Executive Summary
Chris Hopwood and Robert Fendricks will be working on a way to interface the Beaglebone Black with a GPS tracker using UART. We plan on using this data to track the Bone's location on a map via a web interface.

Packaging
If you have hardware, consider Small Build, Big Execuition for ideas on the final packaging.

Installation Instructions
Give step by step instructions on how to install your project.


 * Include your github path as a link like this to the read-only git site: https://github.com/MarkAYoder/gitLearn.
 * Be sure your README.md is includes an up-to-date and clear description of your project so that someone who comes across you git repository can quickly learn what you did and how they can reproduce it.
 * Include a Makefile for you code.
 * Include any additional packages installed via opkg.
 * Include kernel mods.
 * If there is extra hardware needed, include links to where it can be obtained.

GPS
The GPS we are using is MTK3339

To load the device tree overlay on the beaglebone:  root@beaglebone# echo BB-UART4 > /sys/devices/bone_capemgr.*/slots  This will connect UART4-rx onto P9_11.

To find which tty the UART is exposed as, run: root@beaglebone# dmesg | tail On our beagle it outputted:  [  50.991396] bone-capemgr bone_capemgr.8: slot #8: 'Override Board Name,00A0,Override Manuf,BB-UART4' [  50.991495] bone-capemgr bone_capemgr.8: slot #8: Requesting part number/version based 'BB-UART4-00A0.dtbo [  50.991514] bone-capemgr bone_capemgr.8: slot #8: Requesting firmware 'BB-UART4-00A0.dtbo' for board-name 'Override Board Name', version '00A0' [  50.991542] bone-capemgr bone_capemgr.8: slot #8: dtbo 'BB-UART4-00A0.dtbo' loaded; converting to live tree [  50.991860] bone-capemgr bone_capemgr.8: slot #8: #2 overlays [  50.995484] 481a8000.serial: ttyO4 at MMIO 0x481a8000 (irq = 61) is a OMAP UART4 [  50.996082] bone-capemgr bone_capemgr.8: slot #8: Applied #2 overlays. [  51.171271] [drm:output_poll_execute], [CONNECTOR:5:HDMI-A-1] status updated from 2 to 2 [  61.202485] [drm:output_poll_execute], [CONNECTOR:5:HDMI-A-1] status updated from 2 to 2 [  71.233751] [drm:output_poll_execute], [CONNECTOR:5:HDMI-A-1] status updated from 2 to 2



According to [  50.995484] 481a8000.serial: ttyO4 at MMIO 0x481a8000 (irq = 61) is a OMAP UART4 our port is mapped to ttyO4.

To test if the GPS is connected correctly, run:  root@beaglebone# screen /dev/ttyO4 9200  replacing ttyO4 with whatever device dmesg reported earlier.

To disconnect from the screen session correctly, press + +<:>, then type ":quit"

User Instructions
Once everything is installed, how do you use the program? Give details here, so if you have a long user manual, link to it here.

Highlights
Here is where you brag about what your project can do.

Include a YouTube demo.

Theory of Operation
Give a high level overview of the structure of your software. Are you using GStreamer? Show a diagram of the pipeline. Are you running multiple tasks? Show what they do and how they interact.

Work Breakdown
We first attempted to connect to the Beaglebone via the included FTDI cable. Here is a link to the FTDI cable's ref. sheet: http://www.ftdichip.com/Support/Documents/DataSheets/Cables/DS_TTL-232R_CABLES.pdf. To connect the

List the major tasks in your project and who did what.

Also list here what doesn't work yet and when you think it will be finished and who is finishing it.

Future Work
Suggest addition things that could be done with this project.

Conclusions
Give some concluding thoughts about the project. Suggest some future additions that could make it even more interesting.
