void ola::plugin::usbpro::EnttecPortImpl::Branch	(	const ola::rdm::UID &	lower,
		const ola::rdm::UID &	upper,
		BranchCallback *	callback
	)

virtual

Send a Discovery Unique Branch

Implements ola::rdm::DiscoveryTargetInterface.

void ola::plugin::usbpro::EnttecPortImpl::GetParameters ( usb_pro_params_callback * callback )

Send a request for the widget's parameters. TODO(simon): add timers to these

void ola::plugin::usbpro::EnttecPortImpl::HandleIncomingDataMessage	(	const uint8_t *	data,
		unsigned int	length
	)

Handle an incoming frame.

Parameters

data	the incoming data buffer
length	the length of the data buffer.

The first byte is a status code: 0: good, non-0: bad The second byte is the start code The remaining bytes are the actual data.

void ola::plugin::usbpro::EnttecPortImpl::HandleRDMTimeout ( unsigned int length )

Called to indicate the completion of an RDM request. According to the spec: The timeout message will follow the RDM discovery reply message, whether or not the reply is partial or complete. The timeout message will follow the RDM reply message (GET or SET), only when the reply is incomplete or unrecognizable.

Experiments suggest that sending another RDM message before this 'timeout' is received results in Bad Things Happening.

The length of this message should be 0.

void ola::plugin::usbpro::EnttecPortImpl::MuteDevice	(	const ola::rdm::UID &	target,
		MuteDeviceCallback *	mute_complete
	)

virtual

Mute a responder

Parameters

target	the UID to mute
mute_complete	the callback to run once the mute request completes.

Implements ola::rdm::DiscoveryTargetInterface.

void ola::plugin::usbpro::EnttecPortImpl::RunFullDiscovery ( ola::rdm::RDMDiscoveryCallback * callback )

virtual

Start full discovery for this widget.

Implements ola::rdm::DiscoverableRDMControllerInterface.

void ola::plugin::usbpro::EnttecPortImpl::RunIncrementalDiscovery ( ola::rdm::RDMDiscoveryCallback * callback )

virtual

Start incremental discovery for this widget

Implements ola::rdm::DiscoverableRDMControllerInterface.

bool ola::plugin::usbpro::EnttecPortImpl::SendDMX ( const DmxBuffer & buffer )

Send a DMX message

void ola::plugin::usbpro::EnttecPortImpl::SendRDMRequest	(	ola::rdm::RDMRequest *	request,
		ola::rdm::RDMCallback *	on_complete
	)

virtual

Send an RDM Request.

Implements ola::rdm::RDMControllerInterface.

void ola::plugin::usbpro::EnttecPortImpl::SetDMXCallback ( ola::Callback0< void > * callback )

Set the callback to run when new DMX data arrives

bool ola::plugin::usbpro::EnttecPortImpl::SetParameters	(	uint8_t	break_time,
		uint8_t	mab_time,
		uint8_t	rate
	)

Set the widget's parameters. Due to the lack of confirmation, this returns immediately.

void ola::plugin::usbpro::EnttecPortImpl::UnMuteAll ( UnMuteDeviceCallback * unmute_complete )

virtual

Unmute all responders

Parameters

unmute_complete the callback to run once the unmute request completes.

Implements ola::rdm::DiscoveryTargetInterface.
