Follow
Apache #NuttX RTOS has an NSH Shell that runs simple commands ... Our #LVGL Terminal App shall send commands to NSH over POSIX Pipes

Our #LVGL Terminal shouldn't block while waiting for #NuttX NSH Output ... So we call poll() to check if there's NSH Output ready for processing

Our Terminal App will execute #NuttX NSH Commands on #PinePhone ... With a little help from #LVGL Timers
