Division of Computing Science and Mathematics Assignment 2 Semester: Spring Year: 2019-20 Module Title: Systems Module Code: CSCU9V4 Tutor: Dr Deepayan Bhowmik Division: Computing Science Submission date: 5:00 pm, Wednesday 8th April 2020 Demonstration date: 10:00 am – 4:00 pm, Thursday 9th April 2020 Nature of Task & Brief Description: You have done the circuitry for the ‘Why-Aye’ Pad controller in Assignment 1. You also have had experience with C in the lab. In this assignment you need to develop algorithms in C to simulate the controller algorithm. This is an individual assignment. Max number of members in one group 1 Assessment Weighting: 20 % Objectives This assignment is designed to address the following learning outcome of the module : ▪ Develop algorithms using C programming language. Task Details: The finished assignment must: a) Complete all tasks as described below. b) Demonstrate that the code works. c) Answer question to demonstrate your understanding. d) Submit the code through CANVAS. Division of Computing Science and Mathematics Assignment Specification The Wi-iTM Controller Number 910 Fulchester Road in Newcastle is a famous address in the games industry. Whilst other provincial games manufacturers took on the big guns in the games industry with products such as the Phony PlaySatan to compete with the iPhone, and the Welsh assembly-supported X-Cist 360 and ‘GameBoyo’ (as ‘leeked’ to the press recently), a small business operating out of a terraced house in the North East of England decided to call its revolutionary new product after the digits in their house number. Thus was born the NineTenDoor Wi-i (pronounced, as expected in Newcastle, “Why- Aye”). This somewhat radical new console was designed to be used by inebriated players, and so had a ruggedised minimalist controller with only 4 buttons, as shown opposite. This was dubbed the ‘Eee!’, reflecting the uncalled-for enthrall when first seen by a drunk game-player. Games soon appeared for this new console, such as “You’re Me Best Mate!” a bus-station-platform game, and “Down The Bigg Market”, a multi-person, free-for-all, shoot and stab ’em up. “Are You Looking At Me?” and “You’ve Spilled Me Pint!” soon followed, followed by ports of popular games such as “Spore” but with just the first level available, as deemed appropriate. Shoot ’em Up’s, educational games warning of the perils of drunken drug abuse. The controller’s buttons are designed to be used singly, or in combination with one or two of the others. There are 14 possible combinations with 2 ‘no operations’ – it was decided that pressing all four simultaneously was probably not only impossible for a drunkard, but insensible in terms of game play. The buttons control a sprite in a game (we’re not concerned with the game’s details here) in the following way: no buttons nothing happens! move left (L) rotate anti-clockwise (ACW) move right (R) rotate clockwise (CW) + move down (D) + move up (U) + rotate anticlockwise (ACW) & move left (L) simultaneously + rotate clockwise (CW) & move left (L) simultaneously + rotate anti-clockwise (ACW) & move right (R) simultaneously + rotate clockwise (CW) & move right (R) simultaneously ++ rotate anticlockwise (ACW) & move down (D) simultaneously ++ rotate anticlockwise (ACW) & move up (U) simultaneously ++ rotate clockwise (CW) & move down (D) simultaneously ++ rotate clockwise (CW) & move up (U) simultaneously +++ nothing happens! Figure 1: Button control details Wi-iTM Division of Computing Science and Mathematics YOUR TASKS Task 1: Develop algorithm written in C that simulated the behaviour of the Wi-i controller as described in Figure 1 (Button control details). The user should be able to press the number buttons or arrows keys on the keyboard. Display the output on ‘terminal’ (equivalent to ‘command window’ on a Windows desktop). The code should run in a continuous mode and special key input should be used to terminate the program. Task 2: Improve your task 1 by displaying graphical representation on the console. For example, if your key combination indicates ‘Move left’ you can display a ← shape (which is composed of a number of simple characters like ‘*’, ‘+’, ‘-‘, ‘x’, or ‘how to display this innovatively. Task 3: Read humidity, pressure and temperature values from the files provided. Read them continuously and display on the terminal in the following order: 1. Pressure (P), 2. Humidity (H), 3. Temperature (T). Extend the code so that the user have option to change the order of this display during the run time. For example if someone press 0 it will prompt the user to enter display order in this format, PHT or HTP or TPH. This input should NOT be case sensitive. Based on the user input the display should change its order on the terminal. For example if the input is HPT then the display should be 1. Humidity (H), 2. Pressure (P), 3. Temperature (T). User should be able to do this as many times as they want without terminating the program. If data finishes in any of the files it should start reading from the beginning again. Task 4: [This is an optional component and should only be attempted after other tasks are complete.] Create a bitmap image file of a plain colour (called “mydraw.bmp”). Modify the bitmap file to let it display the graphics you draw in the console window in Task 2. You should not change the file name. Apart from doing some extra reading on your own, you may refer to the following webpage about how to write code to read, write and crop BMP image files: https://engineering.purdue.edu/ece264/17au/hw/HW15 Task 5: Demonstrate your code successfully for tasks above. Students will be questioned regarding the assignment and related understanding. Demonstration viva will be conducted for each student. Marks will be given based on individual performance for this task. Division of Computing Science and Mathematics Task 6: You need to submit a document which will have individual flowchart for Tasks 1-4. You should follow flowchart conventions for this task. Task 7: You also need to submit the code for Tasks 1 – 4. Higher marks will be award for efficient coding practices. This includes better use of pointers, modular code design such as more use of functions etc. Code should be well commented and well formatted. M
arks will be deducted if this is not maintained. Outcomes This work is designed to test your understanding of C programming. Pro-rata marks will be awarded depending on how many tasks you have completed, how efficiently you have coded and how creative you have been with tasks for better user interface. Submission You will need to submit your work on Canvas as a ZIP file bearing your university username (3 letters + 5 digits, e.g., xyz00001.zip). • This is individual work. The deadline for this assignment is 5:00 pm on Wednesday 8th April 2020. Demonstration: 10:00 am-4:00 pm on Thursday 9th April 2020
