lut5 is quite useful - I rather use that than gobs of and,or and not here's a trivial script to make it a bit easier to use: http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Lut5
given a boolean expression of inputs, it will create truth table and function value ready to paste into a HAL file. Example: 1-out-of-2 mux: $ python lut5.py -n3 '(i2 and i1) or (not i2 and i0)' # expression = (i2 and i1) or (not i2 and i0) #in: i4 i3 i2 i1 i0 out weight # 0: 0 0 0 0 0 0 # 1: 0 0 0 0 1 1 0x2 # 2: 0 0 0 1 0 0 # 3: 0 0 0 1 1 1 0x8 # 4: 0 0 1 0 0 0 # 5: 0 0 1 0 1 0 # 6: 0 0 1 1 0 1 0x40 # 7: 0 0 1 1 1 1 0x80 # setp lut5.N.function 0xca -Michael ------------------------------------------------------------------------------ All the data continuously generated in your IT infrastructure contains a definitive record of customers, application performance, security threats, fraudulent activity and more.
