Hello,
Iam trying to interface the ADA board with my cyclone 3 starter kit. I want to view my led output on the oscilloscope. So i have identified the HSMC connections . I can track the signals on my ADA board at the D/A chip pins using my multimeter but the chip output IOUT A does not show any variation. It is stable at a particular voltage.
this is my code entity: and its corresponding assignments:
Clk : in std_logic;
--led_cathode : out std_logic;
--hsmclk_ou std_logic;
--da_mode,da_wrta,da_da7ut std_logic;
DAC_MODEut std_logic;
DAC_CLK_A,DAC_CLK_But std_logic;
DAC_WRT_A,DAC_WRT_But std_logic;
ouut std_logic;
k: out std_logic_vector(1 to 4);
OSC_SMA_ADC4:in std_logic ;
SMA_DAC4:in std_logic ;
poweron: out std_logic
architecture ar of testing is
constant max_count : natural := 40;
constant m_count : natural := 50000000 ;
signal Rst_n : std_logic;
signal q:std_logic_vector(1 to 4):="0001";
signal led_anode:std_logic;
signal clk_1,clk_2:std_logic:='0';
begin
-- my dac configurations, now ill show u the pin assignments
DAC_CLK_A <=clk_2;
DAC_CLK_B<=clk_2;
DAC_MODE<='1';-- dual mode
DAC_WRT_A<=clk_1;
DAC_WRT_B<=clk_1;
poweron<='0';
Thanks in advance!
