Doors CSE 8.1.2 Brings Bugfixes, Compatibility
Published by KermMartian on December 4, 2014 at 8:50:02 PM CST | Discuss this article (6)
Doors CSE 8 is the first and currently only assembly shell for the TI-84 Plus C Silver Edition, TI's flagship color z80 calculator. Built on the Doors CS 7 codebase, it lets you run any kind of TI-BASIC or assembly program, run and edit archived programs, use extra functions in TI-BASIC programs, and offers myriad additional features to make the TI-84+CSE more powerful. The most recent big update to Doors CSE was Doors CSE 8.1 in July: it brought new Hybrid BASIC functions, the ability to list and run Applications, and many bugfixes. Doors CSE 8.1.1 was subsequently released in August, and now Doors CSE 8.1.2 is available. These new updates bring the following fixes:

Another month has ended, and December is upon us, which can only mean that the time has come for another Projects of the Month (POTM) article! As always, administrator tifreak8x has selected the most interesting and exciting projects created or updated on Cemetech in the past month for your enjoyment. Without further ado, here's what Cemetech's ingenious members have been working on this month:
We hope that you're hard at work on your Cemetech Contest #13: Games with Cats & Space contest entry, and we look forward to bringing you more exciting projects at the end of the year. Who knows; perhaps we'll decided to have a little Program of the Year (POTY) of our own...
ArTICam: Game Boy Camera Photos with a Graphing Calculator
Published by KermMartian on November 28, 2014 at 2:29:48 PM CST | Discuss this article (8)
For several years, the idea of video-chatting using graphing calculators and globalCALCnet has been jokingly tossed around on Cemetech. More realistically, ideas about connecting a Game Boy camera to a graphing calculator have been discussed here for at least three years; as early as 2004, the users of United-TI were discussing the feasibility of such a project. In February 2011, Cemetech administrator Merthsoft and I bought Game Boy cameras for such a project, but for over three years, my camera lay unused in my toolbox, disassembled but forgotten. Two weeks ago, a discussion during our weekly Have Calculator, Will Program (HCWP) teleconference led me to pull it out and seriously consider connecting the camera to a calculator.
The recently-published ArTICL Arduino-TI Calculator Linking library made this project quite straightforward by providing an easy way for an Arduino to talk to a calculator. The Game Boy camera requires six digital I/O lines and one analog line, so it could not be connected directly to a calculator, but an Arduino turned out to be a perfect platform to use for controlling the camera. In fact, existing code for interfacing the Game Boy camera's M64282FP image sensor and AVR microcontrollers already existed, and combining this with ArTICL turned out to be the work of a few days. With no additional hardware beyond an Arduino and a Game Boy camera, monochrome or color graphing calculators can now take and display photographs. In fact, because the Arduino pretends to be a calculator (or in some cases a CBL2 device), absolutely no extra software is required on the calculator. To take a picture, you simply use the GetCalc(Pic1) command, and a photograph from the camera will be stored as picture Pic1 on the calculator. You can also read and write the M64282FP's registers as TI lists (arrays), allowing the calculator to adjust parameters like brightness and contrast.
More pictures and documentation about this project can be found at the link below, including the firmware and wiring information to build this project yourself. I challenge you to try building this so you can take your own 128x123 or 64x64-pixel photos with your calculator!

Cemetech Contest #13: "Games with Cats & Space"
Published by elfprince13 on November 25, 2014 at 11:47:08 PM CST | Discuss this article (21)
Another fun-filled Cemetech contest starts today! Running for about four weeks, this contest has a few unique requirements intended to exercise your creativity. For Cemetech Contest #13, you must create a game that (somehow) incorporates two elements: cats and space. It will be up to you, the contestant, to determine how best to integrate these two thematic elements within the creative fabric of your game. This contest will run through December 20th, 2014, and covers almost all of the calculators and languages with which you may enjoy programming:
So what are you waiting for? Getting coding, make a fun game, challenge yourself to learn something new in the process, and win some calculators!
Contest #13 Rubric
Contest #13 Rules
Two of the remaining four of these six generously-donated calculators will be awarded as prizes, with the remainder awarded for another upcoming contest. A special thanks to our anonymous donor for making this contest possible!
