STM32F4xx Libraries

I wrote a tutorial before on how to setup a toolchain and build the STM32F4xx standard peripheral drivers into one convenient library, since then, a few people have asked me about the library, so to make life easier, I downloaded the latest StdPeriph/CMSIS, in addition to a few other libraries that I might need later, and shared everything in one repository, which currently has the following libraries: Cortex-M...

Color Tracking With OpenMV

So I finally had some free time to work on OpenMV, for those of you who haven't been following this project, OpenMV is an open-source tiny machine vision module based on an STM32F4 ARM Cortex-M4 micro and an OV9650 sensor. I started this project mainly because I find the existing cameras are either too limited for their price or too expensive if they do some image processing, so one of my main goals was to make...
