Try installing the release version. There are no more processes running than Raspbian.

Re: Fedora 23 ARM & Raspberry Pi 3

Thanks! It works just fine. What does the name "test" imply? If I do regular dnf updates, will it eventually converge with the final version?

Re: JavaFX Chartplotter to Raspberry Pi Project

I have been developing an ENC rendering backend for use in various nautical chart applications. It uses awt.graphics2d, which I believe can be displayed in JavaFX apps. I have also written decoders for S-57 ENC files and OpenStreetMap OSM files.

Is this of interest to you?

Re: SSH With hostname

Even simpler is to install the avahi daemon ("sudo yum install avahi"). Then you can use "<hostname>.local" to address the Raspi. Both Linux and Mac OSX computers have the corresponding client (nss-mdns for Linux, Bonjour for Mac) installed by default. I don't know about Windows. You will need to in...

Re: RaspberryPi and iMac 27"

No. The display port on the Mac is an output, not an input.

You will need a monitor or a TV with an HDMI input.

Once you have the Pi set up & running a VNC server, you can then use the Mac via Ethernet. The Mac's screen sharing utility works as a VNC client.

Re: GPIO

"About 16" the good lady says. With that number, the possibilities are endless for both parallel and serial port types.

To make this fly, though, the GPIOs would ideally need to have edge-detecting interrupts available.
Does the Broadcom chip have these?

... an external board with buffers, level conversion and analog I/O rather than soldering directly onto the main board.

So presumably the power rails will also be brought out on the connector?
