foxdie 4:486fec88517e 3
foxdie 4:486fec88517e 4 GMLAN is a Controller Area Network Bus used in General Motors vehicles from
foxdie 4:486fec88517e 5 roughly 2007-onwards. Its purpose is to allow various Electronic Control Units
foxdie 4:486fec88517e 6 (aka ECUs) within a modern vehicle to share information and enact procedures.
foxdie 4:486fec88517e 7
foxdie 4:486fec88517e 8 An example of this would be communication between the HU (Head unit) and the
foxdie 4:486fec88517e 9 DIC (Dashboard Information Cluster), when you adjust the volume up / down, this
foxdie 4:486fec88517e 10 is reported to the cluster to be displayed.
foxdie 4:486fec88517e 11
foxdie 4:486fec88517e 12 It is the function of this library to "crack open" this world to allow anyone
foxdie 4:486fec88517e 13 with only as little as a few hours of C++ programming under their belt to get
foxdie 4:486fec88517e 14 started in what can sometimes seem a daunting world.
