General Calculator Help / Re: TI 83 Plus Black screen
« on: December 25, 2012, 04:41:06 pm »
Hey guys, I just want to let you know my calc is OK.
After I tried all possible key combinations I just put the calc in the drawer and forgot about it.
Today I thought that I could try HW flashing of NAND (asking for a backup here) to see if that would help.
So I inserted fresh batteries, junk appeared on screen as before, "RAM cleared" message as before, but this time, after I pressed Clear button, it kept working!
My guess is that some friend in class did something that froze the calc while playing a game, and the batteries were low already, so it just couldn't reset completely or something, causing the junk on screen. Although I did try replacing batteries for the first time, looks like I really needed fresh ones, straight from the pack :P

No, I don't have the warranty. I got French version of TI-82 Stats last summer, sold it and bought TI-83 Plus for the same money, second hand.

I took it apart and removed all batteries. I'll check it out next week.

OK, from screen blinking/turning off I concluded that my calc is crazy.
* The contrast is suddenly much lower.
* Only button that makes the screen blink/turn off is the DEL key.
* If I insert the battery with no buttons pressed, DEL key turns off the screen after it's released. No other buttons will do it. When trying to flash OS in this mode, TiLP gives the "not connected/timeout" error.
* If I insert the battery with DEL button pressed, DEL keys turns off the screen after it's released. No other buttons will do it. When trying to flash OS in this mode, TiLP gives "error writing to device/device not functioning error" which happens much faster after clicking "Forward" button in OS flash window than the delayed timeout message.

This is the error when I boot in DEL+battery mode, screen black, and try to flash OS via TiLP2:

(tilp.exe:2288): ticables-WARNING **: usb_bulk_write (libusb0-dll:err [_usb_reap_async] reaping request failed, win error: A device attached to the system is not functioning.

And error message box:
Msg: error occured while writing to the device.

So blagus, when you did the battery + DEL, did you see the boot code "Waiting..." message? Because if you did, then you clearly have a hardware issue. The only thing you could do in this situation is what was suggested above which is to leave all 5 batteries out for a while.

As I said, that combination still gives me black screen. None of combinations give me anything but full black screen, or slowly contrast-increasing black screen.

It was only one random occurrence when I got normal display, and I can't get to it anymore.

I guess it's a hardware issue, but which one?

@thepenguin:
1) Still leaves me with black screen.
2) Doesn't work. Actually I can't test it properly since I can't turn off calc to turn it on by CLEAR+ON, only when inserting battery, but it doesn't change anything. MODE+battery also leaves me with black screen.

@aeTIos:
So what's the solution?

As I said, once, while testing all random combinations, it actually displayed "RAM cleared" but it quickly returned to black screen.

I tried mem clear, and full clear too, 2nd, 7, etc.

@aeTIos: A friend was playing Sokoban. I don't know, given the technical knowledge of my friends, maybe they put something in archive, run Garbage collect which showed up once before, or something else that would screw up RAM/archive... but that should be reset by removing battery/holding CLEAR, isn't it?

@Hayleia: It's black.

General Calculator Help / TI 83 Plus Black screen
« on: June 26, 2012, 11:07:43 am »
I have a big problem with TI-83 Plus. Suddenly it got black screen without any special reason. I thought the low-contrast screen blinking was due to low batteries but I changed to new ones and it still displays black screen.
I tried everything, holding DEL, CLEAR, removing batteries, backup battery, setting contrast, flashing OS - it didn't work and TILP reports:
"Error writing to the device" and in console: "A device connected is not functioning"
I use Silver Link with properly installed drivers.

Then suddenly, it displayed some garbage for a second, then normal "Ram cleared" message, returned me to normal blinking cursor screen, but it quickly turned back to black screen.

I was googling a lot but I didn't find any solutions. All tips that worked for others don't work for me.
Also, unlike others, I'm not able to turn off my calc. It does react to DEL and ON button, also contrast gets lower when pressing 2nd key, but I can't turn it off.
What should I do?

TI Z80 / Connecting GSM modem
« on: March 31, 2012, 11:17:08 am »
I got an idea about connecting serial (RS-232) GSM modem to TI-83+ (and using it to send SMS, for example).
My guess is that it should be possible, since calc has serial interface (GND, Rx, Tx) and serial modem would be used (unless modem requires some more wires).
What do you say?

No, there's no TI.H at all in 83+ version of compiler.
But this one is different than 83 version I started with, and gives me different asm code.
Either C to ASM part is too buggy or I'm doing something wrong. This time I get no errors, but no other output either. Only sdcc command line.
Guess I'm too tired to set it up now... I'll try tomorrow, but maybe someone else wants to have fun with setting up too :)

Yes, I did it finally, and I get to this stage:
Code: [Select]
c:\tisdcc>tisdcc ti83p_asm hello.c
tisdcc
tisdcc: sdcc -mz80 --no-std-crt0 --code-loc 0x9DA3 --data-loc 0x9872 -L c:\tisdcc\lib -I c:\tisdcc\include -DTI83P -Wlc:\tisdcc\startup\ti83p_asm.o ti83p.lib hello.c
?ASlink-Error-<cannot open> : "c:\tisdcc\startup\ti83p_asm.rel"
Error in sdcc

hello.c:
Code: [Select]
#include "ti83p.h"
main()
{
PutS("Hello World!");
return 0;
}

Yes, I changed to puts and with minimizing code, I came to stage with no errors and successful assembly, and only error being fail to convert bin to "83p" since there's no app for that in the folder. So I do it manually (convert to 8xp).

And here's the TI-83+ C compiler, but for Mac: http://www.ticalc.org/archives/files/fileinfo/381/38118.html

Edit: I found Windows version! But I'm having some annoying problems with setting up path as readme says to do.

I'm not Nspire expert to tell you how to downgrade, but RS232 is standard serial port.

@ralph: I'm afraid you're right. I've minimized the code and still error.
Then I found the actual TI-83 Plus compiler, but it's made primarily for MacOS with badly compiled Windows executables.
I took ti83p.h from there and put it in 8x... compiler and still ERR:INVALID.

Still, it would be really nice if it could be modified somehow for TI-83 Plus.
