Assignment for Credit
Course Code : ENG 5220 Course Name : Real Time Embedded Programming
Type : Technical Report
Oral Presentatton & 
Public relattons
Title of Assignment : Development, design, constructton and 
promotton of a product requiring realttme operatton
% of ffnal course mark : 100% Lecturer : Bernd Porr & Chongfeng Wei 
Marking
1. 10% will be awarded for the inittal pitch of the project (every team has 5 mins and two slides) 
and inittal github pages up and running (special ttmeslot, see moodle). We assess here the 
originality/usefulness of the work, if it has a solid realttme requirement and the quality of the 
presentatton. 
2. 25% of the credit for the ffnal submitted work will be based on the way the code is 
structured, that it is divided up in classes allowing encapsulatton of data, using data 
structures in a failsafe way, receiving data and releasing data in a safe way and in general 
guaranteeing high reliability and ease of maintenance.
3. 30% of the credit for the ffnal submitted work will assess the realttme coding of the soffware 
and how this has been achieved. This includes whether processing of events has been 
achieved by waking up threads and in general employing event driven code using callbacks, 
ttmers, signals, threads, and/or kernel space interrupt driven coding in preference to polling 
or other less suitable methods.
4. 25% of the credit for the ffnal submitted work will be based on the use of revision control, 
committtng, branching, creattng releases, testtng and project planning. Marks will be 
awarded for demonstrattng clear division of labour and documentatton of the work. Has git 
been used as a revision control system or just to ``upload'' code? Has git been used to do 
revisions, track bugs and has there been a release strategy? Has the issue tracker system 
been used? Have unit tests been used?
5. 10% of the marks are devoted to the promotton of the work: has the project been properly 
presented on github so that it catches the eye of a potenttal user? Is the hard/soffware 
described in a way that other people can reproduce it? Has the project been adverttsed on 
social media and has it been picked up by online publicattons such as hackaday? Has a social 
media account been created and has it created a buzz around it? Has the project a license?
All items above will marked on the 22 point scale, according to the performance indicators written 
overleaf. Consideratton will be given to the inclusion of Aims and Objecttves and clarity of 
presentatton.Submission & Return
The submission is online via moodle where you provide the link to the github page which contains 
your report, code, hardware and links to social media. On the day of the deadline we will download 
the latest release from the team’s github repository and mark it. It’s the responsibility of the team to 
create a release on github by the deadline. 
Make sure that each group member’s area of responsibility is clearly marked.
Note that University policy on late submission of work without good cause is that the grade will be 
reduced by two secondary bands (e.g. from ‘B1’ to ‘B3 or ‘A5’ to ‘B2’) for each working day, or part of 
a working day, after the submission deadline. This means that if the team’s software release is 
created late on github they will receive a late submission penalty. Releases created more than five 
days after the deadline will receive an ‘H’ grade. If you are unable to submit work on time due to 
good cause, you should contact us as soon as is possible to seek a deferral.
Submission deadline : 21 April 2025, 3pm
Results & Feedback 
Feedback & results about the initial pitch will be available after the presentation.
You will receive feedback about your final work via email. This feedback will be structured according 
the 4 marking criteria above covering the final work and will comment on every section.1. Presentation

Optimal choice of 
classes (SOLID)
Classes have clear 
responsibilies, 
interfaces are 
segregated to be 
client specific, 
dependency 
inversion, obey the 
Liskov 
Substitution 
Principle and 
documented in an 
intutive way.
Classes have clear 
responsibilies, 
interfaces are 
segregated to be 
client specific, 
dependency 
inversion, obey the 
Liskov Substitution 
Principle. Minor 
issues but still 
professional 
production standard.
 Generally 
following the 
SOLID principles 
but either one is 
violated or 
documentation 
does not 
demonstrate that 
they have been 
taken into 
consideration.
Some SOLID 
principles haven’t 
been applied and/or 
there are violations 
of the principle. 
Documentation has 
flaws which makes it 
hard to see if/how 
they have been 
applied.
Serious flaws in 
the 
implementation 
of SOLID and 
most principles 
haven’t been 
applied. There is 
little mention in 
the 
documentation 
about the class 
choices.
Not clear 
whether SOLID 
has been applied 
or not. Some 
aspects appear 
to be applied but 
there is no direct 
evidence or 
documentation 
which makes it 
clear.
No application of 
SOLID or little to 
mark at all.
Encapsulation of 
data in classes 
and safe use of 
getters, setters, 
callbacks and 
data 
management.
Clear public 
interfaces are 
defined, the data is 
private and getters, 
setters & callbacks 
provide a safe 
interface to the 
client. Internal data 
structures are 
efficient and 
provide fast 
acccess / 
compuation.
Public interfaces are 
defined, the data is 
private and getters, 
setters and callbacks 
provide a safe 
interface to the 
client. However, 
some minor flaws for 
example in terms of 
safety, timing and 
choice of internal 
data structures.
Generally data is 
encapsulated and 
the internal storage 
of data is 
appropriate but 
there smaller 
issues with the 
getters / setters, 
not checking for 
fault conditions or 
the internal data 
storage could be 
more efficient.
Significant problems 
with encapsulation 
such as public 
variables and no 
fault checking. Data 
storage/management 
is inefficient.
Serious flaws in 
encapsulation 
with public 
variables being 
accessed, no 
clear getter, setter 
and/or callback 
interfaces and 
data is stored in 
not appropriate 
structures.
No 
encapsulation in 
the classes used 
but classes work 
by accessing 
variables and 
calling member 
functions. No 
use of public / 
private variables 
& members.
No classes used, 
use of global 
variables or classless
coding.
Failsafe memory 
management
Memory 
management is 
completely leak 
free.
Memory 
management is leak 
free but uses 
new/delete where it 
could be avoided.
Excessive use of 
new/delete where 
C++ instances and 
copy constructors 
could be used.
Clearly there is a 
lack of care of 
tidying up memory 
allocations.
Serious flaws of 
memory 
management with 
eventual crash.
 Serious flaws in 
memory 
management 
leading to out of 
memory.
No memory 
management at all 
or nothing to mark.3. Realtime coding

Assessment of 
latencies in the 
application 
context and 
appropriate 
design decisions
Professional 
quantitative 
assessment and 
tolerances leading 
to clear coding 
decisions
Good quantitative 
assessment of the 
realtime demands 
leading to good 
coding decisions 
with small 
omissions.
Correct assessment 
of requirements 
but smaller 
shortcomings and 
resulting smaller 
issues in terms of 
coding decisions.
 Assessment of the 
latencies partially 
wrong or not 
completely 
considered and the 
propose coding 
framework is not 
well thought 
through.
Latencies not 
seriously assessed 
and thus no 
justification of the 
realtime coding 
strategy.
Almost no effort to 
research in into 
latencies and their 
knock on effect on 
coding.

Realtime coding Production level 
realtime coding 
using 
threads/timers/sign

Solid realtime 
coding but with 
smaller coding 
issues causing 
small noticeable 
latencies.
Realtime coding 
has shortcomings in 
responsiveness, 
timing and 
sampling of 
signals. 
Significant 
shortcomings in the

Realtime event 
handling
Production level 
event coding with 
clearly defined 
callback handlers

Perfectly working 
prototype but minor 
shortfalls how 
events are passed 
on, documented or 
structured.
Solid event 
handling but with 
smaller problems 
where interface 
definitions might 
hinder segregation 
or re-use.
Event handling has 
shortcomings 
flexibility, memory 
usage, safety and 
fault detection. 
Event handling is 
buggy.
Significant 
shortcomings in 
event handling 
where instead of 
callbacks partially 
polling is used or 
other non-realtime 
approaches.
Design shows 
major weaknesses 
in even processing. 
No callbacks are

Aims
Development and promotion of a product requiring realtime operation.
Objectives
 Propose a product which requires realtime processing and solves a real world task
 Select hardware connecting to a Raspberry PI as proof of concept
 Develop realtime software in C++ as the main language (only web-pages in webbrowser
& mobile apps are allowed to use scripting languages)
 Create, maintain, schedule and document the project using git version control, tests 
and quality management
 Promote the final product via github, social media and live demos
§2 Task Requirements 
The task is to present an end user product which requires realtime processing. This will be 
build around Linux on a Raspberry PI. It needs to be a project which solves a real world 
problem, for example, watering plants while away on holiday or a mattress which senses if a 
person sleeps well. Note, that whilst creative lateral thinking is always welcome in Masters 
level courses, it is possible to take shortcuts in creating an application which mean that it is 
no longer realtime, or is otherwise trivial in nature, and thus does not show mastery of the 
Intended Learning.
In technical terms this means that the Linux system needs to measure physical values, plot 
them on the screen, allow mouse interaction to change parameters and that it generates 
meaningful outputs. All this in realtime. At the end you should have a standalone embedded 
application which boots up and performs your chosen task.
Your task is to use data acquisition hardware, for example the sound card or on the 
Raspberry PI sensor boards and digital sensors.
Main coding language must be C++. The operating system must be Linux. Code must be 
written in an object oriented fashion with a testing framework i.e. unit testing. Only web 
clients running in web browsers and mobile phone apps are permitted to be written in a 
scripting language (PHP, js, Python, JAVA, swift, ...).
The code must be event driven -- either in userspace with callbacks and/or waking up 
threads and/or interrupt driven in kernel space.
Form groups of five and every person should have a distinct role. On moodle is a wiki where 
every team enters their names, matric numbers and links to github where their entire 
project is hosted.Outcomes of the course. We set out here requirements for the work, which if you ignore will 
ensure that your project does not fulfil the brief and is liable to receive few if any marks. In 
particular the following criteria pose a strong risk that the group will receive zero marks:
• program goes into wait state and becomes unresponsive
• using wait statements to establish timing instead of switching threads, timers or load 
balancing
• not using callbacks to process events
• single threaded loop with blocking and/or delaying code
• trivial work selling just with public relations but no substance
• no indication of version control and/or git “upload” just before the deadlline
• not using C++ as the main coding language (remember scripting is only allowed for 
web clients within web-browsers and mobile phone apps)
Do not hesitate to discuss with the course co-ordinator any original approaches to the 
assignment you are worried might be off-topic and thus could attract a very low grade.
§3 Formal contact hours and independent work
You’ll spend 33 hours in the lab under supervision. There are also 11 hours of lectures you 
need to attend. In addition you’ll need to work both independently in the lab and do 
independent study in the remaining 156 hours allocated to this class. This work requires a 
high degree of independent work while the lab sessions shall be used to get advice, guidance 
and feedback from both the academics and teaching assistants.
§3 Hardware purchases
The budget is £45 per team for orders via the electronics store and/or technician.
