I think that we need to modify also IoDrvArduinoUNO.library and the program inside Arduino. Who are able to do so?<br/> Massimo</p></div>

<div class="markdown_content"><p>Do you have the I2C .library and devdesc.xml for Arduino Mega ?</p> <p>I found 24VDC Industrial PLC based on Arduino Mega like <a class="" href="http://controllino.cc/" rel="nofollow">http://controllino.cc/</a></p> <p>I do not know how to build new libraries for I2C, <br/> maybe you have some links just to start writing new library and devdesc.xml or instruction?,<br/> but a kind of I2C with ModBus Write 10words and Read10words should be very useful.</p> <p>Thank you</p></div>
