Detailed Description

Interface with DAQ via a WishboneInterface.

This is a very light class focused on just providing helpful functionality. Constructing/deconstructing these objects is very\ light so it can be done often.

getLinkSetup()

virtual void pflib::DAQ::getLinkSetup ( int ilink, int & l1a_delay, int & l1a_capture_width )

pure virtual

read link parameters into the passed variables

Implemented in pflib::bittware::HcalBackplaneBW_Capture, pflib::FiberlessCapture, and pflib::zcu::ZCU_Capture.

read_event_sw_headers()

std::vector< uint32_t > pflib::DAQ::read_event_sw_headers

(

)

readout an event including emulation of the headers the firmware inserts

The Bittware firmware includes headers when copying the data into the axi stream and we include those here so that the non-axis readout can have data that is in the same format as axis data.

this is just a helper function so that we can avoid repeating the emulation of the extra headers wrapping an ECOND packet between the HcalBackplane and EcalSMM targets.

Besides these emulated headers, it just uses getLinkData to get data and advanceLinkReadPtr after gathering one sample of data.

Note

only one elink right now

TODO: update to match FW, I just set ievt, soi, and subpacket size to zero

setup()

virtual void pflib::DAQ::setup ( int econid, int samples_per_ror, int soi = -1 )

inlinevirtual

setup overall event information for daq channels

setupLink()

virtual void pflib::DAQ::setupLink ( int ilink, int l1a_delay, int l1a_capture_width )

pure virtual

Setup a link.

Implemented in pflib::bittware::HcalBackplaneBW_Capture, pflib::FiberlessCapture, and pflib::zcu::ZCU_Capture.
