Getting Started

Installing the CE Toolchain

  • Download the file prefixed with your OS type from here.

  • Extract the zip archive to a path without any spaces in it.

On Windows

  • Double click cedev.bat inside the extracted 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 an example of how to do this.

On Linux or macOS

  • Extend the PATH environment variable to point to CEdev/bin by modifying .bashrc, .zshrc, or whatever flavor your OS uses.

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


The toolchain requires the installation folder and any project folders to not contain any spaces. This is a limitation of the make command.

Building Programs

Programs are built with the make command, executed from a terminal session. This tutorial explains how to use the CE Toolchain to build programs using make.

Locate the installed CEdev folder, and open a build session by double-clicking cedev.bat on Windows or launching your favorite terminal 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 various programs. Navigate the to the hello_world example inside this folder using the command cd hello_world.

Type make and press enter. This command invokes the compiler, assembler, and linker creating the file bin/DEMO.8xp. The file stores the machine code of the program in a format fit for the calculator.


On Windows, you may need to install the latest Microsoft Visual C++ Redistributable package if you encounter errors such as Missing vcruntime140.dll. The download can be found at this link, depending on your computer you will need to install one of vc_redist.x86.exe, vc_redist.x64.exe, or vc_redist.arm64.exe.


On Windows, your 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 errors such as being unable find/run the fasmg program when building. It is recommended you whitelist or disable scanning in CEdev/bin to prevent these false positives from occurring.

The CEmu emulator can be used to run the program, or you can transfer it to a real calculator using the cross-platform TI Connect CE.

Building the Hello World example

Building the Hello World example

Each CE Toolchain project has the following folder structure:

  • 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.


    • 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 is not required, but can be useful for creating testable code coverage.
