1 UNIVERSITY OF ULSTER UNIVERSITY EXAMINATIONS : 2001/2002 RESIT Year 2 MICROCONTROLLER SYSTEMS Module Code: EEE305J1 Time allowed: 3 Hours Answer as many questions as you can. Not more than TWO questions from Section B will contribute to the final mark. Use separate answer books for each section. A PIC16 FXXX instruction set appears at the end of this paper A CCS C compiler reference card appears at the end of this paper 1/8 Module Co-Ordinator: Dr S J Katzen

2 SECTION A Q.A1 A certain dishwasher has four wash programmes, which are determined on reset (the power ON/OFF switch) by the setting of four front-panel switches labelled AUTO, ECONO, QUICK and RINSE. To allow the user some time to make up his/her mind, these switches are continually scanned nominally every four milliseconds and if a switch is set, the pattern stored in a file register. After 256 scans (approximately one second), the PICI6F84 microcontroller lights a green LED above the last closed switch, a buzzer is sounded for around 100ms and the processor calls the appropriate subroutine called AUTOMATIC, ECONOMY, QUICK_WASH and PRE_RINSE, unless no switch is closed in which case the scan continues until a switch is closed. Pertinent hardware details are: A closed switch gives a logic 0 Each LED requires a nominal current of 20 ma. The buzzer requires five volts to activate. The PIC16F84 is clocked using a 4 MHz crystal and powered with a 5v supply. You are asked to design both input and output interface circuitry for the switches, buzzer and LEDs, and software for the system to implement the following scheme. Questions (1), (2) and (3) should be illustrated with a diagram and any necessary parallel port software configuration shown at that point in your answer. (1) The input interface for the four Programme-Select switches, including any necessary resistors and their nominal value. [6 marks] (2) The output interface for the four green LEDs. Determine the value of the current-limiting resistors and state if the LED is illuminated by a logic 0 or logic 1. [8 marks] (3) A single output line to drive the buzzer. [2 marks] (4) An algorithm and assembly-level code as specified below. You can assume that all file registers between 20h and 2Fh are free for general variable storage. (a) A main routine to: (i) initialise the system; 2/8

3 (ii) loop every four milliseconds using subroutine (b) below reading the Programme-Select switches and storing the pattern in a File register if any switch is closed; (iii) breaking out of the loop after 256 reads; (iv) test each bit in the File register of (ii), calling the BUZZER subroutine of (d) below if a logic 0 is found, lighting the corresponding LED and finally calling up the appropriate subroutine AUTOMATIC, ECONOMY, QUICK_WASH or PRE_SCALE. You can assume that these subroutines are in position; you do not have to write them; (v) if a logic 0 is not found then read the switches until a closed switch is found, store in the File register and repeat (iv). [27 marks] (b) A subroutine to give a fixed nominal 4 ms delay. [9 marks] (c) A subroutine based on (b) above to give a nominal 4 n ms delay, where n is an integer (0-255) passed to the subroutine in the Working register. [5 marks] (d) A subroutine to turn on the buzzer for nominally 100ms using subroutine (c) above. [3 marks] (5) What change could you make to your software so the washing programme selected will be that the user selected the last time the dishwasher was switched on, if a new switch is not closed during the initial scan period? [5 marks] (6) Write a main()function in the C language to implement the code of 4 (a) above. You can assume functions buzzer(), automatic(), economy(), quick_wash() and pre_rinse() are available in position, you don t need to write them. Also available is the function delay_ms(n)as listed in the CCS compiler reference card at the end of this paper. [25 marks] 3/8

4 SECTION B Q. B2 (a) The ASCII code for the symbol? is 0x3F. If this character is to be transmitted using the RS232 protocol at 9600 baud with 8 data bits, no parity and one stop bit draw a waveform annotated clearly with time and voltage that represents what you would see if an oscilloscope was monitoring the RS232 transmit line. [8 marks] (b) If a device receiving an RS232 transmission is incapable of processing the incoming data fast enough several techniques can be employed to allow the receiver to slow down the transmission character rate; these include hardware handshake and software handshake. Describe, using diagrams, either of these methods. [12 marks] Q. B3 (a) Analogue to Digital convertors (ADCs) are used to convert varying signals to a numeric representation of fixed precision. An 8 bit ADC that can convert a voltage of 0 to 5 volts is to be used in a data acquisition system. A sensor produces a signal that ranges from 10 millivolts to + 10 millivolts. Sketch a suitable system that can be inserted between the sensor and the ADC to maximise the resolution of the system. [8 marks] (b) Describe using diagrams at least four types of ADC. [12 marks] Q. B4 (a) A 8 bit digital to analogue convertor (DAC) is to be used to implement a ADC. The DAC analogue output is fed to one input of an analogue comparator, the other input connects to a sensors analogue output. A PIC microprocessor can output an 8 bit number of port B to the DAC and sense port A, bit zero to see if its output number is greater than the input. Sketch a flowchart of how a PIC might guess or work out a number that can represent the inputs value. (Hint: work through each bit in turn, beginning with the MSB). [13 marks] (b) If each instruction takes one microsecond, how long will the algorithm in part (a) take to execute? [7 marks] 4/8
