- common/io.h: describe the role of PROBE_TERM in version 3
- common/io.h (VERSION_ID): renamed to VERSION_ID1
- common/io.h (VERSION_ID2): added P2_0, and described version number
encoding
- cntr/cntr.h (enum hw_type): added HW_TYPE_V3
- cntr/cntr.c (init_io): decode version 3, flash LED three times, and
configure PROBE_TERM according to version
- cntr/cntr.h: new file for variables shared among cntr.c and ep0.c
- cntr/cntr.c (cntr), cntr/ep0.c (cntr): moved to cntr/cntr.h
- fw/common/io.h (VERSION_ID): we can detect the board version by reading
P2_1 (GND on version 1, open on version 2)
- cntr/cntr.c (init_io): added board version detection, board-specific
GPIO initialization, and a LED blink to indicate version 2
- cntr/cntr.h (hw_type), cntr/cntr.c (hw_type), cntr/ep0.c (my_setup),
common/config.h (HW_TYPE): the hardware type is now determined at run
time
