  • 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.

  • To learn how to program a keypad activated interrupt that identifies the key being pressed and displays or otherwise returns its value to the main program.

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?3. What is the percent error for the binary answer found in Problem #2?

  • 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?
