Geetings all; wordwrap off, long lines ahead. Trying to get a handle on too much code for an r-pi, I expunged several modules and have attempted to incorporate their functions into a lut5.
Several places its worked well where all the data paths were forward. But in trying to setup a oneshot, called 'time(axis letter)' I cannot make it work. Its as the function string is wrong. The code: # first, an and2 to detect & make a 25% duty cycle signal from turning the dial net xAtoggle <= hm2_[HOSTMOT2](BOARD).0.encoder.01.input-a => and2xtoggle.in0 net xBtoggle <= hm2_[HOSTMOT2](BOARD).0.encoder.01.input-b => and2xtoggle.in1 net xtoggleout <= and2xtoggle.out # want falling edge! # now I have, at xtoggleout, a nominally 25% duty cycle high, pulse, we trigger on rising edge # now collect button status and make initial trigger pulse out of it on rising edge. net buttonxdown <= hm2_[HOSTMOT2](BOARD).0.gpio.066.in => edgextrig.in setp edgextrig.in-edge false setp edgextrig.out-width-ns 10000 net xtrig0 <= edgextrig.out => or2xretrig.in1 # true pulse when released ###################################### # set up the oneshot for dial timeout ###################################### setp timex.rising true #default setp timex.falling false #default setp timex.width 3.0 # setup a lut5 to retrigger timex or timez setp lut5timex.function 0x80 # 5 input gate using 3, 0 inverted net xtoggleout => lut5timex.in-0 # string of + pulses as dial turns net buttonxdown => lut5timex.in-1 # true when released net xtimedout <= timex.out => lut5timex.in-2 # true while oneshot running, kills retrig path when timed out net buttontimex <= lut5timex.out # => or2xretrig.in0 # s/b train of + pulses, retriggers on rising edge net xretrigger <= or2xretrig.out => timex.in # combined initial + pulse trigger to retrigger timex lut5timex.out remains silent, timex is triggered once by the edge.out -> or2.in1, or2.out ->timex.in path, when the button is released. The idea is to trigger the oneshot on release of the button near the dial, and keep it triggered until the dial has been motionless for 3 seconds. The oneshot times out, lut5timex.in-2 goes false and this can only be restarted by pressing and releasing the button again. What have I done wrong? Thank you.
