Have finished the layout and about to send the board to fabrication.</p> <p>I have shared pictures of 3d model, schematics, cost etc at sparkfun thread.<br /> <a href="http://forum.sparkfun.com/viewtopic.php?f=14&amp;t=32645" rel="nofollow">http://forum.sparkfun.com/viewtopic.php?f=14&amp;t=32645</a></p> <p>Soon will start work on software, will be back with tons of questions. In fact I have a question right now. Where can I get Maple code base that works with STM32F4. I understand that the code base is probably still under development.</p> <p>Cheers<br /> brijesh </p> http://forums.leaflabs.com/topic.php?id=1885#post-11214 Mon, 11 Jun 2012 14:09:12 +0000 mbolivar 11214@http://forums.leaflabs.com/ <blockquote><p> I have not looked at the maplelib yet, do you have code there for DCMI peripheral?</p> </blockquote> <p>No, there isn't DCMI support right now. <a href="http://leaflabs.com/docs/libmaple/contributing.html">Patches welcome</a>. </p> http://forums.leaflabs.com/topic.php?id=1885#post-11211 Mon, 11 Jun 2012 13:41:01 +0000 brijesh 11211@http://forums.leaflabs.com/ <p>mbolivar,</p> <p>I have not looked at the maplelib yet, do you have code there for DCMI peripheral?</p> <p>Thanks </p> http://forums.leaflabs.com/topic.php?id=1885#post-11210 Mon, 11 Jun 2012 13:39:27 +0000 brijesh 11210@http://forums.leaflabs.com/ <p>Hello Thomas,</p> <p>I did look at Olimex board. I contacted them asked if they had datasheet for the camera module and they said they don't have it.<br /> Also the form factor is not conducive for small robot. So developing this new board. </p> http://forums.leaflabs.com/topic.php?id=1885#post-11208 Mon, 11 Jun 2012 12:33:51 +0000 mbolivar 11208@http://forums.leaflabs.com/ <blockquote><p> I do not see any specific interface for a Camera module.

We've used the DCMI peripheral, and it's nice, but the high pin count on the chips that fully support it means DCMI support won't be part of the initial Maple II release. </p> http://forums.leaflabs.com/topic.php?id=1885#post-11194 Sun, 10 Jun 2012 04:05:48 +0000 ThomasB 11194@http://forums.leaflabs.com/ <p>Hi Cheers,</p> <p>Interesting Project!<br /> Do you know the STM32-P407 board from olimex?<br /> Not very compact, because it's more a 'All-In what's thinkable' board<br /> but it includes a STM32F4 and a onboard camera module, so maybe interesting for you.<br /> Here the link to the schematic: <a href="http://www.olimex.com/dev/ARM/ST/STM32-P207/STM32-P207-SCHEMATIC-REV-A.pdf" rel="nofollow">http://www.olimex.com/dev/ARM/ST/STM32-P207/STM32-P207-SCHEMATIC-REV-A.pdf</a></p> <p>best</p> <p> Thomas </p> http://forums.leaflabs.com/topic.php?id=1885#post-11179 Fri, 08 Jun 2012 19:48:30 +0000 brijesh 11179@http://forums.leaflabs.com/ <p>Hello,</p> <p>I just came to know that you guys are developing next version of Maple using STM32F4 device. I saw the schematics posted in one of the forum posts. I do not see any specific interface for a Camera module. I guess you are not planning on camera interface as of now?</p> <p>I just started to work on a project to build low cost vision module using STM32F4. I put together my idea in a few slides which you can see at</p> <p><a href="https://docs.google.com/presentation/d/1gqUJGU0NmZUGGmHDdDbCDIJePcvL9S4tyn_3nyUN_LA/edit" rel="nofollow">https://docs.google.com/presentation/d/1gqUJGU0NmZUGGmHDdDbCDIJePcvL9S4tyn_3nyUN_LA/edit</a></p> <p>Also a discussion at Sparkfun forum.<br /> <a href="http://forum.sparkfun.com/viewtopic.php?f=14&amp;t=32645" rel="nofollow">http://forum.sparkfun.com/viewtopic.php?f=14&amp;t=32645</a></p> <p>This project is still at initial stage, I am working on the schematics. It would be a good idea to use Maple IDE and maplelib. In that regard are there any specific hardware requirements for IDE and madplelib?</p> <p>My design currently is very minimal, not even using external crystal oscillator. I want to keep the design very simple so that I can get the first prototype out quickly and at low cost.</p> <p>Appreciate your thoughts and feedback.</p> <p>Cheers<br /> brijesh </p>
