Detailed Description

Pixie module related things that should not change between revisions.

"Constant" constants, i.e. those who won't change going from different verison (revision) of board, some magic numbers used in code etc. For "variable" constants i.e. revision related or experiment related see Globals class.

Variable Documentation

const pixie::word_t pixie::clockVsn = 1000

An arbitrary vsn used to pass clock data

const size_t pixie::numberOfChannels = 16

Number of channels in a module.

const unsigned int pixie::TOTALREAD = 1000000

THIS SHOULD NOT BE SET LARGER THAN 1,000,000 this defines the maximum amount of data that will be received in a spill.

const pixie::word_t pixie::U_DELIMITER = (pixie::word_t)-1

buffer and module data are terminated with a "-1" value also used to indicate when a quantity is out of range or peculiar data this should theoretically be the same as UINT_MAX in climits header
