1 ECE Test #1: Name Closed Book, Closed Notes. Calculators Permitted. September 23, < ) Binary Inputs: Design a circuit to detect when the sun is out and when it's cloudy. Assume a light sensor has the following light vs. resistance relationship R = 100,000 Lux Ω Design a circuit which Outputs 5V when the light level is more than 100 Lux, Outputs 0V when the light level is less than 80 Lux, and Remains unchanged in-between 80 and 100 Lux. 5V 2.5V 10k 180k 1k 10k 180k 5V 0V 2.5V 10 Lux 2.778V 80 Lux Assume a 1k resistor for the volage divider: 100 Lux = 1000 Ohms = 2.5V 80 Lux = 1250 Ohms = V Gain = (5V - 0V ) / (2.778V - 2.5V ) = 18.0 When the input is large ( 5V or 0 Lux), the output is small. Connect to the minus input When the output is 0V, you switch at 2.5V. The offset is 2.5V

2 2) Binary Outputs. Design a circuit which allows a PIC to turn on and off a 10W LED at 1A. Assume the characteristics of the LED are Vf = 2A A Assume an NPN Zetex transistor with the following specifications: max(ic) = 4A Vce:sat = 200mV β=300 Assume the PIC can outputs 5V with a maximum current of 25mA Assume a +10V power supply (anything larger than 5.2V works) R c = 10V 5V 0.2V 1A = 4.8Ω To saturate the transistor βi b > I c Let Ib = 5mA I b > 1A 300 = 3.33mA R b = 5V 0.7V 5mA = 860Ω 10V V - PIC 860 1A LED + 5V V - Ib = 5mA 172 < Rb < mA < Ib < 3.33mA

3 3) Software: For a stoplight, a wait routine which takes 5 seconds to execute is desired (50 million clocks). 3a) Determine how many clocks the following wait routine takes. ans = 132,977,404 3b) Modify this routine so that it takes 50 million clocks (5 seconds) show on program Assembler Code 18 lines of assembler Wait5s: Number of Clocks 18 lines of assembler 2 b) Change to 96 movwf CNT2 C Code 89 lines of assembler void Wait(unsigned int SEC) unsigned int i; L2: movwf CNT1 2 * 255 unsigned long int j; for (i=0; i<sec; i++) for (j=0; j<130000; j++); L1: movwf CNT0 2 * 255 * 255 L0: decfsz CNT0,F goto L0 8 * 255 * 255 * 255 decfsz CNT1,F goto L1 3 * 255 * 255 decfsz CNT2,F goto L2 3 * 255 return 2

4 4) Software: Assume your PIC is connected to a stop light with RB0 = Red Light ( logic 1 = on ) RB1 = Yellow Light ( logic 1 = on ) RB2 = Green Light ( logis 1 = on ) Also assume you have a wait routine (i.e. reuse problem 3) Wait5s: which takes burns 5 seconds (50 million clocks) then returns. Write an assembler program to implement a stoplight: Assembler 37 Lines of Assembler (incl problem 3) #include <p18f4620.inc> Loop: org 0x800 clrf TRISB movlw 0x0F movwf ADCON1 movlw 0x04; movwf PORTB movlw 0x02; movwf PORTB C 169 Lines of Assembler (incl problem 3) // Global Variables unsigned char GREEN = 4; unsigned char YELLOW = 2; unsigned char RED = 1; // Subroutine Declarations #include <pic18.h> void Wait(unsigned int SEC) unsigned int i; unsigned long int j; for (i=0; i<sec; i++) for (j=0; j<130000; j++); void main(void) TRISB = 0; ADCON1 = 0x0F; while(1) PORTB = GREEN; Wait(20); Start Initialize Light = Green Wait 20 sec movlw 0x01; movwf PORTB PORTB = YELLOW; Wait(5); PORTB = RED; Wait(20); Light = Yellow Wait 5 sec goto Loop end Light = Red Wait 20 sec

5 5) Software: Write the assembler code which corresponds to the following flow chart: If RB1 (PortB pin 1) is pressed, N is increased by one, stopping at 255. If RB0 (PortB pin 0) is pressed, N is decreased by one, stopping at zero. Assume N is an 8-bit number. Assembler 11 lines of assembler C 20 Lines of Assembler // global variables unsigned char N; Start Start: void Prob5(void) btfss PORTB,1 goto B4 if (RB1) if (N < 255) N += 1; RB1 = 1? if (RB0) cpfseq N if (N > 0) N -= 1; N = 255? incf N,F N = N + 1 B4: btfss PORTB,0 goto B7 RB0 = 1? movlw 0 cpfseq N N = 0? decf N,F N = N - 1 B7: return Return
