I have also tried to get the borders this way (cat keeps locked showing event by event, head shows only the first n): system("head -n 1 /dev/gpio-event"); gettimeofday(&start, NULL); system("head -n 1 /dev/gpio-event"); gettimeofday(&stop, NULL); Despite I've set EventBothEdges and the frequency is very low it quickly start to lose events, and it only shows rising edges (when set to show only falling it does, but still losing events). 114 R 1289454882.723571 GPIO Event: event lost due to queue full 114 R 1289454882.739990 GPIO Event: event lost due to queue full 114 R 1289454882.924774 GPIO Event: event lost due to queue full 114 R 1289454882.950866 GPIO Event: event lost due to queue full 114 R 1289454883.132141 GPIO Event: event lost due to queue full 114 R 1289454883.15 |
