STM32F429-DISCO+OV7670 MAC and Linux project with arm-none-eabi-gcc, it is modified from Individální projekty MPOA Keil-C project.
I use the same parameters of OV7670 as STM32F429, but the color will be wrong in my design, maybe the problem is exposure, gain, high-speed clock-signal layout? that is my issue list. to be fix.
