Guys,

I made my own development board with STM32F103VCT6, My question is, How can I use PA11 and PA12 as USB connection ? and how to modify the code from ST, Mass_storage application, so it can be used for my board ? Please have a look from the screen shot :

I want to use this library :

Thank you null

Does your camera have a macro mode? Might help with the close-up work.

Suggest you review the

http://www.st.com/st-web-ui/static/active/en/resource/technical/document/user_manual/DM00039084.pdf

for the STM32F4-Discovery board, or one of the others, which use a USB connected STM32F103 to provide ST-LINK support. This is a pretty minimal USB implementation. I don't know much about your board, the changes you'd need to make to the example code would depend a lot on how different it is to the EVAL series boards instantiated in the Utilities directory.
