OpenPlotter project

After investigation, it appears that my problem in zooming/panning was somehow linked to the fact that in OpenCPN the option 'Display/General/Chart display : enable chart quilting' was not selected (I'm using CM93). Once this option is activated, I couldn't reach the problem again. I'm now pretty sure (99.99%) the problem was NOT related to the recent update of openCPN (same behaviour between updated and not updated SDs).
Sorry for the alarm...

I haven't been able to reproduce your issue with "enable chart quilting" option and CM93 too. Do you have any extra chart loaded?

Open opencpn typing opencpn in a terminal to see error messages.

Yes, the 0.6.0 beta3 file is always the same.

Your Raspberry is model 2, isn't it?

Thanks for reporting!

Hi sailoog, thanks for your reply !

- The issue appeared when the option box was not checked. (i.e. no quilting). In fact I started from a position with a large scale available (e.g. an harbour) at the limit of OverZoom, and then zoomed out, and/or panned, the map did not draw (or maybe very slowly) in areas where the available scale is smaller (see capture, if I can join it !). The crash happened when zooming and panning repeatedly (I'm using CM93 - 2015).

- Typing openCPN in a terminal gives me the following message :
Xlib: extension "RANDR" missing on display ":1.0".

- My raspberry is a Pi2, I gave 128 M of ram to the GPU, no overclocking. I use it through SSH and tightvncserver as remote access from my window workstation.

I was looking at openplotter because i saw some great looking instroments. I searched openplotter and youtube using google.
My spanish is limited so i couldnt follow the you tube postings.
My question is, where did the spanish youtube guys get the really cool looking displays?
They are far better than the opencpn ones.

I havnt loaded openplltter as yet, as i am having issues downloading.
Thanks in advance

As far as a I know
The "cool looking" instruments come from a separate open source project called SignalK. The guys at OpenPlotter have built a bridge to SignalK but we are waiting for SignalK to deliver a useable set of dials.
Also waiting on a separate initiative from a guy in Uruguay.
In other words the dials are WIP

[Sailoog]

As affinite says, both of them are WIP.

On next release (openplotter v0.6.0 stable) the signalK instruments will be installed. I think they have made improvements.

And when the Uruguay friends are done with their development I will implement it to openplotter v0.7.0

Frustrated ...
Does OP detect a DS18B20 on startup or does it have to be configured somehow?
I have one of these 5pcs DS18B20 Waterproof Sensor Digital thermometer Thermal Probe UK | eBay
connected
gnd GPIO pin 6
data GPIO pin 7
Power GPIO pin 17
4.7k across data and power
I cant see that the 1BW page on OP shows anything (greyed out)

Connections are right. If you are using v0.6.0beta3 be sure to run:

cd
cd .config
rm -rf openplotter/
git clone https://github.com/sailoog/openplotter.git

There was a solved bug in the original v0.6.0beta3 you download.

edit: Run the code being connected to internet.

Thanks for reply

Yep done al above - no joy
replaced sensor - no joy
tried different GPIO pin - no joy
I'll try a complete reinstall to see if ive corrupted something.

Wait! type:

python /home/pi/.config/openplotter/imu/check_sensors.py

and paste what happens

Only will work with GPIO 4 (pin 7)

Thanks for sticking with me.
This is what I got

Nothing is detected, I assume you do not have any sensor (imu, humidity...)

last chance:

edit /home/pi/.config/openplotter/imu/check_sensors.py and replace line 48:

except: pass

by :

except Exception,e: print str(e)

save and type again

python /home/pi/.config/openplotter/imu/check_sensors.py

and paste what happens

Done

this is the result ?

Definitely the sensors is not detected, probably by a hardware failure?. Do what you wanted with a fresh installation, I have not more ideas

OK
Thankyou very much for your help.
I'll try a fresh instal and also see if I can get another PI setup
When/If I find the problem I will report back for others
