Hi phill99, I have had trouble getting this to work with an Onkyo receiver. The earlier NECSub on a micromite worked perfectly to control all functions. Using a digital CRO There was a long pulse just after the start of the final bit of the output IR pulses. The final bit was a logical 1 and the long pulse occured before the completion of the total time. This was not present on the micromite output.
After some experimenting I found that changing c(66)=1 to C(66)=8 moved the long pulse later and the Onkyo could be controlled.
Your later version "Cleaned the sub up a bit and removed debug prints." shows the same long pulse at at the end, and is not recognised by the Onkyo. Is there a way to adjust this version?
