About

Upsilon is a fork of Omega, an user-made OS that runs on the NumWorks calculator, which brings many features to it, but was discontinued because of a policy change from NumWorks. Upsilon is for the people who want to see a future for user-made OSes for NumWorks, even after the closure and archiving of Omega.

Some new features

  • Enhancements for the Kandinsky python module
  • Support for wallpapers
  • External apps
  • A custom theme
  • Operator overload for python
  • Improvements for the Periodic table application
  • And everything that has been added to Omega before its termination! See Omega's changelog here | Main Omega features + screenshots.

Installation

Installer

Go to the Upsilon website to the "Install" section. If your calculator is recognized, contains a version of Epsilon lower than 16 and your browser accepts WebUSB, the page will suggest you to install Upsilon. Do not disconnect your calculator until the installation is complete.

Manual

You can refer to this website for the first step if you get errors.

1. Install SDK


1.1 Linux
Debian or Ubuntu

You just have to install dependencies by running these command with superuser privileges in a Terminal:

apt-get install build-essential git imagemagick libx11-dev libxext-dev libfreetype6-dev libpng-dev libjpeg-dev pkg-config gcc-arm-none-eabi binutils-arm-none-eabi

And there you can go to step 2!


Fedora

To install all dependencies:

dnf install make automake gcc gcc-c++ kernel-devel git ImageMagick libX11-devel libXext-devel freetype-devel libpng-devel libjpeg-devel pkg-config arm-none-eabi-gcc-cs arm-none-eabi-gcc-cs-c++

Nix or Nixos

To install all dependencies:

nix-shell -p gcc libpng libjpeg xorg.libX11 pkg-config freetype xorg.libXext python3 imagemagick python310Packages.lz4 python310Packages.pypng python310Packages.pypng gcc-arm-embedded


1.2 Mac

It's recommended to use Homebrew. Once it's installed, just run:

brew install numworks/tap/epsilon-sdk

and it will install all dependencies.


And there you can go to step 2!


1.3 Windows
With Msys2/Mingw (officialized by NumWorks but with a lot of bugs)

Msys2 environment is recommended by NumWorks to get most of the required tools on Windows easily. It's where you'll paste all the commands of this tutorial. Once it's installed, paste these commands into the Msys2 terminal.

pacman -S mingw-w64-x86_64-gcc mingw-w64-x86_64-freetype mingw-w64-x86_64-pkg-config mingw-w64-x86_64-libusb git make python
echo "export PATH=/mingw64/bin:$PATH" >> .bashrc

Next, you'll need to install the GCC toolchain for ARM. When prompted for an install location, choose C:\msys64\home\User\gcc-arm\. You'll then need to add this folder to your $PATH. Just enter:

echo "export PATH=$PATH:$HOME/gcc-arm/bin" >> .bashrc

Just restart terminal and you can go to step 2!

With WSL 2

You need a Windows version >= 1903.

WSL Installation

  1. Use simultaneously Win + X keys and then click on "admin powershell".
dism.exe /online /enable-feature /featurename:Microsoft-Windows-Subsystem-Linux /all /norestart

This command activate WSL functionalities.

dism.exe /online /enable-feature /featurename:VirtualMachinePlatform /all /norestart

This one allows virtual machines developed by Microsoft.

  1. Restart your computer.

  2. Download this file and follow instructions.

  3. Now open powershell admin like before and type:

wsl --set-default-version 2
  1. Download Ubuntu from Microsoft store.

WSL is now installed.

  1. Then install GCC cross compiler for ARM.
apt-get install build-essential git imagemagick libx11-dev libxext-dev libfreetype6-dev libpng-dev libjpeg-dev pkg-config gcc-arm-none-eabi binutils-arm-none-eabi

Usbipd installation to connect your calculator

If you want to connect to the calculator, you have to connect to install this tool. This will allow you to connect WSL to the calculator through internet. Follow the on screen information to install.

Ubuntu

  1. In a WSL Ubuntu command prompt, type:
sudo apt install linux-tools-5.4.0-77-generic hwdata
  1. Edit /etc/sudoers so that root can find the usbip command. On Ubuntu, run this command.
sudo visudo
  1. Add /usr/lib/linux-tools/5.4.0-77-generic to the beginning of secure_path. After editing, the line should look similar to this. Defaults secure_path="/usr/lib/linux-tools/5.4.0-77-generic:/usr/local/sbin:..."

Debian

  1. If you use Debian for your WSL distro, use this command instead:
sudo apt install usbip hwdata usbutils

And that's all for installation and set up.

To connect your calculator

  1. Open an admin PowerShell and type:
  usbipd wsl list

This will list your USB devices connected. Look at the BUSID column and remember the one for your calculator (it should be called "Numworks Calculator"). 2. Now run this command replacing <BUSID> by your calculator's USB port id:

usbipd wsl attach --busid <BUSID>

It will ask you to type your WSL's password and will connect your calculator to WSL.

You can now go to step 2!


2. Set up repo

Clone repo and use 'upsilon-dev' branch by pasting these two commands:

git clone --recursive https://github.com/UpsilonNumworks/Upsilon.git
cd Upsilon
git checkout upsilon-dev

3. Choose the target

Model n0100

(note: you can change the EPSILON_I18N=en flag to fr, nl, pt, it, de, es or hu).

make MODEL=n0100 clean
make MODEL=n0100 EPSILON_I18N=en OMEGA_USERNAME="{Your name, max 15 characters}" -j$(nproc)

Now, run either:

make MODEL=n0100 epsilon_flash

to directly flash the calculator after pressing simultaneously reset and 6 buttons and plugging in.


or:

make MODEL=n0100 OMEGA_USERNAME="" binpack -j$(nproc)

to make binpack which you can flash to the calculator from TI-Planet's WebDFU. Binpacks are a great way to share a custom build of Upsilon to friends.

Model n0110

The bootloader allows you to install 2 firmwares in separated "slots". If so, external apps won't have all the space but half. Bootloader will allow use of all of the memory if only one slot is flashed. In legacy mode, external apps use all the space available.

Bootloader

Your calculator must already have been flashed with Upsilon's or Omega's bootloader. Then, build with:

make clean
make OMEGA_USERNAME="{Your name, max 15 characters}" -j$(nproc)

Now, run either:

make epsilon.A_flash

to directly flash the calculator into the current slot, or thought bootloader's slot flasher with RESET, then 4 (flash), and 1 (flash slots) for other slots.


or:

make OMEGA_USERNAME="" binpack -j$(nproc)

to make binpack which you can flash to the calculator from TI-Planet's webDFU. You'll find them at output/release/device/bootloader/. Binpacks are a great way to share a custom build of Upsilon to friends.

Model N0110 legacy (deprecated, use bootloader instead for Epsilon protection) 
make MODEL=n0110 clean
make MODEL=n0110 OMEGA_USERNAME="{Your name, max 15 characters}" -j$(nproc)

Now, run either:

make MODEL=n0110 epsilon_flash

to directly flash the calculator after pressing simultaneously reset and 6 buttons and plugging in.


or:

make MODEL=n0110 OMEGA_USERNAME="" binpack -j$(nproc)

to make binpack which you can flash to the calculator from Ti-Planet's WebDFU. You'll find them at output/release/device/bootloader/. Binpacks are a great way to share a custom build of Upsilon to friends.

Native simulator

Run this command:

make clean

You can either build using the following command that will automatically detect your platform:

make PLATFORM=simulator

or, choose the command corresponding to your platform:

make PLATFORM=simulator TARGET=android
make PLATFORM=simulator TARGET=ios
make PLATFORM=simulator TARGET=macos
make PLATFORM=simulator TARGET=web
make PLATFORM=simulator TARGET=windows
make PLATFORM=simulator TARGET=3ds

You'll find simulator files in output/release/simulator/.

Web simulator

First, install emsdk :

git clone https://github.com/emscripten-core/emsdk.git
cd emsdk
./emsdk install 1.40.1
./emsdk activate 1.40.1
source emsdk_env.sh

Then, compile Upsilon :

make clean
make PLATFORM=simulator TARGET=web OMEGA_USERNAME="{Your name, max 15 characters}" -j$(nproc)

The simulator is now in output/release/simulator/web/simulator.zip

3DS Simulator

You need devkitPro and devkitARM installed and in your path (instructions here)

git clone --recursive https://github.com/UpsilonNumworks/Upsilon.git
cd Upsilon
git checkout upsilon-dev
make PLATFORM=simulator TARGET=3ds -j$(nproc)

You can then put epsilon.3dsx on a SD card to run it from the HBC or use 3dslink to launch it over the network:

3dslink output/release/simulator/3ds/epsilon.3dsx -a <3DS' IP ADDRESS>

Casio fx-CG-series Port

First, install gint and fxsdk along with a cross compiler for the calculator. There are instructions for this (in French, but Google Translate works well enough) here.

Next:

git clone --recursive https://github.com/UpsilonNumworks/Upsilon.git
cd Omega
git checkout upsilon-dev
make PLATFORM=simulator TARGET=fxcg -j$(nproc)

Then copy the file at ./output/release/simulator/fxcg/epsilon.g3a to the calculator over USB.

Important: Don't forget the --recursive tag, because Upsilon relies on submodules. Also, you can change the number of processes that run in parallel during the build by changing the value of the -j flag. Don't forget to put your pseudo instead of {your pseudo, max 15 char}. If you don't want one, just remove the OMEGA_USERNAME="" argument.
