Se proporcionan componentes de la pila USB para hosts USB (USB Host) y para dispositivos conectados (USB Device). El c\u00f3digo del proyecto est\u00e1 escrito en C y se distribuye bajo la licencia MIT.    <\/p>\n<p>Para aumentar la seguridad, TinyUSB no utiliza operaciones de asignaci\u00f3n din\u00e1mica de memoria. Se admite su uso en aplicaciones multihilo. Para un funcionamiento seguro en m\u00faltiples hilos, todos los eventos relacionados con la ocurrencia de interrupciones no se procesan inmediatamente al recibir la ISR (Interrupci\u00f3n de Servicio), sino que se colocan en una cola que se procesa en el contexto de ejecuci\u00f3n de la aplicaci\u00f3n, y no en el controlador de interrupciones. Al acceder a recursos compartidos, como FIFO CDC (Clase de Dispositivos de Comunicaci\u00f3n), se utilizan sem\u00e1foros y mutexes.     <\/p>\n<p>La pila est\u00e1 abstra\u00edda del sistema operativo y puede utilizarse como un componente independiente, no vinculado a la funcionalidad de sistemas operativos. No obstante, hay m\u00f3dulos disponibles para integrar TinyUSB con FreeRTOS, RT-Thread y Apache Mynewt. Se admiten caracter\u00edsticas de reducci\u00f3n de consumo de energ\u00eda, como el modo de suspensi\u00f3n y el despertador con la aparici\u00f3n de actividad. Hay una implementaci\u00f3n inicial del protocolo PD 3.0 (Power Delivery) para gestionar la transferencia de energ\u00eda a trav\u00e9s de USB Type-C.       <center><img decoding=\"async\" alt=\"Se ha publicado la pila USB de c\u00f3digo abierto TinyUSB 0.19\" src=\"\/wp-content\/uploads\/2025\/10\/77b99418cff48336d22a2162c453e404.png\" style=\"display:block;margin: 0 auto;\" \/><\/center>    <\/p>\n<p>TinyUSB permite a\u00f1adir soporte para clases de dispositivos USB y hosts personalizados sin modificar la pila USB.
