- 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
