I have 3 bugs to report.
1/3
[FATAL]
Effect: Unrecoverable error occurs (RAM clear)
Occurs: replicate by doing this:
Make a locked program in RAM with a DCS7 header and this code
Code: For(A,0,1024
getKey->B
If B:1024->A
If not(B:End
If B!=0 and B!=22 and......:Goto 0A
If B=22:Goto 2F
.........
If A>=1024:Goto 0A
Run it with DCS7.2 and let the program exit with a Return command. Now exit to TI-OS and run the same program and press [ON] during the for( loop. Immediately after it displays "ERR:BREAK 1:Quit", the LCD enters test mode, the error message is glitched all over the screen, lines flicker and after about 5 seconds of this, it powers off and resets.

[Minor]
Sometimes [ON] breaking a program and quiting with HomeRun enabled, when you return to the home screen, button presses do nothing except for [2nd][OFF], and [ENTER]. [ENTER] will (most that I've seen) type "0" and then this bug is over. [2nd][Quit] also ends the bug.
3/3
[Major]
Sometimes, after ungrouping programs, they still don't show up in Doors CS. I think it may be due to backing up folders and restoring them.
A weird bug that I have found. In one of my projects, copying a line from one program into another program will cause my calculator to crash. Other times, It will dump random stuff into the program that I am copying from, and upon saving the program after removing it, random stuff get drawn to the 2nd quarter of the screen from the left. when the random stuff gets to the bottom of the screen, the screen (as one would expect) freaks out for about five seconds, and resets the ram. Other times, my calculator will become unresponsive, forcing me to push the reset button on the back.
I found a bug having to do with using the "Stop" command in any program at any time in these circumstances:
xLib/celtic III/DCS libraries enabled AND Homerun enabled
OS 2.43
DCS7.3 running(Runer112 version)
When you run a BASIC program in the TI-stock prgm menu, the calculator will crash and ram clear once you hit "Stop" in any program.
This only applies with all the libraries above enabled, not an individual library.
This also does not occur when the BASIC program is run from the DCS7 menu.
Hello there.
There's a common bug with the ON key that i'm pretty sure all DCS users already experienced at least once.
When the key was just released, it's quite often interpreted as pressed right after.
I believe that's basically the result of a bouncing behaviour.
I quite recently performed some deep tests to identify the bouncing duration on TI-8X models (monochrome screen), and it appears it's actually pretty huge.
So, if you're looking for a basic (but safe) debouncing algorithm, here is the one i came up with after my tests :
Code: ;keybdebounce
;DESCRIPTION
;Waits long enough for released keys to stop bouncing.
;Recommended right after a key state just went from pressed to released.
;OUT
;a = ?
;f = %???????0
;bc = $0000
;stack : 2 bytes (call included)
keybdebounce
ld bc,102
in a,($02)
rla
jr nc,keybdebounce_wait
in a,($20)
or a
jr z,keybdebounce_wait
ld c,255
keybdebounce_wait
ld a,(bc)
djnz keybdebounce_wait
dec c
jp nz,keybdebounce_wait
ret

I'm kind of new to calculators and am learning BASIC, and it's great, and DCS is good too. But sometimes it does weird things.
So I have an old black and white TI-84 Plus. And I installed Doors CS, it's great. I like lowercase mode, instant Goto when errors happen, 8 lines in the editor, and the function det(1,x), which turns numbers to strings. But, (this has happened twice), the day before it works normally, and then the next day I turn it on and then do some math or coding or gaming—and then it won't turn off! I press [2ND] [ON] and nothing happens, the 2nd icon appears in the homescreen and then kind of quickly fades out when I press on. That's not all, though. When I run a program (to see if [ON] still works) and hit [ON] to break, Doors's usual screen (Error #512 Basic Ex Err:BRK 1. Quit 2. Goto error) pops up, but then I hit 2 and the dialog stays on the homescreen, and the 2 appears over it. But that's not all. When I (puzzled) enter more math, the error dialog stays and moves up like an expression.
Anyway I just got rid of Doors CS and reinstalled it, and then it worked fine, but I want to know (scientifically) why???
PS since then something else happened, which is:
I decided to go into settings and make it run on startup. So I pressed [Y=] then options, then I navigated the mouse to "make run on startup." Then I pressed [ENTER]. The screen froze, a little bit of the DCS homescreen (bottom center program) "showed through," then it went blank, I pressed [ON], it deleted my RAM. This was sad.
One last thing (probably not a bug). When I am in DCS and hit [CLEAR] to go to the homescreen because I want to do some math or something, for a millisecond an error screen shows up before it quits. What's that about??
Anyway, all this is making me want to ask for a TI-84+ CE for my birthday (today!) to replace my old (I don't know, 10 years?) hand-me-down 84+.
If my problems are stupid, please be kind, thank you!
