=head1 DESCRIPTION |
21
|
|
|
|
|
|
|
|
22
|
|
|
|
|
|
|
Slink-e is a product that can speak to many different Sony products over |
23
|
|
|
|
|
|
|
the S-Link port. Also, it can receive and transmit infrared signals over |
24
|
|
|
|
|
|
|
8 different transmitters/receivers. |
25
|
|
|
|
|
|
|
|
26
|
|
|
|
|
|
|
For now, the bulk of this code deals with the transmission and reception |
27
|
|
|
|
|
|
|
of these infrared signals. |
28
|
|
|
|
|
|
|
|
29
|
|
|
|
|
|
|
Note that this code borrows heavily from C++ code from Colby Boles. In |
30
|
|
|
|
|
|
|
fact, sometimes I just copied his code and comments verbatim. |

This returns the infrared sampling period of the Slink-e. Values can |

The IR sampling period determines the maximum timing resolution which |
815

|
|
|
|
|
|
can be achieved when decoding IR signals. In general, the sampling |
816
|

period should be at least 3 times shorter than the shortest pulse you |
817
|
|
|

|
wish to detect. Short sampling periods are necessary when acquiring |
818
|
|
|
|
|
|
|
timing information about new remote signals, but are not necessarily |
819
|
|
|
|
|
|
|
need to output known remote signals since the sampling period need only |
820
|
|
|
|
|
|
|
be the least common multiple of the pulse widths in the signal. |
821
|
|
|
|
|
|
|
|
822
|
|

The IR sampling period is also used as a timebase for parallel port |
823

output signals. |

The IR sampling period determines the maximum timing resolution which |
849
|
|
|
|
|
|
|
can be achieved when decoding IR signals. In general, the sampling |
850
|
|
|
|
|
|
|
period should be at least 3 times shorter than the shortest pulse you |
851
|
|
|
|
|
|
|
wish to detect. Short sampling periods are necessary when acquiring |
852
|
|
|
|
|
|
|
timing information about new remote signals, but are not necessarily |
853
|
|
|
|
|
|
|
need to output known remote signals since the sampling period need only |
854
|
|
|
|
|
|
|
be the least common multiple of the pulse widths in the signal. |
855
|
|
|
|
|
|
|
|
856
|
|
|
|
|
|
|
The IR sampling period is also used as a timebase for parallel port |
857
|
|
|
|
|
|
|
output signals. |

This set the length of the shortest IR receive message in bytes which |

|
will be considered a valid message. IR receiver modules such as the one |
1109

|
on the Slink-e tend to be very sensitive to both optical and electrical |
1110
|

|
|
|
|
|
noise, causing them to occasionally generate false pulses when there is |
1111
|
|
|
|
|
|
|
no actual IR signal. The false pulses are generally of short duration |
1112
|
|
|
|
|
|
|
and do not contain the large number of on/off alternations present in a |
1113
|
|
|
|
|
|
|
true IR remote signal. By setting a minimum message length, false pulses |
1114
|
|
|
|
|
|
|
will be ignored and not reported to the host. The minimum length can |
1115
|
|

|
range from 0 to 15 bytes. |
1116

|
|
typically the last five bytes of the data array. This is an array |
