2.3 Function
USB-BASIC-FW source code includes files for Host, Peripheral (Function) and common code.
[Common code]
・ Device connect/disconnect, suspend/resume, and USB bus reset processing
・ Control transfer on pipe 0
・ Data transfer on pipes 1 to 9 (bulk or interrupt transfer: CPU access/DTC or DMA access)
[Host]
・ In host mode, enumeration as low-speed/full-speed/high-speed device (However, operating speed is different by
devices ability.)
・ Transfer error determination and transfer retry
[Peripheral ]
・ In peripheral mode, enumeration as USB Host of USB1.1/2.0/3.0.
2.4 Structure of Files and folders
2.4.1 Folder Structure
The folder structure in which the files are provided in USB-BASIC-FW (non-OS & RTOS) is shown below. The USB-
BASIC-F/W includes a sample (vendor) class driver, application and hardware resource sample code.
The source codes dependent on each device and evaluation board are stored in each hardware resource folder
(HwResourceForUSB_devicename).
