I am currently working on developing a ultra low cost pick & place solution that requires basic vision such as template matching (rectangular outlines, to determine size, center point and rotation angle). I am currently planning to use a 1.3MP CMOS sensor (like the OV9640) and the STM32F407 (or the STM32F429 for higher speed). How far have you progressed with the template matching code on your project ? I look forward to hearing back from you.<br /><br />Regards,<br /><br />Raj<br />Rajhttps://www.blogger.com/profile/15936868197746417416noreply@blogger.comtag:blogger.com,1999:blog-7822883683244244182.post-11998553377166361942014-01-17T03:19:17.518+02:002014-01-17T03:19:17.518+02:00You probably already have this sorted but I saw th...You probably already have this sorted but I saw this post on DMA and eth 407 Camera interface:<br />http://blog.frankvh.com/2011/08/19/stm32f2xx-digital-camera-interface-dcmi/<br />In case its useful.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-7822883683244244182.post-62225840288671892042013-12-14T21:02:58.348+02:002013-12-14T21:02:58.348+02:00No not yet, I'm still waiting for the boards, ...No not yet, I'm still waiting for the boards, but you should definitely order the new one, it hasn't changed much, so everything should still be working :) muxhttps://www.blogger.com/profile/07901500843676691342noreply@blogger.comtag:blogger.com,1999:blog-7822883683244244182.post-87908737839701891662013-12-14T20:50:41.953+02:002013-12-14T20:50:41.953+02:00Sweet!

The main thing is that it costs nothing extra on PCB ("just" a time which not everybody has :) ) to breakout the most interesting unused GPIOs to small testpoints. I guess that if someone would like to use only your camera module and no ten times slower arduino then your board will be the winner.<br />Just like the metRo_ in the comment above talked about I2C2 and SPI2. I would imagine that SPI2 would be great for connection to some cheap Nokia SPI LCD.<br />Anyway, your project is really great and you've done lot of work.

I do that for all my mcu pcbs. Its better to solder to testpoints than the lqfp pins directly. It would add some value to your board because it will be more hackable.
