- 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
- cntr/README: description of the counter board and its application
- cntr/fw/common/crc32.c: variant of CRC32-IEEE802.3 shared by firmware and
measurement application
- cntr/fw/cntr/ep0.c (my_setup), cntr/tools/cntr/cntr.c (get_sample):
protect the counter value with a CRC and an one's complement copy
- cntr/fw/include/cntr/ep0.h: oops, wasn't checked into repository
- cntr/tools/cntr/cntr.c: added section titles
- cntr/tools/cntr/cntr.c (measure): show communication statistics at the end
- cntr/tools/cntr/cntr.c (measure, usage, main): new option -d to enable
reporting of communication errors
- cntr/tools/cntr/cntr.c (set_stop, measure): let user stop measurement with
SIGINT
- cntr/tools/cntr/cntr.c (measure): get multiple "first samples" and keep
the one with the shortest round-trip time
- cntr/tools/cntr/cntr.c (measure): changed unit "ppk" (1/1000) to percent
(1/100)
- cntr/tools/cntr/cntr.c (usage, main): command-line argument is now the
accuracy goal, while the system clock deviation is set with the new
option -c
- TODO: some more things to do
