41             =head1 SYNOPSIS
42            
43             This module provides a Perl interface to a device containing an Elm Electronics ELM327 OBD Interpreter and provides access to the following functions:
44            
45             Read OBD parameters and extract individual values from results.
46             Read OBD Trouble Codes and expand them to their full form.
47             Reset OBD Trouble Codes.
48             Read ELM327 parameters.
49             Write and write the ELM327 data byte.
50             Calibrate ELM327 Voltage.
51             Switchable diagnostic trace and replay function for debugging.
52            
53             The module is written entirely in Perl and works with both Linux and Windows. Depending on which operating system it is run on it uses either the Win32::SerialPort or Device::SerialPort module (which you'll need to install first) so it should work on any platform that supports one of them.
54            
55             use Device::ELM327;
56            
57             my $obd = Device::ELM327->new();
58            
59             # Read status information...
60             $obd->Show("ELM identity");
61             $obd->Show("Vehicle Identification Number");
62             $obd->Show("Engine RPM");
63             $obd->ShowTroubleCodes();
64            
65             undef $obd;
66            
67             =head1 SUBROUTINES/METHODS
68            
69            
70             =head2 new - the constructor for the module.
71            
72             To open the device and have it search for an ELM module:
73            
74             my $obd = Device::ELM327->new();
75            
76             If you know the port name (e.g. 'COM5', '/dev/ttyUSB7' etc) it may be
77             quicker to pass it into the function:
78            
79             my $obd = Device::ELM327->new($port_name);
80            
81             To override the default serial port settings (38400, no parity, 8 data
82             bits, 1 stop bit, no handshaking), you can pass values with or instead
83             of the port name:
84            
85             my $port_details = "/dev/ttyUSB0:115200:none:8:1:none";
86             my $obd = Device::ELM327->new($port_details);
87            
88             The port name may be left out:
89            
90             my $port_details = "115200:none:8:1:none";
91            
92             It is also ok to just define the port name and/or baud rate and use
93             default values for parity, data bits, stop bits and handshake:
94            
95             my $port_details = "/dev/ttyUSB0:115200";
96            
97             or
98            
99             my $port_details = "115200";
100            
101             If you want extra debugging information, it can be enabled by setting
102             $debug_level to a positive number in the range 1 to 3, with more
103             information being displayed as the number increases:
104            
105             my $obd = Device::ELM327->new($port_name, $debug_level);
106            
107             A value of either undef or "" can be passed for the $port_name:
108            
109             my $obd = Device::ELM327->new("", $debug_level);
110            
111             The module can replay previously captured debugging information:
112            
113             my $obd = Device_ELM327->new(undef, $debug_level, $replay_filename);
114            
115             To produce a file containing replayable data simply set $debug_level to
116             1 or higher and pipe the output to a text file:
117            
118             perl test.pl>test_output.txt

2838            
2839             Returns a value from the last set of results from the ELM/ECU
2840            
2841             $type can be one of the following:
2842             bool (1 bit), byte (8 bit), word (16 bit), dword (32 bit) or string.
2843             $number is the zero-based index into the array of results and takes
2844             the type into account such that $number=0 returns the first byte,
2845             word or dword and $number=1, returns the second.
2846             Booleans are treated the same as bytes and require individual bits
2847             to be extracted separately.
2848             For strings, $number is the offset of the start of the string.

3413             Try to find an ELM module on a COM port.
3414             If $port_details contains the name of a port, start with that one and
3415             work upwards.
3416            
3417             To override the default serial port settings (38400, no parity, 8 data
3418             bits, 1 stop bit, no handshaking), you can pass values in $port_details
3419             in the following format:
3420            
3421             port_name:baud_rate:parity:data_bits:stop_bits:handshake
3422            
3423             e.g.
3424            
3425             $port_details = "/dev/ttyUSB0:115200:none:8:1:none";
3426            
3427             The port name may be left out:
3428            
3429             $port_details = "115200:none:8:1:none";
3430            
3431             It is also ok to just define the port name and/or baud rate and use
3432             default values for parity, data bits, stop bits and handshake:
3433            
3434             $port_details = "/dev/ttyUSB0:115200";
3435             or
3436             $port_details = "115200";
3437            
3438             On Linux you may see the error:
3439             "Can't open /dev/ttyUSB0: Permission denied".
3440             This can be avoided by running as root or by adding your user to the
3441             'dialout' group.

3852             Please report any bugs or feature requests to C, or through
3853             the web interface at L.
3854             I will be notified, and then you'll automatically be notified of progress on your bug as I make changes.
3855            
3856             Please also include a debug trace showing the error so that I can replay your vehicle data and see exactly what you're seeing. This can be done by setting $debug_level in the constructor to 1 and piping the output to a file.
3857             e.g. perl myOBD.pl&>trace.txt
