socketcan [WIP]
socketcan provides an interface to a CAN bus to read and write frames. The library is based on the SocketCAN network stack on Linux.
Features
- supports kernel timestamps for received frames
- receive and parse error frames
- CAN filters
- interfaces:
- simple
io.ReadWriteCloserinterface (viaos.File) - more sophisticated
SendandReceivemethods to handle out-of-band ( oob) data like timestamps
- simple
- no dependencies beside

Types ¶
type CanError ¶
type CanError struct {
Class uint
Detail uint
Location uint
// contains filtered or unexported fields
}
CanError contains the error information parsed from CAN error frames
func ParseCanErrors ¶
ParseCanErrors returns the CAN errors from given CAN frame
type MultipleError ¶
type MultipleError struct {
// contains filtered or unexported fields
}
MultipleError implements the error interface and may contain multiple errors
func (*MultipleError) Add ¶
func (e *MultipleError) Add(err error)
Add adds the given error to the contained errors
func (*MultipleError) Err ¶
func (e *MultipleError) Err() (err error)
Err returns, dependent upon the count of contained errors, nil, the one contained error or the MultipleError itself. This should be returned as error to the calling function.
func (*MultipleError) Error ¶
func (e *MultipleError) Error() (s string)
Error implements the error interface
func (*MultipleError) Errors ¶
func (e *MultipleError) Errors() (errs []error)
Errors returns the contained errors
