Pi + Adafruit Kippah + 4.3" TFT

Hi there. I am trying to get a Kippah working with a 4.3" TFT screen. It's almost working, excepted that some colors are screwed up: Instead of http://reasonablycorrect.com/wp-content/uploads/2015/03/colorbars.gif I am getting http://imgur.com/download/4PC5jq8 Notice that the black is grey. Here's t...

Re: Using the 7" touch screen display for gps

I've been trying to figure out how to get it work but I'm having some troubles. I downloaded the from the first link you sent but as far as the maps and what to do after that I'm completely lost. Here's the documentation about OSM maps: http://wiki.navit-project.org/index.php/OpenStreetMap#Quick_St...

Re: Using the 7" touch screen display for gps

I think that it's more about ease of setup. I have personally used it with bluetooth devices ( Holux M1000 ), usb device ( GlobalSat BU-353-S4 ) and the Adafruit Ultimate GPS. I really like the Adafruit Ultimate GPS because it is really fast to acquire satellites ( faster than my M1000 ) and that's ...

Re: Using the 7" touch screen display for gps

FoxtrotGPS does not include a routing engine, so you need an online service to look for a route. The Navit version in the Jessie repository is quite outdated. It's better to get it from the official repo : https://github.com/navit-gps/navit/ They even have a raspbian-ua-netinst fork to setup Navit o...

Re: Using Pass-through for GPIO on pi zero / B+

The amp you listed seems to require a regular audio signal. So you would just use a jack connector. You just need to provide 5V and GND and it should work. AFAIK, you can't get an audio signal directly from the GPIO pins.

Re: USB gps problem

You should check with cgps to see if you get the data. If not, your problem is with gpsd (and we can dig). You can also try to configure Navit to read directly from the device and bypass gpsd : <vehicle name="Direct" enabled="yes" source="file://dev/ttyACM0" active="1"/> (more details at http://wiki...

Re: Carputer functions

Navigation: I have seen projects adding a GPS module, but not the navigation aspect which would include maps, turning directions, etc. I assume that this may not be practical, unless some software company that provides updated maps to GPS manufacturers will sell their information and it is formatte...
