ALDL Dashboard for RPi systems
------------------------------

Latest code can be found at:

   http://git.shaftnet.org/cgit/users/pizza/public/aldl_pi.git

This interfaces with General Motor's ancient 160 baud "Pin E" ALDL protocol
to create a virtual dashboard capable of displaying any data that the 
ECU reports.  It is intended to be used with a Raspberry Pi's composite
video output, and collects its data using one of the RPi's GPIOs.

  For more information on the 160 baud ALDL protocol, see:

    https://en.wikipedia.org/wiki/ALDL 
    http://www.techedge.com.au/vehicle/aldl160/aldl160b.htm 

  More modern "Pin M" 8192 ALDL systems are not supported!  For those, 
  there are several alternative projects, including:

    http://git.shaftnet.org/cgit/users/pizza/public/linuxaldl.git/
    http://fbodytech.com/misc/raspberry-pi-dashboarddatalogger/
    https://github.com/resfilter/aldl	

Dashboard rendering, data acquiition, and ALDL protocol handling are 
modular, so this code should be easily extendible to other vehicles and 
computing platforms.

Compilation requires the wiringPi, SDL2, and SDL2_ttf libraries.

NOTE:  Physical interfacing of the vehicle to the RPi is beyond the
scope of this README.  Do not blame me if you blow up your RPi or the
ECU on your vehicle!

This currently only supports the A179 datastream, used by, among others, 
1992-1995 C/K trucks with manual transmissions.  As you may surmise, I 
own one of these vehicles.

So. This software was written to meet my own needs, but I'm releasing it 
under the GNU GPLv3 in the hopes that others will find it useful.  If you
do, I'd appreciate an email!
