#Ti 84 emulator setup instructions code#
The CPU includes the code to process instructions, all of the z80's registers, and most of the code to manage interrupts. Although automated tools adapted from the FUSE emulator helped simplify the process, a great deal of tweaking, optimization, and adjustment was necessary. z80 CPU: The CPU (processor) is the heart of jsTIfied, and occupies a huge amount of code.Let me tell you about each of the modules in Figure 1, how they work, and how they communicate with other pieces of jsTIfied. Larger text and larger boxes correspond to modules that require more code.įigure 1 shows that while the majority of the code in jsTIfied corresponds to physical hardware features of a TI graphing calculator, a substantial amount is also necessary for emulator-specific features and tools. Blue are modules with calculator hardware equivalents, purple are emulator-related features, and turquoise are network-dependent features. Figure 1 shows the major modules of jsTIfied, categorizing them as emulator features or calculator components.įigure 1: A flowchart of major jsTIfied components.

JsTIfied is built as a series of modules, roughly corresponding to either a major component of a graphing calculator or a major feature of the emulator.
I'll give you a very high-level overview, assuming you know the basics of computer architecture theory and practice. In order to understand how it works, you must know a little bit about how graphing calculators (or any basic embedded system) works.
Other coders' projects have demonstrated GameBoy, ZX Spectrum, and even 386 emulators in Javascript.
Browsers like Firefox even let users right-click on the canvas and save it as an image.
It was long a dream of mine to be able to create such an online emulator, but until recently, this was impossible. The jsTIfied emulator is written entirely in Javascript and HTML5. Built-in debugger and CPU/memory view for assembly programmersĬlick here to launch the jsTIfied online graphing calculator emulator, check out the video below for an overview of the major highlights, or read on for more details about how jsTIfied works.Integrated with the SourceCoder TI-BASIC IDE/editor, so that you can write programs in SourceCoder and immediately test them on a calculator.Can export all files from the emulated calculator.Drag calculator files onto the jsTIfied LCD to import them.Can take animated and still screenshots.Runs on all major browsers and operating systems.

Full TI-83+/TI-84+ emulation including accurate LCD physics for good-looking grayscale.As a full calculator emulator, it offers lots of features: For legal reasons, you must load your own ROM image, which is stored in your browser and never sent to the Cemetech server. It runs entirely in your browser using HTML5 and Javascript, so it requires neither Java nor Flash.
