Macro Definition Documentation


Pipe address for the default control pipe, which always resides in address 0. This is defined for convenience to give more readable code when used with the pipe macros.

#define PIPE_EPNUM_MASK   0x0F

Endpoint number mask, for masking against endpoint addresses to retrieve the endpoint's numerical address in the attached device.

#define PIPE_PIPENUM_MASK   0x0F

Pipe number mask, for masking against pipe addresses to retrieve the pipe's numerical address in the device.
