28-PIN LIN DEMO BOARD USER’S GUIDE © 2009 Microchip Technology Inc. DSxxxxx Note the following details of the code protection feature on Microchip devices: • Microchip products meet the specification contained in their particular Microchip Data Sheet. • Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the intended manner and under normal conditions. • There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data Sheets. Most likely, the person doing so is engaged in theft of intellectual property. • Microchip is willing to work with the customer who is concerned about the integrity of their code. • Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not mean that we are guaranteeing the product as “unbreakable.” Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our products.

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). 1.2 HIGHLIGHTS 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 prototyping circuits using any of the 28-pin devices listed below.

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. FIGURE 1-1: 28-PIN LIN DEMO BOARD PICkit™ 2 or 3 Programming Header Aux Power Connector Crystal Mounting Pads LIN Analyzer Connectors 32 KHz Crystal GND LIN +9-18V Push Button SW2 Generous Prototyping Area Push Button SW1 Potentiometer RP1 LEDs DS1-DS4 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 VDC) 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: Data byte 1 = ADC result © 2009 Microchip Technology Inc.
