Programming interface

The native programming interface between drasi and a readout is realised through a set of callback functions.

Caution

This section is under construction.

Readout callback setup

void lwroc_readout_pre_setup_functions()

Function defined by readout code. Should initialize _lwroc_readout_functions.

type lwroc_readout_functions

lwroc_init_func init

Readout callback functions

void lwroc_init_func()

Callback function called on startup.

void lwroc_uninit_func(int start_no_stop)

Callback function called on shutdown.

Parameters:

• start_no_stop – Heh?

void lwroc_start_stop_loop_func(int start)

Callback function called on start or stop.

Parameters:

• start – Call is for start.

void lwroc_idle_read_func()

Callback function called when no trigger has been found (a few times).

void lwroc_read_event_func(uint64_t cycle, uint16_t trig)

Callback function called for each trigger.

Parameters:

• cycle – Event counter.

• trig – Trigger number.

void lwroc_untriggered_loop_func(int *start_no_stop)

Callback function driving the readout.

void lwroc_cmdline_usage()

Callback function to print usage (help) info about command line options accepted by the readout lwroc_parse_cmdline_arg.

void lwroc_parse_cmdline_arg(const char *arg)

Callback function to parse a command line argument.

Parameters:

• arg – Command line argument.

Returns:

1 if the argument was recognised and parsed.
