== How to use TFT and Touchscreen ==
[[Image:berlin_paris_screen_connectors.JPG|right|200px]] IGEP BERLIN Expansion supports SEIKO 7” LCD screen. Use J200, J203 and J204 connectors to attach screen. See image for more details.
By default, Seiko screen is supported in IGEP BERLIN. However open igep.ini, you can do this [[How_do_I_edit_my_kernel_command_line | checking following kernel cmdline parameter]]:
<pre>omapdss.def_disp=lcd-70</pre><br><br>
Finally, edit file: (rootfs)/etc/X11/xorg.conf to enable default touchscreen calibration, xorg.conf touchscreen and ServerLayout sections should look like this:
<pre>Section "InputDevice"
Identifier "Seiko Touchscreen"
Driver "evdev"
Option "Device" "/dev/input/touchscreen0"
# Option "Calibration" "138 3923 311 3962"
EndSection </pre>
<pre>Section "ServerLayout"
Identifier "Builtin Default Layout"
Screen "Builtin Default fbdev Screen 0"
InputDevice "Seiko Touchscreen"
Option "BlankTime" "0"
Option "StandbyTime" "0"
Option "SuspendTime" "0"
Option "OffTime" "0"
EndSection</pre>
 
== How to use DVI ==
[[Image:Berlin hdmi.png|right|200px]] IGEP BERLIN has a '''HDMI connector''' with a '''DVI-D interface'''. IGEP Firmware configures video output with touch screen resolution. For that this reason, you should change this configuration parameter it to adapt resolution for HDMI outputstandard resolution, you can [[How_do_I_edit_my_kernel_command_line | edit following kernel cmdline parameter]].

== How to Telit Modem ==

Configure this [[How_do_I_edit_my_kernel_command_line | adding following kernel cmdline parameter]]
buddy.modem=yes
*Power up the modem using the next commands:
 
<pre>echo 0 &gt; /sys/class/gpio/gpio145/value
echo 1 &gt; /sys/class/gpio/gpio163/value
sleep 1
echo 0 &gt; /sys/class/gpio/gpio163/value</pre>  
*Once the modem is on (led near power button 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>
== How to use to use TVP5151 Video Decoder ==
{{Message/Information Message|title=|message=IGEP COM MODULE AND IGEP BERLIN doesn't support video decoder}}
[[Image:Berlin rca.jpg|right|200px]]IGEP BERLIN Expansion integrates two composite video connectors to decode analog input signal.
=== Configure TVP5151 ===

== How to use EEPROM ==
'''Basic''' IGEP BERLIN Expansion includes a serial EEPROM, provides 1KB of user data storage. EEPROM is connected through I2C2 of OMAP3 processor at address 0x50. {{#lstThe following example writes the value 0x22 to register 0x10 of device 0x50 on i2c bus 3:How to use EEPROM|berlin}}'''Know more''' {{#lst:How to use EEPROM|know_more}} $ i2cset -f -y 3 0x51 0x10 0x22 $ i2cget -f -y 3 0x51 0x10 
''From [[How to use EEPROM]]''
== How to use CAN Bus ==
[[Image:Berlin can.png|right|200px]]IGEP BERLIN Expansion integrates a CAN peripheral. Connect any CAN bus device or network to the CAN bus connector (J901).
 
You have to connect the two boards like this:<br>
IGEP BERLIN 1 IGEP BERLIN 2
.--- .---
| 1 |------------------| 1 | CANH : CAN High-Level Voltage I/O | 2 |------------------| 2 | CANL: CAN Low-Level Voltage I/O | 3 |------------------| 3 | GND : Ground
| 4 |-X X-| 4 |
| 5 |-X X-| 5 |
Now you can set up the interface (on all boards when using multiple IGEP BERLIN <span lang="en" id="result_box" class="short_text"><span title="Click for alternate translations" class="hps">connected to a CAN network simultaneously)</span></span>:<br>
/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:
== How to use serial console ==
Once you connect DV9 [[Image:Berlin db9.png|right|200px]]Connect a DB9 cable between IGEP BERLIN PARIS and Host PC. Open the serial on your PC using your preferred serial communications program (minicom) and configure the port as follows:
* 115200
Open the serial port and the debug shell prompt should appear.
 
A detailed guide on how to connect via serial debug port can be found by following this link: [[Using serial debug port to communicate]]
== How to use RS-485 ==
'''under construction'''{{#lst:How to use RS485|overview}}A detailed guide on how use UARTS can be found by following this link: [[How to use RS485]]
== Get sound in (audio in) ==
External Audio input devices, such as a powered microphone or the audio output of a PC or MP3 player, can be connected to the via a 3.5mm jack (Audio IN).
Note that the board has been designed to use Line In for the audio input which means users need to add some type of pre-amp for a microphone to work or use a powered microphone. For a pre-amp for a microphone you can use MAX9812. Enable capture:  $ amixer -c 0 sset 'Analog Right AUXR' cap $ amixer -c 0 sset 'Analog Left AUXL' cap You can record audio in with the application arecord, for [http://www-mmsp.ece.mcgill.ca/Documents/AudioFormats/WAVE/Samples/AFsp/M1F1-int32WE-AFsp.wav example]:
$ arecord -t wav -c 2 -r 44100 -f S16_LE -v audio-in.wav
$ aplay audio-in.wav
{{Template== How to use the USB OTG ==[[Image:Berlin usbs.png|right|200px]]In order to act in host mode and add some peripherals like keyboard, mouse or pendrives you require a special cable that grounds the ID pin. Since the OTG port only provides 100mA of power a USB hub is recommended. Though a common USB Standard-A to Mini-B type cable the port acts as a device. In this mode you can connect to the board using the USB Ethernet Gadget. Use this cable between your computer and the target board and connect with:  $ ssh root@192.168.7.1 A detailed guide on how use wifi can be found by following this link: [[Using USB ethernet gadget to communicate]] == How to read analog values (ADC) == IGEP BERLIN provides 2 analog inputs on J1206: Maximum allowed analog voltage is 1V8. [[Image:BASE_BERLIN_CONNECTORS.png|right|300px]] To protect the ADC input for higher voltages than 1V8, exist a diode protection (Z300). See diagram on the right side. [[Image:BERLIN_ADC_SCHEMA.png|right|300px]] To prove the lectures, you have examples codes written in phyton in the ISEE GIT. [http://git.isee.biz/?p=pub/scm/igep_qa.git;a=blob_plain;f=igep_qa/helpers/madc.py;hb=HEAD Downlaod Python example] [http:Navigation/IGEP Technology Guides/What can I dogit.isee.biz/?p=pub/scm/Ending}} {{Tableigep_qa.git;a=tree;f=igep_qa/IGEP Technology Deviceshelpers;h=e0671966af9f539bdd7628e101c181d8e74dc506;hb=HEAD ->Link to GIT directory] To read the ADC2 or ADC3 you have to modify one line of code at end of document for the channel 2 or 3. |Tech_Family madc = QMadc(2) or madc ={{#lstQMadc(3) You have another example written in c. [[File:TemplateBERLIN_ADC.tar.gz]]  Warning:Links|IGEP_BERLIN_Tech_Family}}There is a small deviation in reading values near to 1V8 due to this protection.
