The IGEP expansion boards (except IGEP New York) provides an AT24C01B serial EEPROM memory which is connected to the OMAP via I2C (register 50).<br>

<section begin=play />

Use i2c-tools to manage it:

<pre>i2cget &lt;bus&gt; &lt;chip&gt; &lt;register&gt;

i2cset &lt;bus&gt; &lt;chip&gt; &lt;register&gt; &lt;value&gt;</pre>

For example, the <section end=play />==IGEPv2 Expansion==<section begin=igepv2exp />The following writes the value 0x22 to register 0x10 of device 0x50 on i2c bus 2:

<pre>i2cset -f -y 2 0x50 0x10 0x22

i2cget -f -y 2 0x50 0x10</pre><section end=igepv2exp /> ==IGEP PARIS Expansion==<section begin=paris />The following writes the value 0x22 to register 0x10 of device 0x51 on i2c bus 3: <pre>i2cset -f -y 3 0x51 0x10 0x22i2cget -f -y 3 0x51 0x10</pre><section end=paris /> ==IGEP BERLIN Expansion==<section begin=berlin />The following writes the value 0x22 to register 0x10 of device 0x51 on i2c bus 3: <pre>i2cset -f -y 3 0x51 0x10 0x22i2cget -f -y 3 0x51 0x10</pre><section end=berlin />
