-TinyUSB is completely thread-safe by pushing all ISR events into a central queue, then process it later in the non-ISR context. It also uses semphore/mutex to access shared resource such as CDC FIFO. Therefore the stack needs to use some of OS's basic APIs. Following OSes are already supported out of the box.

 # Boards
 
 The board support code is only used for self-contained examples and testing. It is not used when TinyUSB is part of a larger project. It is responsible for getting the MCU started and the USB peripheral clocked with minimal of on-board devices
-- One LED for status
-- One Button to get input from user
-- One UART optionally, mostly for host examples
+- One LED : for status
+- One Button : to get input from user
