infrared 3 Posted February 28, 2011 Share Posted February 28, 2011 Seen the chip in a MultiMedia dock for the dual core tegra 2 Moto Atrix. Will give away a launchpad to the first person to publish the code contained on that chip. Quote Link to post Share on other sites
bluehash 1,581 Posted February 28, 2011 Share Posted February 28, 2011 Hmmm.. wow. Infrared, did you personally rip your dock out? Any idea what it controls? maybe power management or docking/undocking procedures. Quote Link to post Share on other sites
infrared 3 Posted February 28, 2011 Author Share Posted February 28, 2011 The Motorola Atrix 4G is the worlds first dual core smartphone running Android OS. The uniqueness of the Atrix is the Docks that can be purchased as accessories. There is a multimedia dock that has an infrared remote control, 3 USB ports and connects to the display via a pass through HDMI cable. The phone has a Ubuntu "webtop" application that starts when plugged into the dock. (there is even a really cool laptop dock that turns the phone into a full laptop) @BlueHash I did not tear one down to find out. A dev @ http://forum.xda-developers.com/showthread.php?t=963938&page=9 specifically this post http://forum.xda-developers.com/showpost.php?p=11658048&postcount=84 tore one down and posted about the IC's inside. Now, I am not going to pay $200 for a dock that has a <$5 TI msp430 in it. So I am building my own with a launchpad. Over at XDA they are trying to get it to work without a dock at all and just an HDMI cable, using scripts and modified config files. I have it working in webtop mode with a modified USB hub. The issue is sending an ID to the Atrix (f5522 must be doing this) to determine the dock type connected to and launching the appropriate application. (for example the car dock differs by not having HDMI so webtop does not get launched, instead the car dock launches a UI specific for operating a car i.e. Nav and music streaming.) Unfortunately, Motorola axed the capability to use the applications without a dock being attached. I assume the f5522 is handling the host mode/peripheral mode of the Atrix USB port so that a mouse/keyboard can be wired (although bluetooth is the recommended way of attaching HID). With the f5522 firmware, I may be able to design my own dock capable of new things. Need to know how the ID pin is pulled low and when the SID is sent to the phone. gatesphere, jsolarski and bluehash 3 Quote Link to post Share on other sites
