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.
+
'''Random fatal bit error'''
  
−
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 [http://en.wikipedia.org/wiki/Eclipse_%28software%29 here].

IGEP Firmware Yocto uses the following Ethernet network configuration (IP addresses)

*eth0 − 192.168.5.1

*eth0:0 − assigned via dhcp.

'''Basic''' [[Image:Igepv2expdb9connector.PNG|right|200px]]

This Ethernet network configuration is really useful when you work using a Linux operating system like IGEP SDK Virtual Machine. Because you use eth0 device to communicate easily with your board and eth0:0 device to get Internet acces using dhcp protocol.

IGEPv2 Expansion integrates a DB9 RS232 connector. Plug a DB9 cable. <br>

−
 
 
−
*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&nbsp;(/dev/ttyS0 or /dev/ttyS1 or /dev/ttyS3, etc.). Note that if you are using a USB-&gt;Serial converter, the Serial line will be like /dev/ttyUSB0
 
−
*Configure Speed to 115200
 
−
*Select Serial Connection type
 
−
*Press on Open button

== 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, [http://labs.isee.biz/index.php/Getting_started_with_IGEPv2#Log_into_IGEPv2_via_Ethernet_interface as shown in the previous chapter]), and run the following commands:
 
−
<pre>ssh root@192.168.5.1
 
−
mkdir /tmp/temp
 
−
mount -t jffs2 /dev/mtdblock1 /tmp/temp
 
−
vi /tmp/temp/igep.ini </pre>
 
−
*In Seiko screen add the following line:
 
−
<pre>omapdss.def_disp=lcd-70</pre>
 
−
*In Powertip screen add the following line:
 
−
<pre>omapdss.def_disp=lcd-43</pre>
 
−
*Save changes and reboot your IGEP Device to finish it.<br>

== 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, [http://labs.isee.biz/index.php/Getting_started_with_IGEPv2#Log_into_IGEPv2_via_Ethernet_interface as shown in the previous chapter]), and run the following commands:
 
−
<pre>ssh root@192.168.5.1
 
−
mkdir /tmp/temp
 
−
mount -t jffs2 /dev/mtdblock1 /tmp/temp
 
−
vi /tmp/temp/igep.ini </pre>
 
−
*Add the following line (press i to insert content):
 
−
 
 
−
buddy.modem=yes
 
−
 
 
−
*Save changes (ESC -&gt;&nbsp;:wq -&gt; Enter) and reboot your IGEP Device
 
−
*Power up the modem. You can power off using again these commands:
 
−
<pre>echo 0 &gt; /sys/class/gpio/gpio140/value
 
−
echo 1 &gt; /sys/class/gpio/gpio141/value
 
−
sleep 1
 
−
echo 0 &gt; /sys/class/gpio/gpio141/value
 
−
</pre>
 
−
*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:
 
−
<pre>microcom -s 115200 /dev/ttyO1</pre>
 
−
*To check the modem status use the command:<br>
 
−
<pre>at</pre>
 
−
*Answer should be OK.<br>  
 
−
*Now unlock it by inserting your SIM card PIN number. Use the command:
 
−
<pre>at+cpin=&lt;PIN&gt;</pre>
 
−
*If you correctly inserted the PIN number, the answer should be OK.&nbsp;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.<br>
 
−
 
 
−
=== 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 [http://telit.com/module/infopool/download.php?id=522 Software User Guide].
 
−
 
 
−
==== Test received signal strength<br>  ====
 
−
 
 
−
Use the instruction:
 
−
<pre>at+csq</pre>
 
−
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<br>
 
−
 
 
−
==== Making a phone call<br>  ====
 
−
 
 
−
Use the instruction, replace number_to_call with your number:
 
−
<pre>atd number_to_call
 
−
</pre>
 
−
Press any key to end call
 
−
 
 
−
'''NOTE:''' If "NO CARRIER" message appears, check your coverage or use an antenna.
 
−
 
 
−
==== Sending a SMS<br>  ====
 
−
 
 
−
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:
 
−
<pre>AT+CMGF=1</pre>
 
−
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:
 
−
<pre>at+cmgs= destination_number
 
−
&gt; insert here your text message
 
−
</pre>
 
−
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.<br>
 
−
 
 
−
'''NOTE:''' If "NO CARRIER" message appears, check your coverage or use an antenna.
 
−
 
 
−
'''NOTE:''' Don't use special characters in SMS text message like &lt;`´'"&gt;.<br>

BASE0033 CONNECTOR SUMMARY TABLE

Configure a static IP using the same private network range

under construction

IGEP Firmware Yocto uses the following Ethernet network configuration (IP addresses)

  • eth0 − 192.168.5.1
  • eth0:0 − assigned via dhcp.

This Ethernet network configuration is really useful when you work using a Linux operating system like IGEP SDK Virtual Machine. Because you use eth0 device to communicate easily with your board and eth0:0 device to get Internet acces using dhcp protocol.

But some scenarios this network configuration is not useful, for example: if you use a non-Linux operating system, connect to two IP private range interfaces is not simple. This How-to can be useful to

(Make diagram one: IGEP and Linux defualt communication. Diagram 2 IGEP and other SO alternative configuration)
