Detailed Description

This structure is used by the application to define operating parameters for the HID sensor device.

Field Documentation

ui16VID

const uint16_t tUSBDHIDSensorDevice::ui16VID

The vendor ID that this device is to present in the device descriptor.

Referenced by USBDHIDSensorCompositeInit().

ui16PID

const uint16_t tUSBDHIDSensorDevice::ui16PID

The product ID that this device is to present in the device descriptor.

Referenced by USBDHIDSensorCompositeInit().

ui16MaxPowermA

const uint16_t tUSBDHIDSensorDevice::ui16MaxPowermA

The maximum power consumption of the device, expressed in milliamps.

Referenced by USBDHIDSensorCompositeInit().

ui8PwrAttributes

const uint8_t tUSBDHIDSensorDevice::ui8PwrAttributes

Indicates whether the device is self- or bus-powered and whether or not it supports remote wakeup. Valid values are USB_CONF_ATTR_SELF_PWR or USB_CONF_ATTR_BUS_PWR, optionally ORed with USB_CONF_ATTR_RWAKE.

Referenced by USBDHIDSensorCompositeInit().

pfnCallback

const tUSBCallback tUSBDHIDSensorDevice::pfnCallback

A pointer to the callback function which is called to notify the application of general events and those related to reception of Output and Feature reports via the (optional) interrupt OUT endpoint.

Referenced by USBDHIDSensorCompositeInit(), and USBDHIDSensorInit().

pvCBData

void* tUSBDHIDSensorDevice::pvCBData

A client-supplied pointer which is sent as the first parameter in all calls made to the sensor callback, pfnCallback.

ppui8StringDescriptors

const uint8_t* const* tUSBDHIDSensorDevice::ppui8StringDescriptors

A pointer to the string descriptor array for this device. This array must contain the following string descriptor pointers in this order. Language descriptor, Manufacturer name string (language 1), Product name string (language 1), Serial number string (language 1),HID Interface description string (language 1), Configuration description string (language 1).

If supporting more than 1 language, the descriptor block (except for string descriptor 0) must be repeated for each language defined in the language descriptor.

Referenced by USBDHIDSensorCompositeInit(), and USBDHIDSensorInit().

ui32NumStringDescriptors

const uint32_t tUSBDHIDSensorDevice::ui32NumStringDescriptors

The number of descriptors provided in the ppStringDescriptors array. This must be (1 + (5 * (num languages))).

sPrivateData

tUSBDSensorInstance tUSBDHIDSensorDevice::sPrivateData

The private instance data for this device. This memory must remain accessible for as long as the sensor device is in use and must not be modified by any code outside the HID sensor driver.

Referenced by USBDHIDSensorCompositeInit(), USBDHIDSensorInit(), USBDHIDSensorSendReport(), and USBDHIDSensorTerm().
