We’ve got a wiki page with instructions on how to connect the HST-WSU 200. ArduPilot does not yet support reading in the temperature from NMEA devices but I will hopefully add support for this in the coming weeks and then hopefully include it in the Rover-4.1 beta release which should start within a couple of weeks.
We’ve added support for reading the temperature from a NMEA sonar and this will go out with Rover-4.2.0-beta2 within a couple of days. Txs again for the report.
Sorry I didn’t see your other comment earlier. To give some higher level information, you need to be using an ArduPilot compatible autopilot (there are many to choose from) and then you need to attach a “digitizer” (e.g. the DST-2) to the sonar to convert the analog signal to the NMEA protocol. Then you must connect this NMEA output cable from the digitizer to one of the autopilot’s telemetry ports as described on the wiki.
my dataflash has no DPTH - log_bitmask=65535 - how do we turn it on ? ardurover v4 pixhawk and ping1d which is using SONARRANGE nicely - just not logging…
The most common issue is the RNGFNDx_ORIENT parameter needs to be set to 25 (it defaults to zero).
How do I set the appropriate throttle? My differential control boat, which parameters can be set to make a gentle and gentle U-turn and sharp-angle turn, the action is too intense now
Can you post an onboard log of the vehicle doing a turn?
I want to install the Echologger ECT400 on my Pixhawk Cube orange.
(firmware Rover 4.1.4 OFFICIAL, mission planner 1.3.75)
In my full parameter list, I can’t find the following parameters.
RNGFND1_MIN_CM = 13
RNGFND1_MAX_CM = 10000 (i.e. 100m). This is the distance in centimeters that the rangefinder can reliably read.
RNGFND1_ORIENT = 25 (i.e. down) if mounted on a boat
Will this be a problem for the installation and operation of the Echologger ECT400?
have you enabled one of the rangefinders within the parameters yet? Until you enable one of the rangefinders and refreshed parameters you will not see those until you do so. once enabled do a parameter refresh and you should now have a drop down menu with all those options.
By the way, we hide some parameters until the _TYPE or _ENABLE parameter is set to a non-zero value to reduce the parameter list for users. We have so many features in AP that we also have a massive number of parameters (well over 1000) so hiding some helps keep things manageable.
Thanks for your respons. Problem is solved
Hello to everyone,
first of all I’ve bought echologger ect400 with serial output. The echo sounder has arrived and I am very enthusiastic about the first results on the pc.
However, I’m having trouble connecting to pixhawk (the orange cube). For the connection I am using a converter (I have already tried two different ones) rs232-ttl and despite all the parameters are set correctly as in the wiki (Echologger ECT400 echosounder — Copter documentation) the data did not arrive at the pixhawk. Also the converters microcontroller get very hot, and this seems very strange to me. The echo connected directly (rs232-usb) to the pc transmits data without problems. The converters get hot only when the ect400 is working. If for example I invert tx with rx (I’ve done it because I thought the connection was wrong), the max3232 get cold. I can’t understand what’s happening.
Thanks in advance for help/reply
hmmm… hard to guess what the issue could be. We probably need to see the serial output that the echologger is outputting.
Maybe also include a parameter file or better yet an onboard so we can check the parameters. It may be necessary to set LOG_DISARMED = 1 to produce a log while the vehicle is disarmed.
Thank you for the reply.
Ok, I’ll do them. I’ve set ect400 to “altitude nmea” autput, and I see this protocol on serial log. I think that there’s something of wrong on hw point of view. Serials converters wouldn’t get hot as they became at the moment.
It was caused by a wrong conection with the M-M serial adapter!
Any idea to how to export a .csv file from log with X, Y, Helipsoid alt, depht?
Thanks in advance
Great! We have some information on this wiki page re how to extract DPTH message to a .csv file using mP.
Few water surface features may lead to holes in data acquisition modeling. Is there a better solution for this?
