November DV4mini Image Update

The K2DLS DV4mini image for the Raspberry Pi 2 and 3 (only!) has been updated to include the October 12 release of the DV4mini Control Panel.  This includes XRF through letter Z and REF up to 100 for the D-Star users.  The image will fit nicely on an 8 GB SD Card.

DV4mini RPi Image Updated to Raspbian Stretch

The K2DLS DV4mini image for the Raspberry Pi 2 and 3 has been updated to Raspbian Stretch.  The DV4mini client and BMXTG 1.3 start automatically upon boot.  VNC has been updated to RealVNC.  Both VNC and ssh are started by default.

The installation fits nicely on an 8 GB SD card and it looks great on my 7″ touchscreen display.

The default password for the pi user is “raspberry” — please change it immediately!

The image may be found here.

BMXTG 1.2 Released

The Brandmeister XTG Dialer (BMXTG) has been updated to version 1.2. Enhancements include automatic download of the masters address list and automatic download of talkgroup IDs and labels. Any talkgroup label may be changed through use of the talkgroups.conf file. Be sure to review the README file for changes.

The changes will make BMXTG easier to configure and the user no longer needs to be concerned about IP address changes of the BM servers. A simple stop and start of the program will refresh the server list and talkgroup list automatically.

I’ve also updated the DV4mini Raspberry Pi 2/3 image to include BMXTG v1.2.

RetroPie, A Tasty Gaming Platform

Retrogaming, the enjoyment of older computer based games and platforms, has been growing in popularity. I was intrigued a couple of years ago when, at a Vintage Computer Fest, I saw a multigame platform with hundreds of game ROMs copied onto a single emulation device. I had been wondering what the old games would look like connected via an HDMI input as opposed to the old low resolution RF transmitter method.

Then I came across the RetroPie project. RetroPie is a framework, delivered as an image, that allows you to run a number of game and computer system emulators on a Raspberry Pi. RPi models 2 and 3 are much better than older versions for this application. It is very simple to install and I was even able to use an old Colecovision controller to play Donkey Kong, Ladybug, and Carnival.

To connect the old controller, I came across a device called the Vision-daptor. One side sports a DB9 male connector, the other a USB B jack.  It arrived just a couple of days after my order.  The RPi recognized the device as a joystick controller without adding any additional drivers.

The Coleco emulation is handled by an optional component called CoolCV. CoolCV will also run under Linux, Mac and Windows. If you use a controller, rather than a keyboard, you may need to make some changes to key mappings in a configuration file.

There are plenty of sources for games online, but remember that games may still be covered by copyright. Some folks copy the contents of ROMs that they have purchased allowing them to play games for which they no longer have a gaming device. This requires some specialized hardware.

If you do download games via the internet, keep in mind that some sites may be vectors for the transmission of viruses and other malware. Exercise caution while you kill off those space invaders.  And the games do look great on an HDMI monitor!

New Raspberry Pi 2/3 DV4mini Image

Note: This image has been replaced by this one.

The DV4mini software developers have been hard at work fixing bugs, especially with DMR, and making things work better. So, I thought it time to create a new DV4mini RPi image for your enjoyment. I first built my own image last year when I wanted to have turnkey vnc access to my DV4mini/RPi system.

This build no longer contains the unsupported DV4MF2 software. Rather, it has the most recent version of the DV4mini dashboard (201.77), the updated dv_serial (20170106) and my add on Brandmeister XTG Dialer. If you haven’t used the XTG dialer before, you’re in for a treat. It works great with a touchscreen display, but just fine with a keyboard and a mouse too. You might need to edit a couple of text files to set it up to your liking. For details, see /opt/dv4mini/bmxtg/README once you have the distro up and running.

Important default password info follows.

root / raspberry
pi / dv4m

vncviewer – dv4m

You SHOULD change the default passwords after you get things going. The standard unix passwd command is used to change the root and pi passwords. To change the vnc password, use x11vnc -storepasswd.
