3 This repo contains git submodules with all source code of this coffee
4 terminal. Fetch it with:
6 git submodule update --init
8 The `coffee-flask` directory contains the server application, which
9 runs on [rtime](https://rtime.felk.cvut.cz/coffee) server.
11 `terminal` directory is the code running on the terminal. It is a
12 standard buildroot distribution. The most importat piece of code here
13 is the `mtaio` application from `terminal/src/mt-apps`.
15 A more detailed documentation is available in [Jiří Matěják's Master
16 thesis](https://dspace.cvut.cz/handle/10467/76276).
20 Data collected by the terminal are stored in an sqlite database on the
21 rtime server. Users with SSH access to that server have read-only
22 access to the database. For example, the whole database can be dumped
25 sqlite3 /home/coffee/coffee-flask/coffee.db .dump
27 ## Hacking on the code
29 To improve the terminal, you can run all the relevant code on your
32 First install all prerequisities:
34 apt install python3-flask libev-dev cmake
35 pip3 install flask_cors
37 Then compile and run all the software components:
39 1. Compile _mtaio_ simulator: `make -C terminal/src/mt-apps SIM=1`
40 2. Run mtaio: `cd terminal/src/mt-apps && ./build/mtaio`
41 3. Run the server application: `cd coffee-flask && FLASK_APP=app.py flask run`
42 4. Point your web browser to http://localhost:8080/
43 5. Pressing keys in _mtaio_ window simulates various activities.
