- cntr/README, ecn/INDEX, ecn/ecn0006.txt: moved discussion of the input
circuit from README to ECN0006
- cntr/cntr.sch: changed pointer from README to ECN0006
- ecn/ecn0006.txt: added more measurements, explanations, and an analysis
of the situation
- cntr/README: change the name from "Arbitrary-precision counter" to
"Arbitrary-precision frequency counter"
- cntr/README: added list of known hardware issues
- 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
