Hello

Can any one please send me the vhdl code for a state machine that counts up in binary froom 0 to 7 when the control input is a '1' and in a gray code sequence when the control is a '0'

Up sequence is 000,001,010,011,100,101,110,111

Gray Sequence: 000,001,011,111,101,100,110,010


Many thanks

baig

I think the easiest solution would be to internally only count in binary, and only outputting as gray code if requested.
