  2. ECET 340 (Devry) ASH Course Tutorial ECET 340 Entire Course (All ilabs and Homework) (Devry) ECET 340 Week 1 HomeWork 1 (Devry) • ECET 340 Week 1 HomeWork 1 • ECET 340 Week 1 iLab 1 • ECET 340 Week 2 HomeWork 2 • ECET 340 Week 2 iLab 2 • ECET 340 Week 3 HomeWork 3 • ECET 340 Week 3 iLab 3 • ECET 340 Week 4 HomeWork 4 • ECET 340 Week 4 iLab 4 • 1. Give three examples each of internal and external peripheral devices as referenced to the HCS12 microcontroller and not an entire PC. (2 points)

  3. ECET 340 (Devry) ASH Course Tutorial ECET 340 Week 1 iLab 1 (Devry) ECET 340 Week 2 HomeWork 2 (Devry) • OBJECTIVES: • To become familiar with Microcontroller MC9S12 parallel ports and how simple input and output devices are interfaced through them. • To learn how to program I/O instructions in C language. • 1. Where does program control transfer to when an interrupt occurs? +2 points • 2. Which one of the following Interrupts has highest priority? +2 points • 3. RAM Vector table addresses $3E52 belongs to which interrupt? +2 points

Sketch a circuit that can be used to debounce a pushbutton and explain how it works. (4 points max) • 2. In Figure 7.32 on page 339 of the Huang textbook, if the row has and the columnsare , which key is pressed? (2 points max)

  5. ECET 340 (Devry) ASH Course Tutorial ECET 340 Week 3 iLab 3 (Devry) ECET 340 Week 4 HomeWork 4 (Devry) • SOLVED ECET 340 iLAB3 • OBJECTIVES: • To learn the basic operation of a keypad. • To understand how to interface a keypad to a microprocessor. • To learn how to program a keypad driver in C language. • 1. Determine the conversion time for an ADC0804 (8-bit), where 66 clocks per bit are required, if its clock frequency is 50 kHz.2. If an 8-bit SAR has Vref = 10 V, what is the binary value for an input voltage of 7.28 V?

  6. ECET 340 (Devry) ASH Course Tutorial ECET 340 Week 4 iLab 4 (Devry) ECET 340 Week 5 HomeWork 5 (Devry) • I. OBJECTIVES: • To learn how to use A-to-D converters to digitize signals from analog input devices. • To learn how to write a C language program that samples the data from an analog device, digitizes it and formats it for output on an LCD. • 1. Explain, briefly, why an analog restoring filter is sometimes used at the output of a DAC.2. Given Iref = 2 mA for a DAC1408 IC, find Iout for the input 1110 1110

  7. ECET 340 (Devry) ASH Course Tutorial ECET 340 Week 5 iLab 5 (Devry) ECET 340 Week 6 HomeWork 6 (Devry) • Scenario/Summary • This week's lab covers two areas, conversion of digital HCS12  • signals to an analog format, and the use of a Serial Peripheral Interface (SPI)  • to transfer data, and commands between the HCS12, and the DAC  • peripheral.  • 1. What are the four main functions of the HC12 Timer unit?2. Two input capture events occur at counts 0x1037 and 0xFF20 of the free-running counter. How many counts (in decimal) have transpired between these two events?3. What is the maximum time possible before the free-running counter overflows when the e MHz?
