Open CPN on Rpi

[Phoenix of Hamble]

might just be a little more practical now....

new, much faster version launched (6x), at pretty much the same price

I'm getting quite excited about the possibilities with the newer, faster Raspberry Pis. I think the Mrs is starting to despair!

I had OpenCPN (Raspberry Pi version) running very well on a BeagleBone Black, which has a lot more grunt than an original Pi. Unfortunately it is broken by the latest version of Ubuntu ... ALSA sound library problems.

Banana pi is also worth a look. 1gig ram and sata.

Do I not recall some dodgyness with lemaker's product? Iffy drivers, software provided for download from public web space, incompatible/undocumented gpio pins? I seem to remember a lot of issues being raised with the banana pi. Have they all been resolved (or did I misremember that stuff?)?

Love the idea. Wonder what it does to power consumption.

According to comments in the discussion here:
http://www.raspberrypi.org/raspberry-pi-2-on-sale/

According to the presentation, idle consumption is comparable to the B+, peak consumption is comparable to the B model.

What those figures are I'll let someone else google

I can't help but wonder whether half the readership of PBO might grumble about the relevance of all this computer nonsense to boating. Is there a split in the forum audience depending on how, without other context, people would pronounce the word "router"? (Americans don't count here...)

Could have been, I might have missed it, just heard about them recently.

This guy has one working OK..

I have a Pi and a cubietruck already, so couldn't possibly justify spending 30 odd quid on another gadget......

 

[Cardo]

I think I'll be getting one and sticking RasPlex on it. That should do nicely for a media player, freeing up the iPad for other uses.

certainly does look interesting..

I just so happen to have a http://store.hackaday.com/collections/products-tools/products/usb-tester-2-0 sitting around. When monitoring the power consumption of the Raspi 2, there is a slight increase in power consumption over the Raspberry Pi 1.
When booting to a Raspbian desktop, the Raspberry Pi 1 draws about 290mA, dropping to about 250mA once the desktop is loaded. The Raspberry Pi 2 draws about 340mA at boot, dropping to about 270mA once the desktop is loaded. There is a slight increase in current draw from the Raspi 1 to the Raspi 2.
With a few experiments, I did determine the Raspberry Pi 2 will draw up to 500mA under heavy load. That’s the max spec for USB. If your current USB power adapter isn’t great, you might want to get a better one for the Raspi 2.

My Raspberry Pi 2 arrived this morning, and it's already running OpenCPN, ZyGrib and some other stuff.

30 minutes to compile openCPN is a great improvement; I expect to be able to publish scripts and .deb packages over the next few days for those that want them, work permitting.

Have you tried fldigi yet? I couldn't get the original pi working properly to reciever weatherfax.

Could you let me know which Alsa library openCPN expects? I've installed the current one on my BeagleBone, but that doesn't seem to be right.

What sort of screen/monitor do you use?
Also, how do you power the thing on the boat?

 

[richardabeattie]

I wonder what this thread is all about.

12V touch screen monitor (touch screen works with raspi)

Pi & peripherals off a USB hub, in turn powered from something like this: http://www.ebay.co.uk/itm/Power-Sup...arts_Vehicles_CarParts_SM&hash=item5affafdd12

Yes, fldigi's working; apt-get install fldigi

Wefax seems to be working OK, with no sign of the variable slant that the previous Pi models exhibited.
