IR Counter

[dhouston]

Also, since the array elements are reset to zero at the top of the loop, you can simplify this...

            if (PULSE_LENGTH > 90) then 
                RF.0(i) = 1
            else
                rf.0(i) = 0
            endif

to this...

            if (PULSE_LENGTH > 90) then 
                RF.0(i) = 1
            endif

And, while errors are less likely with IR, you can detect them buy adding RF[2] and RF[3]. They should always sum to 255 or $FF.
