GUI Version:

GUI Version possible because of the Dear ImGui library developed by ocornut (https://github.com/ocornut).
ImGui parts are licensed under MIT License.
Checkout imgui at https://github.com/ocornut/imgui .

a. Requires the installation of libglfw3 (on Raspbian, execute sudo apt install libglfw3-dev).
b. If you are connecting over SSH, enable X11 Forwarding by doing ssh -Y <user>@<ip> or ssh -Y <HOST> where HOST is defined in ~/.ssh/config.
c. Execute make, it should build successfully.
d. Execute sudo ./main.out, it should start the GUI program.

In case you meet an error "Could not open DISPLAY", ensure the DISPLAY variable is set to <ip of computer you are SSH-ing from>:0.
For example, execute export DISPLAY=192.168.1.12:0 if your client IP is 192.168.1.12.



CLI Version:

Requires libncurses built with multithreading support. To install:

a. Obtain ncurses from https://ftp.gnu.org/pub/gnu/ncurses/ncurses-6.2.tar.gz (using wget https://ftp.gnu.org/pub/gnu/ncurses/ncurses-6.2.tar.gz)
b. Extract the files (tar -xf ncurses-6.2.tar.gz)
c. Go into the directory (cd ncurses-6.2)
d. Configure with pthread and reentrant options (./configure --with-pthread --enable-reentrant)
e. Execute make (on RPi use 4 threads: make -j4)
f. Install: sudo make install

Now you can run make curses to execute the program.

Notes: 
1. To clone with all submodules (device drivers), execute git clone --recurse-submodules.
2. If changes are made to submodules,
    a. cd into submodule directory and commit using usual means
    b. To push submodule changes, execute git push origin HEAD:master
    c. Finally, after pushing ALL submodule changes, return to root of the repo and commit the changes of submodules relative to the main repo.
3. To pull the changes to the repo along with the repositories, use git pull --recurse-submodules
