Hi,
from the schematic it looks as if the outputs from both the LPR530AL as well as the LY530ALH sensor are processed using a HP/LP combination. However, the corresponding (not amplified) outputs (XOUT-1X, YOUT-1X, ZOUT-1X) don’t seem to be routed to the Atmega.
I’d like to be able to use the +/-1200°/s measurement range available on these lines. Is there any way to get access to them?
Thanks and best regards

Hi all,
I’m trying to connect the Razor 9DOF (AHRS firmware v1.1) to an OpenLog v1.61 module. At 19200 bps everything works as expected but if I change the AHRS code and OpenLogs config.txt to 57600 bps it doesn’t. The data is not completely corrupt as what happens if the baud rate is completely wrong. I can still see part of the data columns but it’s riddled with a lot of strange characters…
Any idea what happens here? I’ve selected “Adruino Pro or Pro Mini (3.3V, 8MHz) w/ ATmega328” in the GUI…

First meaningful data with Razor 9DOF AHRS set to 19200 bps and OpenLog (v2.2) to 9600 bps???

Hm, the 2.2 firmware is able to read out the disk info (see above) but if I let Razor AHRS and OpenLog run for a couple of minutes the logfile is there but empty :–(

With the 2.2 firmware I was now at least able to read out the card’s info:
Card type: SD2
Manufacturer ID: 3
OEM ID: SD
Product: SU02G
Version: 8.0
Serial number: 2611410752
Manufacturing date: 11/2009
Card Size: 1931264 KB

Different question concerning the latest 2.2 firmware:
I just tried to use that firmware trying to solve my problem mentioned earlier and found something weird: Although the baud rate is set to 9600 (no config.txt on the card, menu output) I have to connect to the OpenLog with 19200 bps…

BTW: I strongly support the idea of creating a trimmed-down version of the firmware that only supports raw logging, i.e. without the menu etc. This would not only allow – as you suggested – to increase the buffer but may also to add additional functionality.
Thanks!

Hi, great stuff, already started to assemble five Razor 9DOF+OpenLog for my experiments ;–)
However, I struggle to get this combination working and hope somebody is able to help me with this. I can connect to the OpenLog with the FTDI cable but “disk” only returns a “error reading disk info” and recording fails as no logfiles are created.
I’m using the 1.61 firmware with a 2GB card from SanDisk.
I already had to format the card once with a FAT 16 filesystem and also tried to repartition under Linux (mkfs.msdos)
Any ideas what could cause these troubles?
Thanks!
