 ==Adding Tslib (Touchscreen library) support to SDL==
 SDL is by default compiled with Tslib support in current Buildroot distribution. You just have to make SDL knows the presence of Tslib when launching your  application (assuming you have correct [[Tslib | Tslib envt variables]] set):
   export SDL_MOUSEDRV=TSLIB
   export SDL_MOUSEDEV=$TSLIB_TSDEVICE
- export SDL_NOMOUSE=1
