Overview

This is the 1/3 chapter of IGEPv2 Expansion Tutorial Guide.

In this first chapter, we will learn how to connect some expansion peripherals.

Requirements

In these tutorials we are going to need the following components :

• IGEPv2, +5V DC power supply, Ethernet cable and a PC with Linux or Windows.
  
• Powertrip 4.3" or Seiko 7" screen if you need a touch screen.
• DB9 connector and USB serial converter to follow serial communication tutorial
  
• 4 pin connector for CAN Bus with another IGEPv2 and Expansion to follow CAN Bus communication tutorial
  
• SIM card with an antenna to follow Telit modem tutorial
  
• Composite video cable, composite video output peripheral (PAL or NTSC) and a screen to follow TVP5151 tutorial
  

Getting started

Connect IGEPv2 Expansion with IGEPv2 Board

Basic

The IGEPv2 Expansion connects to the IGEPv2 Board through J990, JA41, JA42, JC30 and J960 connectors. Some IGEPv2 Expansion may include three jumpers, you should remove it because they are designed for test and lab purposes. Just take a look on the figure below to mount it:

Serial port

Basic

IGEPv2 Expansion integrates a DB9 RS232 connector. Plug a DB9 cable.

Know more

This peripheral (UART 3) can be used to debug system using kernel traces, getting a remote prompt, etc.

VGA monitor

Basic 

IGEPv2 Expansion integrates a VGA connector, the output VGA signal is equal to HDMI connector. Plug a monitor with VGA input.

Know more

This output is controled by ADV7125KSTZ140 Integrated Circuit.

CAN bus

Basic

IGEPv2 Expansion integrates a CAN peripheral. Connect any CAN bus device or network to the CAN bus connector (J703).

Know more

This output is controled by MICROCHIP MCP2515. J703 is a 3.5 mm pitch terminal blocks 4 Positions:

Signal Name	Pin #	Description
VDD_CAN	J703:1	Supply Voltage (+5V DC)
CANL	J703:2	CAN Low-Level Voltage I/O
GND	J703:3	Ground
CANH	J703:4	CAN High-Level Voltage I/O

GSM/GPRS modem

Basic

GSM-GPRS antenna (highly recommended)	SIM card reader

IGEPv2 Expansion integrates a GSM/GPRS modem to make phone calls or to send SMS or to write and read data from it, etc.

Know more

Modem chip Telit GE865 is a small GSM/GPRS Ball-Grid-Array BGA module with next main features:

• Quad-band EGSM 850 / 900 / 1800 / 1900 MHz
• Power consumption (typical values)

    - Power off: ‹ 62 uA
    - Idle (registered, power saving): 1.6 mA @ DRX=9

Composite Video Decoder

Basic

IGEPv2 Expansion integrates two composite video connectors to decode analog input signal. Plug some peripheral with video composite output.

Know more

Analog input is decoded by TVP5151.
