I am working on a metal detector at the moment but cant figure out how
to implement it my VHDL code.
1 | ENTITY sensor IS
|
2 | port ( metaldetector : in std_logic;
|
3 | metal : out std_logic;
|
4 | );
|
5 | END ENTITY sensor;
|
As long as there isnt any metal close to the sensor 'metaldetector' gets
pulses on a 6.1kHz frequency. So as long as the 'metaldetector' keeps
getting pulses the out port 'metal' should be '0'.
When there is a pulse missing (or multiple pulses) 'metal' should become
'1' until the next pulse.
It shouldnt be that hard to make a code that can do that, but i just
cant figure it out. Any help would realy be great!
