cjsatuforc / cc1111usb Goto Github PK

welcome to the cc1111usb project

the goals of the project are to reduce the time for security researchers to create needed tools for analyzing unknown targets, to aid in reverse-engineering of hardware, and to satiate my rf lust.

new development efforts should copy the "application.c" file to "appWhateverMyToolIs.c" and attempt to avoid making changes to other files in the repo if at all possible.  that is only a recommendation, because future bug-fixes in other libraries/headers will go must more smoothely for you.

a couple gotchas to keep in mind while developing for the cc1111:
* the memory model includes both "RAM" and "XDATA" concepts, and standard RAM variables and XDATA variables have different assembly instructions that are used to access them.  this means that you may find oddities when using a function written for XDATA on a standard RAM variable, and vice-versa.
* variables should be defined in a single .c file, and then "externs" declared in a .h file that can be included in other modules.  this is pretty standard for c programs, but both this and the previous point caused me difficulties at some points, and i found myself unsure what was causing my troubles.
* RAM memory is not cheap.  use it sparingly.

other than that, hack fun, and feel free to share any details you can about successes and questions about failures you are able!
