XLP 8-Bit Development Kit Quick Start Guide

Overview

The XLP 8-Bit Development Board is pre-programmed with a demonstration program. The board
must be connected as described in this document to use the demons tration program. To measure
current consumption, the current analyzer cable must be set up as described in this document.

XLP 8-Bit Development Board Setup

The kit includes the XLP 8 -Bit Develo pmen t Boar d, curren t a nalyzer ca ble, USB conne ctio n cable ,
bag of 15 jumpers, and Microchip's PIC16LF1947 and PIC18F87K22 microcontrollers. To use the
kit, follow the steps below:

1. Insert either the PIC1 6LF 1947 or PIC18F87K22 microcontroll ers onto the XLP 8-bit board.
Make sure you insert the microcontroller as shown in the figure below.

CAUTION

Ensure that the bevel indicators on the PIM and board match up for correct
placement (see figure below). Failure to do so may damage the device.

2. Confirm jumper configurations using the table provided.

3. Connect the current analyzer ca ble to the pins as indicated in this document.

Board Power-Up

Supply pow e r to th e board in one of the following w a ys :

• Connect the USB cable using the J13 connector. [J8 is ON]

• Connect two (2) AAA Batteries to B1 & B2, or a coin battery to B3. [J9 is ON; J12 is USED]

• Connect an external 3.3-S VDC supply to (+VEXT) and (GND). [J10 is ON]

• Connect Microchip's Harvester device to J17. [J11 is ON]

LED D5 will immediately turn on after power-on.

Note: Using the table on the next page, confirm your power source jumper configurations

before supplying power to the board.

Program Layout

XLP 8-Bit Welcome Screen – [2 sec]

• Button Layout – Display button function layout [2 sec]

• Initial Clock Setup – Set up cloc k. Increase hours and minutes; starts in global time.

• Main Menu – [2 Sec] lntroduction screen. Select demonstrat ion mode.

• Settings Menu – [2 Sec] Introduction screen. Select custom settings.

• Active Mode – Run current mode. CPU on; peripherals on.

• With CPU on and peripherals on, the chip is at full strength. In this mode it will
show clock, temperature, frequency, brightness scale and alarm indicator.

• Exit Condition: Select [RB1] or Alarm.

• Conserve Mode – Idle current mode. CPU off; peripherals on.

• With CPU off and peripherals on, the current consumption is minimized while
keeping track of time. Dependent upon settings (wake-up, display length], the
CPU will wake up and enter Active mode for a set amount of time before return­ing to Sleep.

• Exit Condition: Select [RB1] or Alarm.

• Sleep Mode – Sleep current mode . CPU off; peripherals off.

• With CPU off and peripherals off, current consumption is at a minimal. The
device is no longer able to keep track of time. Only outside interrupts will wake it
from Sleep.

• Exit Conditions: Select [RB1]

• Time – Custom time-related settings.

• Set Time – Adjust hours and minutes.

• Time Standard – Select [24 – HR] or [12 – HR] time standar d .

• Set Alarm – Select 30 or 60 minute nap ala rm; set custom time for alarm.

• Alarm Toggle – Enable/Disable alarm.

• Wake-up Interval – Used in conserve mode. Select to wake up every 15, 30 or
50 seconds, or do not wake up.

• Display Length – When woken up, display for 5 or 10 seconds. Disabled if

none.

• Frequency

• 32 kHz – Run at 32 kHz; LFINTOSC

• 500 kHz – Run at 500 kHz; MFINTOSC

• 4 MHz – Run at 4 MHz; HFINTOSC

• 32 MHz – Run at 8 MHz with PLL enabled; HFINTOSC + PLL

• Temperature

• Display Temperature – Display temperature in Celsius or Fahrenheit.

• Temperature St andard – Choose Celsius or Fahrenheit for display.

• LCD

• Backlight Toggle – Enable/Disable LCD backlight.

• Adjust Brightness – Adjust brightness of backlight.

• Save Custom – Save Sett ings to EEPROM.
