Issue Date: 20th November 2014 Hand-in Date: 12th January 2015 (changed from 8th January 2015 due to Blackboard maintenance) Hand-in Method: Online (Blackboard) Programmes: BEng. (Hons) Electrical and Electronic Engineering You should submit the following: Task 1) Please submit a short report indicating the functionality of your application. Include in this report your program design. You should also submit your assembly file (.ASM file) so I can verify its operation in picsim. The assembly file should include comments and compile successfully using gpasm. If you do not submit this file you will automatically be awarded 0% out of 50% for the program implementation. Task 2) You should submit a short report of 3 pages or less The completed reports and flow charts should be saved as pdf files These pdf files, along with the commented source code file should be zipped and submitted via blackboard Coursework Specification Scenario AlockCo, the leading cabinet lock maker has hired you as a new development engineer to provide digital locks for the company to complement their current key locks. They have sourced a Pic development board, the McLab1, which is the same as Board 1 within the PICSIM simulator and wish for you to develop a lock for the company using this board. You will use the PICSIM software to verify your code. The managing director, coming from a mechanical engineering does not fully understand the differences between differing standard, realtime and distributed operating systems, so has asked for a report on what these are and how they could be used within the business for future lock development. Task 1) 80% split as 30% for program design, 50% for program implementation Create an assembly application for the pic microcontroller to operate a digital lock on a filing cabinet. You should design your application using an appropriate method (flowchart/pseudo code) and then implement this on PICSIM board 1. The specification of what is required is as follows: ? ? ? ? ? ? You will use two buttons (RA1 and RA2) to cycle up and down the 16 codes available, and use a third button (RA3) to select that code. You will display the code as an LED bit pattern on portB (bits 0:3) If the code is incorrect you will increase a counter which is also shown on portB (bits 6:7), but only if the lock is closed, if it is already open then you will not increase the counter. On the third unsuccessful code you will permanently lock the device, so your input buttons stop working. (to restart the lock you will need to use the RESET button) If the code is OK when selected you will open the lock (shown by turning on the RA0 LED), if there have been any unsuccessful attempts, then this counter will be cleared. To close the lock, you will need to set the correct code then press the OK button again, also turning off RA0. If the lock is open, you can change the code by selecting a new code using the up and down buttons then pressing RA4. You should provide the details of any assumptions made. Task 2) 20% Provide a short report (maximum 3 pages including references) to the managing director that answers the following questions: What are the differences between the following operating systems (max 1.5 pages) ? ? ? General Purpose Operating System Real-time Operating System Distributed Operating System What advantages would there have been to utilising a Real Time Operating System in this project? Would there be additional costs resulting from the implementation of Real Time Operating Systems? In the future the company would like to include computer network connectivity to the lock controller. What would be the impact of not using operating systems to complete this task?

Requirements clearly covered. Formatting is accurate Assembly Code Design – Does the diagram provide an accurate representation of the operational requirements? Is the diagram clear and well structured? Does the annotation of the diagram follow standards Diagram fails to capture the requirements of the system. Assembly Code –- Is the code written using a formal notation. Is the code well written? Does your application meet the requirements set out in the requirements specification Application provides little of the required functionality, there is little structure and few comments Application provides some of the functionality required. Is moderately well written. With few comments Application code performs most of the requirements. Little formal notation and structure. Application performs as per the requirements. Some structure and comments. Application meets the requirements is well written i.e. not verbose. Makes good use of comments. Operating system report – Is the report well written does it address the questions posed? Discussion is missing or very limited and demonstrates that the student does not have a clear understanding of the questions Discussion is limited and demonstrates that the student has only a basic understanding of the questions Discussion is of a satisfactory standard and demonstrates that the student has a clear understanding of questions Discussion is of a high standard and demonstrates that the student has a good understanding of the questions external sources have been referenced Discussion is of an excellent standard and demonstrates that the student has a deep understanding of the questions a good range of external sources have been used.
