jammasterz Posted September 19, 2014 Report Share Posted September 19, 2014 Hey there. I hope this is the right tab for this type of question. I just got my Papilio Pro V1.3 along with LogicStart wing V1.2. This is the very first time I play with a FPGA. I follow a tutorial in which I'm told to upload this program:library IEEE;use IEEE.STD_LOGIC_1164.ALL;entity Swiches_LEDs is Port ( switch_0 : in STD_LOGIC; switch_1 : in STD_LOGIC; LED_0 : out STD_LOGIC; LED_1 : out STD_LOGIC);end Swiches_LEDs;architecture Behavioral of Swiches_LEDs isbegin LED_0 <= switch_0; LED_1 <= switch_1;end Behavioral; Pretty basic. Then I created a constraint file, that I modified a little so that the pin numbers are correct for Papilio Pro (tutorial is written for One):# Constraints for Papilio Pro NET switch_1 LOC = "P120" | IOSTANDARD=LVTTL; NET switch_0 LOC = "P121" | IOSTANDARD=LVTTL; NET LED_1 LOC = "P133" | IOSTANDARD=LVTTL; NET LED_0 LOC = "P134" | IOSTANDARD=LVTTL;Then I find the bin file and launch it(yes I have papilio loader installed with all the drivers). I see that the RX and TX diodes are blinking(for about a minute or 2). But then the program doesn't work. The switches don't affect the LEDs at all, and there are some random LEDs that are blinking, and sometimes 2 segments from the built in 7seg blink along with the diodes. I have no idea what I've done wrong. Quote Link to comment Share on other sites More sharing options...
