Host Class Driver Selection
This section explains the configuration options for the USB Host Class Driver layer. The options are set in the file usb_config.c.
The Class Configuration options enable the host to interact with the following device types:
Mass Storage Device Class (MSC)
Mass Storage Device Class (MSC) activates the host support for accessing mass storage devices. This option corresponds to the first bit of #define USBH_CLASS.
#define USBH_CLASS 0x0001 // MSC enabled
-
Number of concurrent MSC Devices on a single USB Host controller specifies maximum number of instances of mass storage device class per USB Host controller. This option corresponds to the value of #define USBH_MSC_NUM.
#define USBH_MSC_NUM 1
Human Interface Device Class (HID)
Human Interface Device Class (HID) activates the host support for accessing HID devices. This option corresponds to the second bit of #define USBH_CLASS.
#define USBH_CLASS 0x0002 // HID enabled
-
Number of concurrent HID Devices on a single USB Host controller specifies maximum number of instances of human interface device class per USB Host controller. This option corresponds to the value of #define USBH_HID_NUM.
#define USBH_HID_NUM 1
USB Device Class (custom, vendor or additional class)
USB Device Class activates the host support for custom, vendor or additional class devices. It allows adding support for classes other than MSC or HID. This option corresponds to the third bit of #define USBH_CLASS.
#define USBH_CLASS 0x0004 // USB device enabled
-
Number of concurrent Custom Class Devices on a single USB Host controller specifies maximum number of instances of custom device class per USB Host controller. This option corresponds to the value of #define USBH_CLS_NUM.
#define USBH_CLS_NUM 1
