How to install Eclipse with IGEP support (under construction)

Overview

Eclipse is a multi-language software development environment comprising an integrated development environment (IDE) and an extensible plug-in system. It is written mostly in Java. It can be used to develop applications in Java and, by means of various plug-ins, other programming languages including Ada, C, C++, COBOL, Haskell, Perl, PHP, Python, R, Ruby (including Ruby on Rails framework), Scala, Clojure, Groovy, Android and Scheme.

Eclipse is very popular among programmers because you can extend its functionalities using plugins. One of these interesting plugins is the Yocto Eclipse IDE Plug-in.

The Yocto Eclipse IDE Plug-in integrates the functionality of the Yocto Project Application Development Toolkit (ADT) and toolchain into the Eclipse IDE. This allows its users direct access to deploy, build, run and debug your own project. More information about Eclipse software here.

What can i do with igepv2 expansion

Overview

This is the 2/3 chapter of IGEPv2 Expansion Tutorial Guide.

We will learn some basic tasks such add support to IGEPv2 Expansion, control some peripherals, etc.

What can I do

How to use Serial communication (DB9 connector)

Basic

RS232 link for UART 3 (/dev/ttyO2) can be obtained through J502 DB9 connector. You can use PuTTy to get a shell prompt to IGEP:

• Power up IGEPv2
• Open PuTTy.
• Choose Serial line. If you are running PuTTy on Windows, the Serial line will be like (COM1 or COM2 or COM3, etc.). If you are running PuTTy on Ubuntu, the Serial line will be like (/dev/ttyS0 or /dev/ttyS1 or /dev/ttyS3, etc.). Note that if you are using a USB->Serial converter, the Serial line will be like /dev/ttyUSB0
• Configure Speed to 115200
• Select Serial Connection type
• Press on Open button
• You will successfully started the console.

Know more

Read this tutorial to learn about UARTs.

How to use TFT and Touchscreen

Seiko a Powertip touch screens are not supported by default in IGEPv2. Use the following steps for it:

• Log into IGEPv2 (via SSH, as shown in the previous chapter), and run the following commands:

ssh root@192.168.5.1 
mkdir /tmp/temp
mount -t jffs2 /dev/mtdblock1 /tmp/temp 
vi /tmp/temp/igep.ini 

• In Seiko screen add the following line:

omapdss.def_disp=lcd-70

• In Powertip screen add the following line:

omapdss.def_disp=lcd-43

• Save changes and reboot your IGEP Device to finish it.
  

How to use Telit Modem

Basic

Telit modem is not supported by default in IGEPv2. Use the following steps for it:

• Log into IGEPv2 (via SSH, as shown in the previous chapter), and run the following commands:

ssh root@192.168.5.1 
mkdir /tmp/temp
mount -t jffs2 /dev/mtdblock1 /tmp/temp 
vi /tmp/temp/igep.ini 

• Add the following line (press i to insert content):

buddy.modem=yes

• Save changes (ESC -> :wq -> Enter) and reboot your IGEP Device
• Power up the modem. You can power off using again these commands:

echo 0 > /sys/class/gpio/gpio140/value
echo 1 > /sys/class/gpio/gpio141/value
sleep 1
echo 0 > /sys/class/gpio/gpio141/value

• Once the modem is on (led D401, near SIM card reader, is blinking now), you can interact with it via UART 2. You can use Microcom to comunicate with it from the serial debug console:

microcom -s 115200 /dev/ttyO1

• To check the modem status use the command:
  

at

• Answer should be OK.
  
• Now unlock it by inserting your SIM card PIN number. Use the command:

at+cpin=<PIN>

• If you correctly inserted the PIN number, the answer should be OK. If you fail more than 3 times, your SIM card will lock and you will have to insert PUK number.
• Now you are ready to use the GSM/GPS modem.
  

Examples

If you successfully followed the the previous instructions, you are ready to test the GSM/GPRS modem. Here are some examples:

You can check the complete list of AT commands at the Official manufacturer Software User Guide.

Test received signal strength

Use the instruction:

at+csq

The answer should be: +CSQ: X,0, where X is the signal strenght. For example 12 is poor and 18 is good. If the answer is +CSQ:99,99 you should check your coverage or use an antenna

Making a phone call

Use the instruction, replace number_to_call with your number:

atd number_to_call

Press any key to end call

NOTE: If "NO CARRIER" message appears, check your coverage or use an antenna.

Sending a SMS

First of all, you need to configure the SMS format type. Telit GE865 GSM/GPRS supports PDU format and Text format. We use Text format. Type the following command:

AT+CMGF=1

There are so many ways in this modem to send a message. Here you have a simple example. Use the instruction, replace destination_number with your number:

at+cmgs= destination_number
> insert here your text message

When you are ready to send your message use Ctrl+Z to send it.

If you want to cancel or restart the message press ESC.

NOTE: If "NO CARRIER" message appears, check your coverage or use an antenna.

NOTE: Don't use special characters in SMS text message like <`´'">.

Know more

Here you have the official manuals from the manufacturer's webpage:

• Telit GE865-QUAD Hardware User Guide
  
• Telit Modules Software User Guide
  

How to use TVP5151 Video Decoder

How to use EEPROM

Basic

The IGEP0022 expansion board provides an AT24C01B serial EEPROM memory which is connected to the OMAP via I2C (register 50).

Use i2c-tools to manage it:

i2cget <bus> <chip> <register>
i2cset <bus> <chip> <register> <value>

For example, the following writes the value 0x22 to register 0x10 of device 0x50 on i2c bus 2:

i2cset -f -y 2 0x50 0x10 0x22
i2cget -f -y 2 0x50 0x10

Know more

See also: i2dump(8), i2cget(8) and i2cset(8) man page

How to use CAN bus (under construction)

You have to connect the two boards like this:

IGEPv2 1             IGEPv2 2
.---                 .---
| 1 |-X            X-| 1 |
| 2 |------------------| 2 | 
| 3 |------------------| 3 |
| 4 |------------------| 4 |
.---                 .---

If this is your first time accessing CAN bus, check J702 jumper is not connected before follow this tutorial. If you don't have this jumper, don't worry because its function is only for testing.

Now you can set up the interface (on all boards when using multiple IGEPv2 EXPANSION connected to a CAN network simultaneously):

/bin/ip link set can0 up type can bitrate 125000

If you want to receive CAN data, use:

candump can0

If you want to send CAN data, use:

cansend can0 -i 0x123 0xaa 0xbb 0xcc 0xdd

On the receiver side, you must see the following messages:

can0  123  [4] aa bb cc dd

Switch roles and try it again
