Is there an easy howto on writing C++ app for Samsung Smart TV that should be able to run in background (so not an HTML/JS applet) and access /dev/ttyUSBx device plugged in the TV?
Do they have some API to access /dev/ttyUSBx or it will be a simple Linux app? Do they allow to load such apps? Is there a toolchain to compile such apps?
At least according to Samsung, "No."
Q: Do you support C++ in the SDK?
A: No, Samsung platform only supports web technologies based apps (JS, CSS, HTML, FLASH)
