Hello Time-Nuts, after I finally managed to get my TAPR TIC into a case, together with two 1PPS dividers, I wanted to give the 3 channel measurement a try. I remember that I successfully used the TimeLab mode some years ago, but this time I can´t get it to work. I installed the lasted firmware (binary from github). Channel A and B work fine, but the (B-A) doens´t seem to be calculated - see output from TIC below. Should the line reading "debug" in the TIC Configuration make me nervous? Any help highly appreciated... Thanks & have a nice weekend, Matthias # TAPR TICC Timestamping Counter # Copyright 2016-2020 N8UR, K9TRV, NH6Z, WA8YWQ ##################### # TICC Configuration: # Measurement Mode: TimeLab 3-channel Debug # Poll Character: none # EEPROM Version: 10, Board Version: D # Software Version: 20200412.1 # Board Serial Number: A92D670B # Clock Speed: 10.000000 MHz # Coarse tick: 100.000000 usec # Cal Periods: 20 # Timestamp Wrap:  0 # SyncMode: M # Ch Names: A/B # PropDelay: 0 (ch0), 0 (ch1) # Timeout: 0x05 # Trigger Edge: R (ch0), R (ch1) # Time Dilation: 2500 (ch0), 2500 (ch1) # FIXED_TIME2: 0 (ch0), 0 (ch1) # FUDGE0: 0 (ch0), 0 (ch1) ##################### # Type any character for config menu # ............................ # timestamp chA, chB; interval chA->B (seconds with 11 decimal places) 1.14527049228 A 0.16498914776 B 2.00000000001chC (B-A) 2.14527049186 A 1.16498914789 B 3.00000000001chC (B-A) 3.14527049132 A 2.16498914799 B 4.00000000001chC (B-A) 4.14527049068 A 3.16498914839 B 5.00000000001chC (B-A) 5.14527049019 A 4.16498914834 B 6.00000000001chC (B-A) 6.14527048961 A 5.16498914850 B 7.00000000001chC (B-A) 7.14527048907 A 6.16498914865 B 8.00000000001chC (B-A) 8.14527048859 A 7.16498914890 B 9.00000000001chC (B-A) 9.14527048800 A 8.16498914895 B 10.00000000001chC (B-A) 10.14527048751 A 9.16498914913 B 11.00000000001chC (B-A) 11.14527048687 A 10.16498914928 B 12.00000000001chC (B-A) 12.14527048644 A 11.16498914941 B 13.00000000001chC (B-A) 13.14527048602 A 12.16498914966 B 14.00000000001chC (B-A

Hi Matthias -- I just took a look at the source and the "Debug" is meaningless... stupid program error (missing a "break" in a case statement) caused that to be printed when it shouldn't be. Easy fix. But why you're seeing the bogus chC results will take a little more investigation. I suspect it's something that broke when I made changes to the print routine in the latest version. I'll see if I can figure it out, and if/when I do I'll push changes to the github repository. Thanks for letting me know about the problems!
