This Forum is Dedicated For all The Object Oriented PIC Lovers .......... The concept behind OOPic is straight forward. Use preprogrammed multitasking Objects from a library of highly optimized Objects to do all the work of interacting with the hardware. Then write small scripts in Basic, C, or Java syntax styles to control the Objects. During operation, the Objects run continuously and simultaneously in the background while the scripts run in the foreground telling the objects what to do.

This object (and oRCin(1-6)X) use the hardware timer inputs. You can
use one or both (IOLines 16 and 17). Check for references to oRCin(1-
6)X.

The object is expecting a pulse train from the receiver BEFORE it is
demultiplexed. This will be a series of up to 6 pulses in a window
20 mS wide. Since each pulse must be < about 2 mS and for 6 pulses
that would use about 12 mS then the 8 mS gap is what synchronizes the
train. It will work even if the individual pulses are up to 2.5 mS
wide (5 mS gap is still twice as long as a pulse window).
