Adding a New Link Node

Number settable by rotating switches, add pic to show MSB, LSB.

Type is in the FPGA.

Type is also in database templates.

Booting sequence:

mpsInitialize reads rotary switches for link node #, identity/type from FPGA.

loading db files uses C functions to look up loca and unit, load db with that loca and unit in the file name

mpsGetLinkNodeLOCA() and mpsGetLinkNodeUNIT() functions use link node ID # to index arrays at the top of drvMpsLinkNode.c:

char *primaries[50]

char *LOCATIONS[50]

char *locations[50]

char *UNITS[50]

char *units[50]

Add the loca and unit to these arrays following existing pattern.

Databases

• One substitutions for the things common to all link nodes, using mps.template, e.g. mpsLTU1MP12.substitutions
• One substitutions file for the flavor of link node, using mps.aln_template, mps.blm_template, mps.byk_template, mps.pic_template, e.g. mpsLTU1MP12.aln_substitutions
• Add new link node to Makefile, e.g. add lines DB += mpsLTU1MP12.template and DB += mpsLTU1MP12.aln_template
