The fxSDK is a development kit for CASIO graphing calculators in the fx-9860G and fx-CG 50 families. It provides command-line helper tools and build systems for add-ins and libraries, and is commonly used to develop add-ins running the gint kernel.
The fxSDK is free software; you may use it for any purpose, share it, modify modify it and share your changes. No credit required, but please let me know!
The fxSDK is compatible with Linux and has been successfully built on Mac OS. If there are compatibility issues, I am willing to try and port stuff to your favorite operating system. Windows users have good support with WSL.
The simplest way to install the fxSDK is to use GiteaPC, an automation tool that builds and installs repositories from Planète Casio's Gitea forge.
% giteapc install Lephenixnoir/fxsdk
The fxSDK depends on the
sh-elf-gcc compiler so
GiteaPC might build it too as a dependency. You will also need the PIL library
for Python, as well as libusb and optionally UDisks2 for fxlink. Use the
:noudisks2 to disable UDisks2-based features.
# On Debian, Ubuntu, WSL and the like: % sudo apt install python3-pil libusb-dev # (Optionally) udisks2 # On Arch Linux, Manjaro and the like: % sudo pacman -S python-pillow libusb # (Optionally) udisks2
fxsdk command to manage projects. You can create an empty add-in
fxsdk new and a name for a new folder:
% fxsdk new MyAddin
From that folder, you can build the add-in with the build commands:
# Build the add-in for fx-9860G (.g1a): % fxsdk build-fx # Build the add-in for fx-CG 50 (.g3a): % fxsdk build-cg
A tool called fxos used to live here and has now moved to its own repository.
Project management with
fxsdk lets you set up projects almost instantly with a default folder
structure and a build system for both fx-9860G and fx-CG 50. The default build
system is CMake since version 2.3, and a bare-bones Makefile is also supported.
fxsdk only writes files at project creation time, so you keep control over
your build system and configuration - it just helps you get started faster.
Summary of commands (
fxsdk --help for details):
fxsdk new: Create a new project
fxsdk build/build-fx/build-cg: Configure and compile add-ins and libraries
fxsdk send/send-fx/send-cg: Install files to the calculator (WIP)
G1A file generation with
fxg1a is a versatile g1a file editor that creates, edits and dumps the header
of fx-9860G add-ins files. It is used to build a g1a file out of a binary
It supports PNG icons, checking the validity and checksums of the header, repairing broken headers and dumping both the application data and icon.
fxg1a is called automatically by the build system in your add-in, so you
don't need to worry about it, but here are the main commands:
fxg1a -g: Generate g1a files
fxg1a -e: Edit g1a files
fxg1a -d: Dump metadata, checksum, and icon
fxg1a -r: Repair control bytes and checksums for broken files
fxg1a -x: Extract icon into a PNG file
Asset conversion with
fxconv is a programmable asset converter that converts images, fonts and
other common asset types into data structures usable directly in add-ins. The
built-in formats include gint images and fonts, libimg
images, and binary blobs.
Projects can extend the support to custom types for maps, dialogs, GUI
descriptions, or other application-specific assets. Extensions to
implemented in Python within the project.
fxconv can be used directly on the command-line but normally you specify
fxconv-metadata.txt and let the build system do the magic.
USB communication with
fxlink is a USB communication tool that can be used to send files to
calculators as well as to communicate with gint's USB driver from an add-in.
Currently, the tool is a work-in-progress, and most of the work has been spent
in properly detecting, characterizing and filtering connected calculators.
The main backend is libusb. With libusb,
fxlink can detect CASIO calculators
connected through USB and has a test mode used to prototype interactions with
fxlink also supports a UDisks2 backend for systems that have UDisks2; with
fxlink can detect Mass Storage calculators (essentially the
fx-CG series and the G-III series) connected through USB, mount them without
root access, and transfer some files all from the command-line.
The fxSDK is platform-agnostic; a single install will cover any target platforms. Here are the dependencies:
First configure; usual options are:
-DCMAKE_INSTALL_PREFIXto change the install folder;
-DFXLINK_DISABLE_UDISKS2=1to disable UDisks2 support in
% cmake -B build
Then make and install as usual.
% make -C build % make -C build install
If you selected an install folder for which you don't have write access (which
apparently includes the default folder on Mac OS), you will need
