MICRIUM USB-USBH-SAM9XX-P-P1-PLATFORM 软件开发工具, UC/USB-HOST CORE, AT91SAM9X, PLAT
is a uC/USB-Host core on the Atmel AT91SAM9x microcontrollers with platform license. uC/USB Host is a real-time USB Host software stack designed for embedded systems equipped with a USB Host or OTG controller. The USB host communicates with the devices using a USB host controller. The host is responsible for detecting and enumerating devices, managing bus access, performing error checking, providing and managing power, and exchanging data with the devices. uC/USB Host uses a modular architecture with three software layers between the application and the hardware.
