Rover 5 Infrared Code Processing Notes

Infrared Codes Auto-Generated Array Declaration and Comments

Below is an example of my program's auto-generation of the Array Declaration (and comments ) which stores the pattern produced by pushing my toy Remote Control's Power button, showing both the index# of each pulse, and whether it is Long or Short.

In an ideal world, I'd represent the pulse chains as hex bits, where a Long pulse represents 0b1, and a Short pulse represents 0b0.

But I wasn't sure how may stop- and start-bits are in these chains, so I just stored them as counts of Long and Short pulses instead:

// For brevity, I'll express each button's pattern as pairs of:
//    Long pulses, Short pulses.
// -1's = placeholders, to ensure Long-followed-by-Short order,
// for when there is no Short pulse preceeding a Gap, etc.
// -2's = a Short pulse comes first after this Gap, rather than a Long one.
//
int toyPowerButtonPattern[] =

// We want to start at index 1, to match the output of the
// rawirdecode program. so let's put this spot to good use,
// to store our command name.
