  • Page 11: Introduction

    Thank you for purchasing Microchip Technology’s XLP 8-Bit Development Board. The board provides a low-cost, highly configurable development system for Microchip’s new line of 64 and 80-pin Extreme Low-Power (XLP) microcontrollers, including the PIC16(L)F1947 and PIC18F87K22 families. The XLP 8-bit board permits users to explore and evaluate extreme low-power features, and learn low-power software and hardware techniques.

    AM/PM time. The program permits the user to select between operation modes, each with its own current consumption values. This permits users to experiment with the different Low-Power modes and XLP techniques, as well as make direct measurements. The program flowchart is shown in Figure 2-2.
  • Page 17 LCD is then initialized. The backlight will turn on and the display will begin to show char- acters. The LCD screen should welcome the user with the display “8-Bit XLP Demo Board” for two seconds. The display will then change to show a clock set to 00:00:00.
  • Page 18 Real Time Clock Counter (RTCC) will be initialized, enabling and using Timer1, which keeps count of time using the on-board 32 kHz oscillator crystal. The screen will display the main menu for two seconds. The program is now at the “8-Bit XLP Main Menu”.
  • Page 19 To escape Active mode the user has the option to press RB1 (Select) at any time. The user also has the option to escape Active mode if the alarm is enabled and the specified time is met. Upon exiting, the user will return to the “8-Bit XLP Main Menu”. FIGURE 2-4: ACTIVE DISPLAY A –...
