# Warning : Use this tool at your own risks, nobody can be taken as responsible if it damage your calculator !!!
# Usage
## Usage
The buttons are actually diconnected, if you want to test, dive through the code.
# Things to change
## Things to change
- Have a more js-like code approach !
# Actual possibilities
## Actual possibilities
- You can send files to flash memory (at least fls0, but maybe crd0 too), but only below ~1.5 ko (it freezes beyond, will patch this later)
- You can list files, make directories, remove directories etc...
- you can optimize your flash
- you can get your device infos
# Future possibilities
## Future possibilities
- Make a user friendly interface
- Support all p7 protocol's commands
- Screen casting ? (not a usb but a graphic difficulty)
- other stuffs
# Thanks to :
## Thanks to :
- Simon Lothar for his fx-reverse doc
- Cakeisalie5 for his p7 command line tool
