VHDL dual 7-segment display controller
$0
This VHDL module shows a decimal value from 0 to 99 on the Pmod SSD: Seven-segment Display from Digilent or similar dual 7-segment display.
Description
The seg7.vhd module displays a number from 0 to 99 on the Pmod SSD: Seven-segment Display from Digilent or similar. The Pmod SSD can only illuminate one digit at a time, but by quickly alternating between the two, the numbers will appear as static to the human eye.
The refresh rate is configurable through generics.
Entity
entity seg7 is
generic (
-- refresh_hz = (2 ** clk_cnt_bits) / clk_hz
clk_cnt_bits : integer
);
port (
clk : in std_logic;
rst : in std_logic;
value : in integer range 0 to 99;
segments : out std_logic_vector(6 downto 0);
digit_sel : out std_logic
);
end seg7;
