The situation improved considerably with resistors. I came across the following problem. the E1 sensor pulses were as follows E1 IN 0 pulses and E1 OUT 5 pulses. this after E2 sensors follows E2 in 6 pulses and E2 out 5 pulses. also shows the E1 OUT some pulses. ( <-- WRONG ) but when the E1 sensor pulses were as follows E1 IN 2 pulses and E1 OUT 3 pulses. this after E2 sensors follows E2 in 6 pulses and E2 out 5 pulses. E1 OUT without pulses. ( <-- OK )
how accurate must be for all four sensor pull-up resistor ? because resistors are:
E1 in 2,0K (two series-connected 0,98 )
E1 out 2,3K ( two parallel-connected 4,6 )
E2 out 2,3K ( two parallel-connected 4,6 )
E2 out 2,3K ( two parallel-connected 4,6 )
probably the best would be that everything would be the same 2K or 2,3K...
sensors must act like this:
- E1 only
- E2 only
- E1 and E2
