  3. Error When Driving Counter and DCM Simultaneously

    Sorry, I'm using the papillio one board, so it would be the Spartan 3 guide wouldn't it? Is this the relevant guide? http://www.xilinx.com/support/documentation/user_guides/ug331.pdf
  4. Error When Driving Counter and DCM Simultaneously

    Great, thank you! Given that, my other question I have is: how would I find this out without using the forums? Is there some sort of "clocked resources design guide" or something where I can read more about this?
  5. Hi There, I know 'can you please debug code' posts are generally frowned upon, but I'm having a bit of trouble with what, I think, should be a trivial problem. What I'm trying to do is connect the 32 Mhz clock pin to a counter as well as a DCM, but when I do this, I get the error "Port <CLK> has illegal connections. This port is connected to an input buffer and other components." When I hook the counter or DCM up separate, there is no issue. Can I only have the clock signal going to one location? Is there some sort of signal divider? My main VHDL file is as follows: ibrary IEEE;use IEEE.STD_LOGIC_1164.ALL;use IEEE.STD_LOGIC_UNSIGNED.ALL;entity main is Port ( LED : out STD_LOGIC_VECTOR (7 downto 0); SWITCH : in STD_LOGIC_VECTOR (7 downto 0); CLK : in STD_LOGIC); end main;architecture Behavioral of main issignal counter : STD_LOGIC_VECTOR(29 downto 0);COMPONENT cnt PORT( clock : IN std_logic; total : OUT std_logic_vector(29 downto 0) );END COMPONENT; COMPONENT dcm2 PORT( CLKIN_IN : IN std_logic; CLKFX_OUT : OUT std_logic; CLKIN_IBUFG_OUT : OUT std_logic; CLK0_OUT : OUT std_logic ); END COMPONENT;begin Inst_dcm2: dcm2 PORT MAP( CLKIN_IN => CLK, CLKFX_OUT => open, CLKIN_IBUFG_OUT => open, CLK0_OUT => open ); Inst_cnt: cnt PORT MAP( clock => CLK, total => counter );LED <= COUNTER(29 downto 22);end Behavioral;The counter code is: library IEEE;use IEEE.STD_LOGIC_1164.ALL;use IEEE.STD_LOGIC_UNSIGNED.ALL;entity cnt is Port ( clock : in STD_LOGIC; total : out STD_LOGIC_VECTOR (29 downto 0));end cnt;architecture Behavioral of cnt issignal counter : STD_LOGIC_VECTOR(29 downto 0);beginclkProc : process(clock)begin if rising_edge(clock) then counter <= counter+5; end if; total <= counter;end process;end Behavioral;and the DCM setup is:
  6. Papilio One as High Speed DAQ

    200 Mhz would be perfectly fine for what I'm trying to do. Can you recommend any tutorial about how to accept commands from a UART? I've followed this tutorial: but it doesn't really explain how to send different types of data down the UART. Best Wishes. -TP
  7. Papilio One as High Speed DAQ

    Hello, I just bought a papilio one and logic start shield, and I'd like to use these as a high-speed data acquisition device. I'd like it to count pulses sent to it via an external pulse generator, then when it receives some sort of command from a computer, transmit to the computer how many pulses it had received since the last transmission request. I was hoping an experienced user could tell me how they would approach this problem. Best wishs, -TP
  8. Papilio One 500k - Speed Grade 4C

    Great! Thank you for your concise and informative answer!
  9. Hello, I have a Papilio One 500k, and I see on the chip, it is marked with a 4C speed grade. Now, does this correspond with the speed setting in the xilinx ise? What happens if I choose -5 instead of -4? Also, what does the 'C' refer to? I don't see any 'C' in the new project wizard's settings.
