Description
(23:15:30) chtr: would it be possible for you to get logging of the microstrain, the gps, and the encoders done for this weekend?
(23:15:39) tommost: Oh, sure. Crudely.
(23:16:39) chtr: alright, i'll probably be back in the haute sometime saturday, so i was planning on driving it around a bit and getting some data to work with.
(23:18:01) tommost: Do you want every bit of information that they provide or checkpoints of current data (say, every quarter second)?
(23:18:34) chtr: we're polling the motor controllers at 10Hz, so that would be fine
(23:20:30) tommost: Okay. I can do that really easily (just spawn a thread that logs the current state variables to a file).
(23:20:35) tommost: What format would you like?
(23:20:40) tommost: CSV? TSV?
(23:20:56) chtr: either's fine
(23:26:21) tommost: What data, specifically? I'm thinking timestamp, gps lat/lon, left/right speed, left/right ticks, microstrain 3-axis heading/speed/accel.
(23:27:02) chtr: that (except the ticks, they don't exist.) and the gps heading and velocity
(23:28:14) tommost: Would you like the GPS's reported error as well?
(23:28:20) chtr: sure
(23:28:36) tommost: Okay, well, that's pretty much everything.
(23:28:49) chtr: good
(23:29:58) tommost: There are independent timestamps for the GPS and MicroStrain data. Would you like those as well, just for completeness's sake?
(23:30:39) chtr: sure. hell, just log everything. we can always strip out whatever's irrelevant later.
(23:30:50) tommost: Okay.
