Yeah, yet another project in the works... Introducing something you waited for since a while...

OmniPlayerIII

Yup, a new rewriting of the famed web music player. Now on the features that distinguishes it from other players:

• Interface entierely in Javascript! (Now with more AJAX/JSON!)
• HTML5 audio!
• Winamp/WMP-like visualizations! (Coming soon!)
• Search by artist/album!
• Download links!
• Links to Facebook/Twitter/Bandcamp! (Coming soon!)
• Over 4 artists!
• Integration with Bandcamp! (Not sure if coming soon or not)
• Clouds! (Coming soon!)

Of course, you must have a fairly recent browser so it works. Please complain only if your browser is up to date. If you want your entire discography to appear there, feel free to PM me and I'll gladly add it! And if you have any idea or issue, feel free to reply on this thread and I'll see if it's possible.

And without further ado, here's the link!

Hi there! I need some help getting support for the TI-84+ Color Silver Edition in KnightOS. I started working on it a few weeks ago, and here's the current status of the color project:

• You can create KnightOS 8cu files and send them with BrandonW's UOSRECV tool
• Nearly all existing KnightOS features work
• The screen is not initialized correctly

Everything works great, except for the color LCD. I cannot get it to start up correctly. Here's what the color version of KnightOS looks like:



Note that the kernel works perfectly in KermM's jsTIfied emulator, which has poor emulation for the color LCD.

KnightOS Technical Background

For those of you unaware of how KnightOS is developed, here's some insight. The source code is hosted on and managed on GitHub, and is written mostly in z80 assembly. There are a number of git repositories:

• kernel, which is the core of KnightOS and does nothing on its own
  
• KnightOS is built on the kernel and provides the "KnightOS experience"
  
• CreateUpgrade creates and signs 8xu (and 73u and 8cu) upgrade files

There are more, but these ones are the ones that are important to KnightOS color support.

The relevant code

Color support is being worked on in the `color` git branch. The important code is this, which is meant to initialize the LCD:

; Destroys C
; A: Register
; HL: Value

    out (0x10), a \ out (0x10), a
    ld c, 0x11

This code is derived from a combination of reading wikiti, the LCD datasheet, and TIOS disassemblies. The code can be found in the display-color.asm file of the kernel repository.

How you can help

Want to help out? Here's how you can:

Download the latest version of the kernel with color support. If you're familiar with git and comfortable in a command line, use "git clone --recursive git://github.com/KnightSoft/KnightOS.git" and navigate to the kernel directory, then run "git checkout color".

Windows

Install cygwin and make sure you install GNU Make with it. Open up a cygwin terminal and navigate to where you have saved the kernel's source code. Run "make TI84pCSE" from that directory to create a kernel ROM. You can then create an 8cu upgrade file by running "CreateUpgrade.exe TI84pCSE bin/kernel-TI84pCSE.rom 0F.key kernel.8cu 00".

Linux/Mac

Make sure you have the latest version of tilp. Install mono (Arch: yaourt -S mono, Debian/Ubuntu: apt-get install mono-complete, Fedora: yum install mono). Run make TI84pCSE from the source code's root folder. Build an 8xu upgrade file with "mono CreateUpgrade.exe TI84pCSE bin/kernel-TI84pCSE.rom 0A.key kernel.8xu 00".

Testing

Download BrandonW's UOSRECV tool and send it to your calculator. Run "Asm(prgmUOSRECV" and wait for it to prompt for an OS. Send the upgrade with TI-Connect or tilp. Note that tilp support for the 84+ CSE is poor, and it may not work correctly. It is suggested that you press reset once more after receving the OS, instead of just jumping straight into it from the boot code's OS receiving code.

After some basic system initialization, the color kernel jumps into a test loop. The LCD backlight should blink 10 times, then the calculator will wait for you to press the ON key. The backlight will blink another 10 times and you'll enter the debug loop. You can press different keys to test out different things:

• A: Backlight ON
• B: Backlight OFF
• C: Initialize the LCD (call colorLcdOn)
• D: Turn off the device

Pressing C should ideally initialize the LCD and set it to a solid RED color.

The code for the debug loop can be found at the bottom of boot.asm. Feel free to modify any part of the kernel to help figure out what's going on.

To re-install TIOS, hold down DEL and press the reset button on the back. You should now be able to send TIOS.

So, want to make a quick bitcoin and help get third party operating systems onto the 84+ CSE? Any questions can be directed at [email protected], and I'll be keeping an eye on the threads in each forum I see this posted in.

It's there at the bottom of every page and the right column is missing on the main page, what did thou do guys?

The tides of the St. Lawrence river are getting troubled by the annual infestation of blue lobsters, causing several side effects akin to the Poison Joke from the My Little Pony series: Juju's hair getting blue, blue_bear_94 speaking a previously unknown language and Sorunome having derpy eyes, among other things.

That is, it's been 12 years ago today DJ Omnimaga founded the Omnimaga team. To commemorate the event, join us on IRC (irc.efnet.org #omnimaga) or OmnomIRC (if you have access to it) for special animation throughout the day!

Happy 12th anniversary and long live Omnimaga!

EDIT: We had an Omnimaga Story, as in a bot on IRC spitting a line of story every 15 minutes. Here's the transcript, text by Juju and bot by Sorunome:

Well, I just finally got around installing the emulator and noticed you can do lots of cool stuff.

So there's Unicode support in the variable names and there's a nice unicode charmap, which is pretty cool.



I'll post other findings when I'll stumble upon tem.

I decided to try implementing a binary puzzle as well, but in php and ncurses and, to my amazement, I managed to do it under 75 lines of code. Paste this in a php file, uncomment the ncurses and gmp extentions in php.ini and run this in command line. Supports color, multiple grid sizes, multiple puzzles and all the conditions to win! Also optionally takes a puzzle set filename and puzzle number as argument.
