Getting Started

Installing the CE Toolchain

  • Download the latest stable toolchain release below:

  • If you would rather try the “nightly” build (which includes the latest features and bugfixes before an official release) you can find it here.

On Windows

  • Extract the zip to a folder without any spaces in the full path, e.g. C:\CEdev.

  • Double click cedev.bat inside the extracted CEdev folder to launch the toolchain environment. You may have to allow the script to be run depending on the user account control.

  • If you want to avoid using the cedev.bat script, you can extend the PATH environment variable to point to the CEdev/bin directory. Here is a guide.

On Linux or Mac

  • Extract the archive to a path without any spaces, e.g. /home/user/CEdev.

  • Extend the PATH environment variable to point to CEdev/bin by modifying .bashrc, .zshrc, or whatever flavor the OS uses. An example command may be:

    export PATH=/<insert path here>/CEdev/bin:$PATH

Tip

The toolchain update process is the exact same as installation - the only extra step is to delete the current CEdev folder if it exists beforehand.

Building Programs

Open a build session by double-clicking cedev.bat on Windows or launching a terminal session on Linux/macOS. Navigate to the examples folder using the cd examples command. This folder contains example projects that you can build and modify to learn how to write different programs. Navigate the to the hello_world example project using the command cd hello_world.

Type make and press enter. This command invokes the compiler, assembler, and linker creating the program bin/DEMO.8xp. Use the CEmu emulator to run the built program, or transfer it to a real calculator using TI Connect CE.

Note

If on Windows you encounter errors such as Missing vcruntime140.dll, install the latest Microsoft Visual C++ Redistributable package. The download can be found at this link, depending on the architecture you will need to install one of either vc_redist.x86.exe or vc_redist.x64.exe.

Tip

Antivirus software (e.g. Windows Defender) may flag binaries in the CEdev/bin directory as false positives, and either quarantine/remove the files or prevent them from running. This may result in build errors such as being unable find/execute fasmg. Please whitelist or disable scanning in CEdev/bin to prevent these false positives from occurring.

Project Structure

Every CE Toolchain project has the following folder structure. It is highly recommended to keep the same structure to ensure that your project can build with future toolchain versions.

src

This is the directory where all source files can be placed. Sources are built automatically if they end in a .c/.cpp extension, and can be edited with any text editor or IDE. Subdirectories are allowed as long as they do not contain spaces.

obj

Compiled C/C++ files are placed here, and contain intermediate assembly output.

bin

This is where the final linked calculator program will be placed, ending with a .8xp extension.

makefile

A text file used by make to build the program. There are options for setting the program name, description, and more.

icon.png

This is a 16x16 icon that is displayed in shells such as Cesium.

readme.md

A text file that describes the program’s operation.

autotest.json

This file can be loaded into CEmu’s Autotester to test and validate the program. This feature may be useful for creating testable code coverage.
