}} __TOC__ = Overview = This is the 2/3 chapter of IGEP BERLIN Expansion Tutorial Guide. We will learn some basic tasks. = What can I do === How to use DVI == IGEP Firmware configures video output with touch screen resolution. For that reason, you should change this configuration parameter to adapt resolution for HDMI output, you can [[How_do_I_edit_my_kernel_command_line | edit following kernel cmdline parameter]]. ;omapdss.def_disp=lcd-70 omapfb.mode=dvi:1280x720MR-16@60 == How to Telit Modem ==Telit modem is not supported by default in IGEPv2 Expansion and IGEP Berlin. Configure this [[How_do_I_edit_my_kernel_command_line |Community_MainPageadding following kernel cmdline parameter]] buddy.modem={{#lstyes *Power up the modem using the next commands:<pre>echo 0 > /sys/class/gpio/gpio145/valueecho 1 > /sys/class/gpio/gpio163/valuesleep 1echo 0 > /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:Template<br><pre>at</pre> *Answer should be OK.<br> *Now unlock it by inserting your SIM card PIN number. Use the command:Links|IGEP_BERLIN_Community_MainPage}}|Community_Guides_1<pre>at+cpin=<PIN></pre> *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.<br> ''From [[How to use Telit Modem]]'' == How to use to use TVP5151 Video Decoder =='''under construction''' == How to use EEPROM =='''Basic''' {{#lst:Template:LinksHow to use EEPROM|IGEP_BERLIN_Community_Guides_1berlin}}|Community_Guides_2='''Know more''' {{#lst:Template:LinksHow to use EEPROM|IGEP_BERLIN_Community_Guides_2know_more}}}}''From [[How to use EEPROM]]'' == How to use CAN Bus =='''under construction''' == How to use serial console ==Once you connect DV9 cable between IGEP BERLIN and Host PC. Open the serial on your PC using your preferred serial communications program (minicom) and configure the port as follows: * 115200* 8N1* no flow control (either software or hardware) Open the serial port and the debug shell prompt should appear. == How to use RS-485 =='''under construction''' == 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).
You can record audio in with the application arecord, for example:
Following output is expected on console:
When ever you think you want to stop recording just press CTRL+C
== Get sound out (audio out) ==Connect an external output audio device to the 3.5mm jack Audio Out connector in the board, such as external stereo powered speakers. The amplifiers for the headset output are disabled by default, so the first thing you'll do is enable these amplifiers with: $ amixer set -D hw:0 'Headset' 0dB $ amixer set -D hw:0 'HeadsetL Mixer AudioL2' on $ amixer set -D hw:0 'HeadsetR Mixer AudioR2' on Then you can easily play a *.wav sound with the application Aplay, for example: $ aplay audio-in.wav {{Template:Navigation/IGEP Technology Devices Guides/Next StepWhat can I do/Ending}} {{Table/IGEP Technology Devices|Tech_Family={{#lst:Template:Links|IGEP_BERLIN_Tech_Family}}|Tech_ID={{#lst:Template:Links|IGEP_BERLIN_Tech_ID}}
