need help, retriggerable one-shot

[skipperdodle]

Hello all,

I'm trying to create different delays (retriggerable one-shots) in which the inputs are a trigger input and an 8Hz clock. If you could help me work out how to create this and get an output of a 10 second HIGH pulse I would appreciate it and I'm sure the other delays would come naturally.

Thanks, Skipper

found the answer:

Process(clock, trigger)
variable count: integer range 0 to 9;
begin
if rising_edge(clock) then
if trigger = '0' then
count := 0;
output <= '1';
elsif (count = 9) then
output <= '0';
else
count := count + 1;
end if;
end if;
end process;
