Problem never to be solved?

I suppose that we dealing here with logic systems, where a halfway level does not exist.
Any results from your investigation?

Perhaps our problem is that Manchester encoded signals look different on a data line (no DC component) than on the output of an IR receiver (idle = 5V).

Manchester serial decoding does not work for the output signal from my TSOP33436 IR receiver (RC5 protocol). Instead of positioning the first bit at the first transition (which is from +5V to 0) it does so at the second transition. The results are wrong packet length (13 bit instread of 14) and wron...

A really nice feature would be the possibility to use parameters in math channel formulas. This should not be too difficult to implement.
