  1. Hello, Does PmodSD (https://reference.digilentinc.com/reference/pmod/pmodsd/reference-manual) support SD mode of operation? Is it designed only to work with SPI mode as written in the reference manual? Please let me know Regards, Vinay Shenoy
  2. Turn your Nexys Video board into something useful for hardware development by adding the IO capabilities of another FPGA board. In this project the other board is a Digilent Spartan 3A Starter board. But it has a lot of resources that make it useful for a variety of projects needing an FPGA. The "magic" is supplied by those wonderful Ethernet PHY modems. Release 3 offers two target boards, Gigabit and 100 Mbps designs. Check it out even if all you want to do is connect any two FPGA boards with Ethernet capability. IO_EXPANDER_R3.zip
  3. Hello. I recently bought a Digilent Arty FPGA dev board. I need to connect some 8-bit or 16-bit SRAM chips to the board and I have to determine what the best method would be, to bring out the ( 40, I believe ) data lines on the four 6x2-pin Pmod connectors on the side of the Arty and connect them to a solderless breadboard, preferably without any soldering involved in this process at all. I need access to the Arty's LEDs and buttons on the top so I don't really want to go with a stackable Arduino shield, which requires much soldering to attach a solderless breadboard, at least, soldering is required for the Arduino shields that I've seen. Well, after thinking about my problem and the requirements for the SRAM chips in my design, I thought of a way to easily connect my Arty to any old breadboard. I plan on buying a few Pmod extender cables, some Pmod 2x6 pin headers / gender-changers and some 12-pin Pmod to DIP adapters. I could plug two or three Pmod extension cables into my Arty, plug 6x2-pin DIP connectors onto the ends of the cables and then plug the cables into a breadboard of my choice. I've made up a list of things I'd need to buy from Digilent and I think that I need a few of these : http://store.digilentinc.com/2x6-pin-cable/ , this : http://store.digilentinc.com/2x6-pin-header-5-pack/ , a few of these : http://store.digilentinc.com/pmod-dip-dip-to-12-pin-pmod-adapter/ and finally just any solderless breadboard. I'm wondering if this is the easiest method with which one access all of the data GPIO lines exported by the FPGA via my Arty's Pmod connectors -- if I've missed something obvious or this question seems stupid, then please forgive me. Any suggestions or advice would be appreciated, Thanks, jdb2
