1-the pulses that come from the EGIS engine through an ULN2001 (open collector) the amplitude is not 24V, it depends on the + pull-up resistor, I checked it in real. the current flowing through the opto is limited by R470ohm and diode 1n4148 (10mA).
2- in my first test I had kept the two pulses (A and
and obtained more pulses, but counting only the high state we have 18000 pulses for 180°, if we count high and low state 36000 pulses for 180 ° and with a mix of two pulses (A and
72000 pulses for 180°.
In the EGIS documentation it is written that there are 100 pulses per degree. It's too much, the definition is far superior to the mechanical game.
3- nothing to say!!
4-it is not a classic 7805 but a compatible module but switching mode, no heating, 95% efficiency.
for information i add schematic of my first test , good for a incremental encoder like omron E6B2-CWZ6C. but not useful for egis .
I like your project, I am more comfortable with assembly language programming.
