Hello everyone, my name is Andrea.
I need your help!
I have a rasberry pi 3 with 7 "touchscreen
then I have a "adafruit ultimate gps"

I installed the "openplotter rpi v 0.8.0" program

I connected the gps to the "gpio 14 gpio 15"

not so what to do to show the gps and GPS data nmea 0183!

I tried various guides but nothing!

please, I need a guide
and on the openplotter settings, to use opencpn!

I'm a beginner, excuse me!
I am convinced that with your help I will solve this problem!
so I will no longer be in pericles with fog at sea!
many thanks in advance!

This isn't so much a "Brag" as a confession. This isn't pretty. I post this in hope that folks will advise ways to make this cleaner and easier to work with. I have not done much electronics tinkering, and lack craftsmanship.

My boat came with a set of dead Datamarine instruments. I had all of the old transducers removed and glassed over when I last hauled the boat. In retrospect I wish I had tried to save the paddle wheel. It also has an older 5 inch Garmin chartplotter with sounder.  I  also have a USB GPS dongle for location, but the Garmin is my only source of NMEA depth; it has a transducer epoxied inside the hull. I  use the Garmin at the helm, augmented by tablets and smartphones (Wilhelm SK on iOS is a brilliant app for instrument data). I don't have one of those newer angled pedestal guardrails, so I fashioned this arm that sets the GPS back freeing up room to mount gadgets.  

[Image: d4fdlPK5GuV9jWBAQWjPLqUTA20g9ol104TxRJe9...12-h950-no][Image: F5iKGGK6oCYfJHOxPl-IE-ceZDjd1Ox0dDWTcRWb...34-h949-no]

I added a masthead NMEA wind instrument, from Nasamarine. It didn't last long before water entered it and shorted/rusted out the electronics. I ordered a new circuitboard and gasket from England, and sealed some problem areas with silicone. This time it has lasted much better. I don't like the process of aligning it - shorting a couple of wires while the vane is pointed dead ahead - and wish there was a software offset in Openplotter for wind direction. 

When I pulled out the Datamarine instruments I saved the enclosure that was used for the "brain" of the system. Since there was a big hole cut in my hull liner for it, I thought it might be good to store the Pi there. I replaced the front (top, as I have it oriented) panel with a sheet of black hdpe, so I can put buttons and LEDs and such wherever desired. At the moment I have a momentary button I use to shut down the pi, a power LED, and a power switch. It's basically a bin that I shove the hub, the pi and its proto hat, and a wad of wires into.

[Image: bXkANRJm7dzq492admD6qmy2xNXKnrlOPZWtXilN...12-h949-no]

Hanging out the bottom of that is a brass terminal strip to which I've zip tied some DB9 breakout boards connected to the USB/Serial converters. The power supply and NMEA 0183 feeds from the Garmin and the masthead terminate here. Yeah, it's a mess. But it's all out of sight when I cram it back in the enclosure.

I have the two i2c components, the IMU and humidity sensor, mounted inside an RJ45 surface mount jack, as I have seen others do. I have this screwed to the bottom of a shelf in my nav station so that it is away from interference and heat of the pi. I also run the 1 wire stuff off of here for no good reason.

[Image: CsgDjtPDpnn6ucidiLsNe-5tnnX7qQfZ_otva20K...66-h949-no][Image: rm5xNI5jQepKlDY-JuOSEKEf7GRI1HKziMD6n3lZ...66-h949-no]

I have 4 one wire temperature probes. One is zip tied to the brass engine water intake thruhull. I call that sea temperature. I have one on the engine exhaust, and the radiator, and one in the ice box to monitor the beer temperature. 

On the proto hat I soldered my first surface mount chip... badly. Broke a leg but got the ADC to work. I measure house bank voltage using a little divider breakout. 

Just in front of the nav station I have a TV for the salon. It is on a mount that pivots 90 degrees so that it can face the seating area or serve as a monitor at the nav station. It is also visible from much of the cockpit in that position.

Very excited to have installed the Kip app for SignalK. FINALLY a practical (and attractive) instrument display for Openplotter. I also think it looks better than anything that is available for Android. Eager to get it customized to my liking.

I have an SDR going to a rail mounted antenna. This has stopped working, can't be enabled in Openplotter, on this trip to the boat. Not sure why. My home PC sees it. For that matter I have a wifi adapter doing the same thing. Seems like it might be the power from the hub is too weak or cables too long. 

Not pictured I have some inductive sensors, as suggested by Ole Saastad, on a water tank. I don't have them working through Openplotter yet. 

Any suggestions for cleaning up the wiring would be appreciated; connectors, busses, etc. 

I am not sure why my boat shows that it is moving a fractional knot most of the time. It started several openplotter versions ago.

Exclamation HELP! I screwed up GUI !
Posted by: Ontrackx - 01-14-2018, 03:24 PM - Forum: General discussion - Replies (5)

I was investigating into autostart of apps (installed some pacages from gui packages installer)

I now only boot into a weird desktop?

How can i execute this package/software gui from terminal? (try to uninstall latest package)

Or how to force an update from terminal to maybe save my system with that. (teamwiever is working) if anyone would have a look.

Or maybe this new GUI/desktop that i install can be minimized (how)

Please help the Vessel is going on voyage very soon and everything was up and running . But i HAAAAd to fiddle a little more

(I am a NOOB windows user that like GUI over terminal commands :Smile


  MPU 9255 change address
Posted by: Luckbert - 01-13-2018, 11:57 AM - Forum: How do I...? - Replies (4)

Hello, everyone,
I have connected two modules to my op system via I2C. 
GY-87 and a Mpu 9255. Both have the same address. Is it possible to change an address?(I don't understand the data sheets)
Or should I change my mind. 
Connecting mpu9255 via SPI?
Or 
Buy the sensors individually (air pressure and temperature) 

I only wanted to keep the GY because of air pressure and temperature. 
Greetings Jürgen

Hello, everyone,
I'm facing a problem.
I want to measure voltage with an ADS1115. So far, so good. I followed the docu procedure and get values. However, my output value shows 7000.00 V. However, a voltage source with 7 V is connected. How can I change the decimal place?
Greetings Jürgen


  Pulseaudio client.conf
Posted by: cmgreenman - 01-12-2018, 03:29 PM - Forum: General discussion - Replies (1)

Hello, 
    I'm trying to set up pulseaudio to stream to a bluetooth speaker.  There's a process somewhere that keeps overwriting my /home/pi/.config/pulse/client.conf file which disables autospawn and sets the pulse binary to /bin/true.  Where is this coming from so that I can disable it.  I plan to eventually install a stereo on the boat and direct wire using a DAC hat but for now all I have is bluetooth (external adapter) and the Pi's 3.5mm jack which is unusable due to the background noise.  



Here's what I'm trying to do.  I installed the NOOBS 0.10.0 version and have since upgraded to 0.17.0.  I have a set of custom scripts that I'm trying to get working that speak the boat speed and time at regular intervals (every 30 seconds for speed and every 15 minutes for time).  I have 2 custom services that I run as systemd User units.  One is a to-the-second scheduler script I wrote and the other is a daemon that uses inotify to watch a directory and then plays whatever audio file is dropped in there then deletes it.  When a file is dropped in the dir my playdaemon script detects it (inotifywait), records the current volume of all pulse sink-inputs, lowers all pulse sink-inputs by 15%, plays the voice file at the original volume, then brings all the volumes back up to their original values.  

I had this mostly working before on a ground up install using Raspbian Jessie but something else is clobbering my settings.  I've tried running pulse as a system instance but either I'm not configuring it right or again, something is borking it.  

Any suggestions?


  Open plotter browser language
Posted by: LarsD - 01-12-2018, 09:09 AM - Forum: How do I...? - No Replies

Hi, 
When using the browser (is it Chrome?) in my new open plotter installation for the first time I realise the browser itself comes up in a non English mode (meaning browser menus are non English) I guess it might be Bahasa Indonesia but I'm not sure.  

How do I go about changing this to something I can actually understand? 

Quite confusing...  Anyone that has a good suggestion? 
Kind regards 
Lars

I am a bit confused as to the output from SignalK. 
On the SK input diagnostics I get an understandable reading of 328.xxx deg., but the signalK value from the stream in NR shows a different value/format. How do I use this?
