EXPLORER 8 DEVELOPMENT BOARD

USER’S GUIDE

Chapter 3. Tutorial Program

The tutorial program is pre-programmed into the PIC16F1719 that comes with the

Explorer 8 demo board. This program, which can be downloaded from the Microchip

web site (www.microchip.com/explorer8), is built using the MPLAB X IDE and the

MPLAB

XC8 Complier. It also utilizes the macros, drivers and initializers generated by

the MPLAB

Code Configurator (MCC). MCC is a plug-in for MPLAB X IDE that

generates seamless, easy to understand drivers and initializers that are inserted into

your project. For more information on MCC, visit www.microchip.com/mcc.

3.1 TUTORIAL PROGRAM OPERATION

The tutorial program consists of three components: Voltmeter, LED Toggle and LED

dimming. The flowchart in Figure 3-1 illustrates the button navigation through the entire

program.

The different components are displayed on the LCD and the LEDs. The data sent to the

LCD is simultaneously transmitted by the EUSART module of the device to the

USB-to-UART/I

C converter and can, therefore, be viewed on the host PC monitor

through a serial terminal program (see

Section 2.4 “Connecting to Host PC for USB

Communication”

). Make sure that the terminal program is configured to 9600 Baud,

8-bit Data, No Parity and 1 Stop Bit. For the board supply and jumper configurations,

see

Section 2.1 “Explorer 8 with Pre-Programmed Device”.
