2 kusanagi 2.2
3     Functions to read AC physics data (ACphysics) and AC calibration
4     data (ACcalib).
5 kusanagi 2.1 Author: Petter Hofverberg, petter@particle.kth.se
6    
7 kusanagi 2.2 0410 v1.0 alive
8 kusanagi 2.5 0412 v1.1 fixed problem with found, and changed headers
9 kusanagi 2.8 0502 v1.2 added a crc check
10 kusanagi 2.10 0502 v1.3 increased buffer size
11 kusanagi 2.2
12 kusanagi 2.1 Errors: (returned to the main program as the variable "err")
13     err=
14 kusanagi 2.2 0xFF - data (physics or calibration) from both cards found
15     0xF0 - only data from main card found
16     0x0F - only data from extra card found
17     0x00 - no data found
18 kusanagi 2.1
19 kusanagi 2.8 CRCcheck: 1 - OK, 0 - error
