struct { | |
USB_Endpoint_Table_t DataINEndpoint | |
USB_Endpoint_Table_t DataOUTEndpoint | |
char * IEEE1284String | |
uint8_t InterfaceNumber | |
} | Config |
struct { | |
volatile bool IsPrinterReset | |
uint8_t PortStatus | |
} | State |
Class state structure. An instance of this structure should be made for each Printer interface within the user application, and passed to each of the Printer class driver functions as the PRNTInterfaceInfo parameter. This stores each Printer interface's configuration and state information.
struct { ... } USB_ClassInfo_PRNT_Device_t::Config |
Config data for the USB class interface within the device. All elements in this section must be set or the interface will fail to enumerate and operate correctly.
USB_Endpoint_Table_t USB_ClassInfo_PRNT_Device_t::DataINEndpoint |
Data IN endpoint configuration table.
USB_Endpoint_Table_t USB_ClassInfo_PRNT_Device_t::DataOUTEndpoint |
Data OUT endpoint configuration table.
char* USB_ClassInfo_PRNT_Device_t::IEEE1284String |
IEEE 1284 identification string, sent to the host during enumeration to identify the printer model, manufacturer and other characteristics.
uint8_t USB_ClassInfo_PRNT_Device_t::InterfaceNumber |
Interface number of the Printer interface within the device.
volatile bool USB_ClassInfo_PRNT_Device_t::IsPrinterReset |
Flag indicating that the host has requested that the Printer interface be reset and that all current Mass Storage operations should immediately abort.
uint8_t USB_ClassInfo_PRNT_Device_t::PortStatus |
Current status of the Printer virtual port, a collection of PRNT_PORTSTATUS_*
bitmask values.
struct { ... } USB_ClassInfo_PRNT_Device_t::State |
State data for the USB class interface within the device. All elements in this section are reset to their defaults when the interface is enumerated.
