonder what else I should add...
Title: Re: Zeda's Hex Codes
Post by: Xeda112358 on November 27, 2012, 08:24:37 am: In a future update, I should include:
Edit Lock/Unlock Programs
EFD74AFE04C03CEB4E234623117884121CEDB0AF12EFF142D8EE0377C9

Put the name of the program in Ans, if it exists, this will toggle the lock status of the program. Maybe I should also make a Hide/Unhide code and a short code to toggle between appvars and programs. These two, however, would require that I check for duplicates, so the code would get even more involved.

EDIT:

This might be hard, but how about writing back a string to a label in the program? Something like

Code: (TI-BASIC) [Select]
:Lbl 0 :{1,1,2,3 :Lbl 1 :Ans?L? :"{1,3,4,7?Str1 :"0,1 :Asm(SMC
True SMC in BASIC is something we have yet to see :D
Almost two years ago, but... I do not have the opcode for this one since the programs (http://ourl.ca/17635) are pretty big, opcode-wise, but I finally made it :D I think it is rather snazzy as well. Also, I am not content with this being the final version :P When I do finalise it, I will put it in the hex opcodes list.

EDIT2: This is more for Axe programmers. I looked back at this post and felt that I should update it. I created a much better routine for Grammer and BatLib that I have adapted for Axe. It is now much faster and it works with relative addresses. Also, it recognises negative numbers:
Quote from: Xeda112358 on March 04, 2011, 11:54:05 am
To store to Ans and make use of numbers greater than 9999, then you would need a code that looks kind of like this:
Code: [Select]
7EE5E60FCB3FF53C4F060009EB606822B48423F130061AE60FCDB54E1AE6F007070707CDB54E1B0D79B720EAE111090019ED5BB4847BC9 D5E5CD804EED5BB4841922B484E13E0ACD804ED1C9 EB0608210000290730011910F9C9Do not use that because that only works in a very specific context, but that is what the code looks like in BatLib. I am not sure how to translate that to Axe because it uses calls.

Anywho, the OS bcall EFEF4A does not convert numbers >9999, but EF9247 can store numbers up to 65535.
Blegh, such an inefficient code XD Anyways, these 70 bytes can go in Axe, in-line, using Asm(

Code: [Select]
EFD74A2178847EE680F5237ED68011000038284704237E07070707E5626B29291929EBE1E60F835F30011405280D3E80A8280847077E38E32318DBF128077B2F5F7A2F5713EBIt is a bit big, but it works. Plus, it can be easily adapted further to make it easy to read list elements, so if you want to pass a list to your Axe program (for a library, for example), you can.

Post by: Xeda112358 on January 09, 2013, 11:31:22 pm: Last night I posted a hex code on TI-BASICDeveloper for making programs run on startup. To use it, pass the name of the program in Ans with a "[" before the name. For example, to run prgmHELLO on startup:
"[HELLO]:Asm(prgmOFFSCRPT

Title: Re: Zeda's Hex Codes
Post by: Shmish21 on September 28, 2020, 01:21:21 pm: How would you make the I/O port set the ring and tip to high/low and stay there? (Tried to add in my own native assembly but it didn't work, also sorry for posting on a potentially dead Forum)
Title: Re: Zeda's Hex Codes
Post by: Xeda112358 on September 28, 2020, 02:14:23 pm: In binary, when you write 00 to port 0, it sets the two lines to 1 (HIGH maybe?). Basically, what you write gets inverted.
When you write a 0 to one of the lines, you kind of release it, but when you write a 1 (setting the line LOW?), you kind of lock it there.

So when you have two calculators connected, and one sets the lowest bit to LOW, the other calculator cannot pull it HIGH. But when the line is already HIGH, either or both calculators can bring it LOW.
When both calculators bring a line LOW, it remains LOW until all calculators have "released" it back to high.

A TI-OS-related caveat: at the home screen or in a BASIC program, if the lines are not released, the calc will basically be frozen, so before you return control back to TI-OS, make sure to write a 0 to port 0 (this brings both lines to 1).

Now, given the topic, I would assume that you want a hexcode. There are many ways to interact with the port, but the very basics: 3E0xD300, where x is 0, 1, 2, or 3 will write to the port, and DB00 will read from the port.

Thank you so much, your knowledge on this stuff is outstanding! Another quick question I have is what would each of the different statuses do exactly. I know you already explained what writing 00 and 01 do, but if possible could you put what each does 0-3. It would help to be able to reference back to it.

P.S. I am using the I/O port for 1 bit sound purposes.
Title: Re: Zeda's Hex Codes
Post by: Xeda112358 on September 28, 2020, 05:23:48 pm: The numbers in binary:
0 ==> 00
1 ==> 01
2 ==> 10
3 ==> 11

So writing a 3 brings both lines LOW, writing 2 sets the upper line LOW and the lower line HIGH.
Writing 0 and 1 do the opposite of 3 and 2, respectively.

The routine here (https://www.omnimaga.org/the-axe-parser-project/assembly-programmers-help-axe-optimize!/msg273787/#msg273787) might be useful to you :)
