How connect a rotary encoder

This code enables the connection of a rotary encoder.


CODE: encoder.bas

D0=16:D1=5:D2=4:D3=0:D4=2:D5=14:D6=12:D7=13:D8=15:D9=3:D10=1

count = 0
SW = 5
DT = 4
CLK = 14
pin.mode SW, input, pullup
pin.mode DT, input, pullup
pin.mode CLK, input, pullup


interrupt CLK, encoder
interrupt SW, switch

wait

encoder:
  if pin(CLK) = pin(DT) then count = count - 1 else count = count + 1
  print "count", count
return

switch:
  print "switch", pin(SW)
return
