Hi,
Can any1 help me out interfacin LED matrix with the UP3 board. There was a board provided by altera cubic cyclonium board which had LED matrix interface with it so can any1 please get me that verilog code. Thanx in advance.Link Copied

This is the code that was supplied with the Cubic Cyclonium (LED matrix driver) in a hardware tutorial class. Very simple, just copies the bit across the whole row. For example, if LEDS(0) is high, it turns on the entire top row of the LED matrix.
library ieee; use ieee.std_logic_1164.all; use ieee.numeric_std.all; entity LED_DRIVER is port ( clock : IN std_logic; resetN : IN std_logic; LEDS : IN std_logic_vector(7 downto 0); LED_MATRIX : OUT std_logic_vector(28 downto 0) ); END LED_DRIVER; architecture rtl of LED_DRIVER is SIGNAL COUNTER : unsigned(15 downto 0); SIGNAL SCANNER : unsigned(20 downto 0); BEGIN LED_MATRIX(28 downto 8) <= std_logic_vector(SCANNER); LED_MATRIX(7 downto 0) <= NOT LEDS; process(clock,resetN) begin if resetN = '0' then COUNTER <= (others => '0'); SCANNER <= to_unsigned(1,21); elsif clock = '1' and clock'event then COUNTER <= COUNTER + 1; if COUNTER = to_unsigned(0,16) then SCANNER(20 downto 1) <= SCANNER(19 downto 0); SCANNER(0) <= SCANNER(20); else SCANNER <= SCANNER; end if; end if; end process; END rtl;- Mark as New

Thanx man,this will surely get me out of the hell.
This is for stationary display can u please get me code for scrolling display. Refrence verilog code will also do of even 5X7 LED matrix.(Not necessary to be of cubic cyclonium ). I wud be glad to get logic from u. Thanx in advance.- Mark as New

Sorry, thats all I have. I got this from a set of files used for a hardware tutorial.
This is just a guess, but I'd say the scolling display was driven from a NIOS (soft processor) inside the FPGA along with the driver I sent you. - good luck
