| Alchitry Io Switches with Au |

After trying to get the switches (DIP and pushbutton) Alchitry Io working for a little too long it finally occurred to me that pulldowns need to be enabled for each of the pins attached to a switch. If pulldowns are not enabled the pin will typically float high. The pulldown resistor can be enabled on a pin by pin basis in the constraints file as follows:
Code: set_property PACKAGE_PIN C4 [get_ports {dip_sw[0]}]
set_property IOSTANDARD LVCMOS33 [get_ports {dip_sw[0]}]
set_property PULLDOWN TRUE [get_ports {dip_sw[0]}]

| Clocking with Lattice Parts |

Hey,
So with the Mojo, the way to get new clocks was to use coregen via the awesome installed button. Since Cu is a Lattice part there is obviously not a coregen option. Therefore, how do I get my higher or lower clock signal?

Hey,
So I've had the Alchitry Cu for a few days. Great looking board, I'm excited to get the software up and running. Just one question. How do I connect anything to it? I don't see my comfortable headers and I feel completely paralyzed.
Objectively, I know there is a solution to this problem and that it wouldn't require too much work on my part, but is there a simple solution to go from the super whamadine headers to my comfortable breadboard friendly ones?
(P.S. I don't hate the new headers, my Mojo has so many bent pins it's starting to look like a porcupine.)

Welcome to the new forum! After the old forum was basically made useless by an overflow of spam, this new one will hopefully fare better.
Note that you will need seperate logins for the forum and our store.
You can still access the old forum in its "read only" state here https://forum.embeddedmicro.com/
