|
|
|
|

|
41
|
|
|
|
|
|
|
Device::MegaSquirt provides operations for communicating with a MegaSquirt controller |
42
|
|
|
|
|
|
|
[http://www.msextra.com]. Operations such as reading/writing tables, |
43
|
|
|
|
|
|
|
reading live data, and writing configuration variables. |
44
|
|
|
|
|
|
|
|
45
|
|
|
|
|
|
|
This part of the module (Device::MegaSquirt) is a template and version specific |
46
|
|
|
|
|
|
|
modules (Device::MegaSquirt::*) implement the interface. |

The device ($dev) is the file name of the serial device on which |
61
|
|
|
|
|
|
|
the Megasquirt controller is connected (e.g.: /dev/ttyUSB0, /dev/ttyS0). |
62
|
|
|
|
|
|
|
|
63
|
|
|
|
|
|
|
C will attempt to open the device and determine the version and |
64
|
|
|
|
|
|
|
signature of the controller. It will return a version specific |
65
|
|
|
|
|
|
|
object on success. |
