This Howgst-To is meant to be a starting point for people to learn use SPI for IGEP devices as quickly and easily as possible. In this howlaunch --gst-to, we run an example program that reads and writes registers from 3debug-axis accelerometer ([http://www.st.com/internet/analog/product/250725level=2 filesrc location=Canon.jsp LIS3DH]) included on the board IGEP New Yorkmp3 !

== Prepare Micro SD Card =='''does not have an accelerated audio decoder element'''
=== Generate Micro SD Card ===- Compiled gst-plugins-ugly using yocto tools
Open a terminal and use the following steps to download and generate a Micro SD card. <pre>wget http://downloads.isee.biz/denzil/binary/igep_firmware-yoctorpm -1.2.1igst-1.tar.bz2 tar jxf igep_firmwareplugins-yoctougly-*.tar0.bz2cd igep_firmware-yocto-* </pre> Insert a SD-Card media and use the igep-media-create script to copy the firmware. rpm
./igep-media-create -–mmc <mmc> --image demo-imagerpm -satoi libmad0-igep00x00.tar*.bz2 --machine igep0030 rpm
where <mmc> - is the SD-Card device of your computer. For example, assuming the SD-card device takes '/dev/sdb' type: <pre>./igep-media-create --mmc /dev/sdb --machine igep0030 rpm -i gst-image demoplugins-imageugly-satomad-igep00x00.tar.bz2 </pre> This should give you a bootable SD-card with IGEP COM MODULE support*. rpm

} IGEP Firmware Yocto uses the following Ethernet network configuration (IP addresses)
void __init ilms0015_init(void) 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
mux_partition = omap_mux_get("core"Make diagram one: IGEP and Linux defualt communication. Diagram 2 IGEP and other SO alternative configuration);
/* Mux initialitzation for ilms0015 */ = igep.ini parameters =
omap_mux_write_array(mux_partition, ilms0015_mux); The kernel command line syntax is name=value1. These next parameters are supported in igep.ini since IGEP-X_Loader 2.4.0-2:
/* 3-axis accelerometer */ ilms0015_lis3lv02d_init(1, 2, 174); /* Export some GPIO */ ilms0015_gpio_init(); } === [kernel] ===
Now spi_register_board_info has all information necessary to attach spidev driver instead lis3lv02d_spi. === [kparams] ===

'''Read mode: '''Reads a word from a register. '''Write mode: '''Writes a word in a register. '''Test mode:''' Reads X, Y and Z axes from accelerometer.
