Working version
This version of the FlashFileSystem is directly derived from a library of the same name by Adam Green. See Adam's original at Flash File System.
Important in the use of this library is the generation of the embedded resource. For this there is a companion tool - rofs.exe. Adam provided a link to the source in github. I used that but found I wanted a few more features, so I made a large number of changes.
ROFS.exe Features
- Bidirectional:
- Create flash file system from folder of resources
- Extract resources from flash file system [.h/.bin]
- w/reduced warnings
- faster file system building
- more internal documentation in the generated .h file
- additional help information added
Windows EXE
- Contact me by Private Email for a copy - the mbed site is not letting me upload it as a zip.
