#map1090

###BUILDING

Tested and working on Ubuntu 18.04, Raspbian Stretch, Buster

1. Install SDL and RTL-SDR libararies

sudo apt-get install libsdl2-dev libsdl2-ttf-dev libsdl2-gfx-dev librtlsdr-dev

Note: the sdl2-config output that would normally be passed to compiler flags points to the wrong directory on my distro. Instead I have manually linked to /usr/include/sdl2

Note: On Raspbian the SDL2 package requires X to be running. See the Raspberry Pi section for notes on running from the terminal and other improvements.

2. Download and build spidr

cd ~
git clone https://www.github.com/nmatsuda/spidr
cd spidr
make clean; make

3. Download and process map data Until more comprehensive map source (e.g., Mapbox) is integrated, map1090 uses the lat/lon SVG files from https://www.mccurley.org

The getmap.sh pulls the svg file for the contiguous 48 US states and produces a binary file for map1090 to read.

./getmap.sh

Android Notes [temp]

to change Android version or Arm type android/app/build.gradle -> set compileSdkVersion, targetSdkVersion, abiFilters android/sdl2/build.gradle -> set compileSdkVersion, targetSdkVersion, abiFilters

###RUNNING

1. Start dump1090 (http://www.github.com/MalcolmRobb/dump1090) locally in network mode:

dump1090 --net

2. Run map1090

./view1090 --fullsceen

map1090 will open an SDL window set to the resolution of your screen.

###RUNTIME OPTIONS

--server [domain name or ip] Specify a dump1090 server. Renamed from the view1090 "--net-bo-ip-addr" argument --port [port number] Specify dump1090 server port. Renamed from the view1090 "--net-bo-port" argument --metric Display metric units rather than imperial.

--screensize [width] [height] Specify a specific resolution to pass to SDL_RenderSetLogicalSize, otherwise use resolution of display --uiscale [scale] Scale up UI elements by integer amounts for high resolution screen --fullscreen Render fullscreen rather than in a window

###HARDWARE NOTES

map1090 is designed to be portable and work on a variety of systems, however it is intended to be used on a handheld device.

The software was originally develped for Raspberry Pi devices, and it is currently optimized for the Raspberry Pi 4 with the following configuration:

• Raspberry Pi 4
• A display:
  • [Pimoroni HyperPixel 4.0 Display] (https://shop.pimoroni.com/products/hyperpixel-4) *best overall, but requires some rework to use battery monitoring features of the PiJuice mentioned below
  • [Waveshare 5.5" AMOLED] (https://www.waveshare.com/5.5inch-hdmi-amoled.htm) *this is very good screen but the Google Pixel 2 phone mentioned below has a very similar display for the same price (along with everything else you need in a nice package)
  • [Waveshare 4.3" HDMI(B)] (https://www.waveshare.com/wiki/4.3inch_HDMI_LCD_(B))
  • [Adafruit 2.8" Capacitive Touch] (https://www.adafruit.com/product/2423)
• A battery hat, such as:
  • [PiJuice Battery Hat] (https://uk.pi-supply.com/products/pijuice-standard) *I2C pins must be reworked to connect to the Hyperpixel nonstandard I2C breakout pins, unfortunately
  • [MakerFocus UPS Hat] (https://www.amazon.com/Makerfocus-Raspberry-2500mAh-Lithium-Battery/dp/B01MQYX4UX)
• Any USB SDR receiver:
  • [Noelec Nano V3] (https://www.nooelec.com/store/nesdr-nano-three.html)
  • Stratux V2 *very low power but hard to find

If running as a front end only, with a separate dump1090 server, the best option is to use an Android phone, such as the Pixel 2, which significantly outperforms a Raspberry Pi 4.

map1090 has been tested on other boards such as the UP Core and UP Squared, but these boards have significantly poorer performance than the Raspberry Pi 4 with less software and peripheral support, so they are not recommended. With low resolution maps the software will run on these boards or even a Raspberry Pi Zero, so these remain options with some tradeoffs.

Of course, a variety of other devices work well for this purpose - all of the development so far has been done on a touchscreen Dell XPS laptop.
