USB Support- The camera now supports USB OTG full speed, I’ve also written a small userspace tool with libusb/SDL to interface with the camera and view the frame buffer, this makes it really easy to debug the image processing code, and it also lets you change the sensor’s registers while watching the results in realtime.
I’ve mentioned building the STM32F4xx libraries in a previous post, you can checkout the repo linked there if you want to build the libraries.
Face Detection-Many were very interested in this feature, well I’ve managed to get the viola-jones face detector working on the camera, and it’s working fine…
