Class state structure. An instance of this structure should be made within the user application, and passed to each of the CDC class driver functions as the CDCInterfaceInfo parameter. This stores each CDC interface's configuration and state information.
| struct { ... } USB_ClassInfo_CDC_Host_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.
Interface index of the CDC-ACM control interface within the attached device.
| struct { ... } USB_ClassInfo_CDC_Host_t::ControlLineStates |
Current states of the virtual serial port's control lines between the device and host.
Indicates if the CDC interface's IN data pipe should use double banking.
Pipe number of the CDC interface's IN data pipe.
Size in bytes of the CDC interface's IN data pipe.
Indicates if the CDC interface's OUT data pipe should use double banking.
Pipe number of the CDC interface's OUT data pipe.
Size in bytes of the CDC interface's OUT data pipe.
Control line states from the device to host, as a set of CDC_CONTROL_LINE_IN_* masks. This value is updated each time CDC_Host_USBTask() is called.
Control line states from the host to device, as a set of CDC_CONTROL_LINE_OUT_* masks - to notify the device of changes to these values, call the CDC_Host_SendControlLineStateChange() function.
Indicates if the current interface instance is connected to an attached device, valid after CDC_Host_ConfigurePipes() is called and the Host state machine is in the Configured state.
Line encoding used in the virtual serial port, for the device's information. This is generally only used if the virtual serial port data is to be reconstructed on a physical UART. When set by the host application, the CDC_Host_SetLineEncoding() function must be called to push the changes to the device.
Indicates if the CDC interface's notification pipe should use double banking.
Pipe number of the CDC interface's IN notification endpoint, if used.
Size in bytes of the CDC interface's IN notification pipe, if used.
| struct { ... } USB_ClassInfo_CDC_Host_t::State |
State data for the USB class interface within the device. All elements in this section may be set to initial values, but may also be ignored to default to sane values when the interface is enumerated.
