Re: [Elphel-support] Fwd: expected imu data fortmat
Oleg, I've done the suggested test and also copied over the IMU_LOGG.XML file. All of this can be found in the zip file here. I did use the parser 'read_imu_log', however, I'm still not sure if the results make sense. Also, the parser would time-out*, but perhaps that's because I'm running it in the browser. 1) Does the logged data look problematic? 2) Just in case this is helpful, when running the "advanced webcam" tool, despite GPS being connected I still get "GPS not detected". Thank you Oleg in advance for your help. -Hamid * Fatal error: Maximum execution time of 30 seconds exceeded in /mnt/flash/html/read_imu_log.php on line 101 On 10/03/2014 05:59 PM, Oleg wrote: Hello Hamid, Yes, the data from 'fpcf -imu 1 | grep "0:"' looks wrong. I guess, the best way to troubleshoot would be sending the camera to us. Or you can try to record a log and check what's inside or send it to us. 1. Record a log (do you have a CF card inside?) - START: http://192.168.0.9/logger_launcher.php?file=/usr/html/CF/test.logindex=1n=100 STOP: http://192.168.0.9/phpshell.php?command=killall%20-1%20log_imu You can open the "logger_launcher.php" and check what actual commands are executed. 2.

The goal is to save pictures with known position and orientation (derivable from IMU). I've tried to get up to speed using the wiki and past e-mails, but am still having trouble. Here is my first question: 1) What is the data format of the imu data? When running cat /dev/imu a series of non-ascii characters are printed. Hence, either the data is streamed in a binary format or the communication settings are incorrect. If helpful, here are some outputs fpcf -imu 1 | grep "0:" 0: 1387427810.526442 (0x52b277e2 0x8086a) 0x 0x 0x 0x 0x 0x 0x 0x 0x 0x 0x 0x 0x 0x 0: 1387427810.526849 (0x52b277e2 0x80a01) 0x 0x 0x 0x 0x 0x 0x 0x 0x 0x 0x 0x 0x 0x 0: 1387427810.527255 (0x52b277e2 0x80b97) 0x 0x 0x 0x 0x 0x 0x 0x 0x 0x 0x 0x 0x 0x ^C fpcf -imu 1 | grep "1:" 1: 1387425332.154346 (0x52b26e34 0x25aea) 0xf0414001 0x174e8544 0x1390cef8 0x7f7468e3 0xfff00f0d 0xfffcdfcd 0xc5ff 0x 0x 0x 0x 0x 0x 0x 1: 1387425332.154346 (0x52b26e34 0x25aea) 0x1c12 0x 0x 0x 0x 0x 0x 0x 0x 0x 0x 0x 0x 0x ^C Thanks in advance, -Hamid

Hello Hamid, The parsed logged data looks ok - both, GPS and IMU. * Fatal error: Maximum execution time of 30 seconds exceeded in /mnt/flash/html/read_imu_log.php on line 101 The timeout can be set in the PHP configuration Please, let me know if you need any further help.

Re: [Elphel-support] Fwd: expected imu data fortmat
Oleg, Right now the imu rate is about 2500 samples per second. Is the configuration parameter 'imu_period' used to reduce the rate of the imu? According to documentation: imu_period - set the IMU logging period in SPI SCLK periods, maybe set to auto (default value, same as 0xff00) to log when the IMU data is ready. Value 0 turns the IMU logging off The mapping from imu_period to logging rate is unclear to me. For example, if you want 1 Hz do you set imu_period to 5e6? -Hamid On 10/06/2014 01:48 PM, Oleg wrote: Hello Hamid, The parsed logged data looks ok - both, GPS and IMU. * Fatal error: Maximum execution time of 30 seconds exceeded in /mnt/flash/html/read_imu_log.php on line 101 The timeout can be set in the PHP configuration Please, let me know if you need any further help.
