28-PIN LIN DEMO BOARD

USER’S GUIDE

Chapter 1. 28-Pin LIN Demo Board Overview

1.1 INTRODUCTION

The 28-Pin LIN Demo Board is a small and simple demonstration PCB for Microchip’s

28-pin Dual Inline Package (DIP) PIC

Microcontroller Units (MCU). It is populated with

a PIC16F886 MCU, a MCP2021 LIN Transceiver with voltage regulator, four LEDs, 2

push buttons and a potentiometer. The demo board has several test points to access

the I/O pins of the MCU and a generous prototyping area. The MCU can be

programmed with the PICkit™ 2 Microcontroller Programmer or the MPLAB

ICD 2

using the RJ-11 to 6-pin inline adapter (AC164110).

This chapter discusses:

• 28-Pin LIN Demo Board Supported Devices

• The 28-Pin LIN Demo Board Overview

• Running the Default Demonstration

1.3 28-PIN LIN DEMO BOARD SUPPORTED DEVICES

The 28-Pin LIN Demo Board can be used with virtually any 28-pin Dual Inline Package

(DIP) PIC MCU. The assembled 28-Pin LIN Demo Board is populated with a

PIC16F886-I/P microcontroller.

Additional 28-Pin LIN Demo Boards can be ordered from Microchip Technology and

distributors. Part number, DM164120-3, comes with one assembled and two blank

28-Pin LIN Demo Boards. The blank demo board can be used for evaluating or proto-

typing circuits using any of the 28-pin devices listed below.

28-Pin LIN Demo Board Overview

1.4 28-PIN LIN DEMO BOARD OVERVIEW

The 28-Pin LIN Demo Board is populated with a PIC16F886 MCU (U1), a MCP2021

LIN Transceiver with Voltage Regulator (U2), four LEDs (DS1-DS4), Two push buttons

(SW1 and SW2), 32 KHz crystal (X2) and potentiometer (RP1). The board layout is

shown in Figure 1-1. The demo board has several test points to access the I/O pins of

the MCU and a generous prototyping area. The MCU can be programmed with the

PICkit™ 2 Microcontroller Programmer from header P1.

1.5 RUNNING THE DEFAULT DEMONSTRATION

The assembled 28-Pin LIN Demo Board comes preprogrammed with a demonstration

program. To use this program, power the demo board (9.0-18.0 V

DC) using a LIN

Network Analyzer and/or a bench power supply connected to header P3 or P4. To use

the PICkit™ 2 Microcontroller Programmer, connect it to a PC USB port using the USB

cable. The demo board will blink the LEDs in the Reset pattern. The Reset pattern

consists of three different LED blink patterns. First, the LEDs will “ping pong” (LED1, 2,

3 and 4, then LED 4, 3, 2 and 1). Second, the LEDs will blink on and off in unison. Third,

the LEDs will perform the ADC display where values 0x0A, 0x0D and 0x0C display in

sequence followed by the Most Significant 4 bits of the ADC result measuring channel

1, which is the on-board potentiometer. After this sequence, the EAUSART is initialized

for LIN communcation.

Sending an ID of 0x2F will request a four-byte data response as follows:
