Hi, jet
Pulsin seems to be very adequate ...
@ 4 Mhz result will be ~100 to ~ 200 ...
100 is 0% 200 is 100% ...
@ 20 Mhz ...............~ 500 to ~ 1000
then just calculate the y = ax+b equation ...
But if you want to have precise 0% for stick down and 100% for stick up , you'll have to calibrate and memorize result first.
i.e 112 is 0 % and 188 is 100% @ 4Mhz
May be you will have to use DIV32 for calibration if 20 Mhz necessary for 2µs resolution ( see manual ...)

Hi, jet
I Think the best for you could be to learn the Melabs or Parallax Basic manuals from the beginning.
Jet models will have to wait some time ...
