  1. Hello everyone,, I bought a Logic Start Megawing from your store. I would like to program the 4 of the seven-segment display to 4 unique digits to display a number such as 1234. Do you have some of the document which I can use? Also for the anode หมวกกันน็อค AN0, AN1,AN2 and AN3, If I map them, could you give me the addresses.  Thanks,.
  2. Hello everyone,, Just wanted to let everyone know that I will be heading out tomorrow to work from China for a while! I was lucky enough to be invited to a Chinese-American Maker Competition in Beijing. I didn't want to say anything before now mil thickness tester because it was a little bit up in the air but everything is finalized now and I'm getting on a plane tomorrow morning! For the next week it may be difficult to get online behind the Great Firewall of China but I will do my best to be responsive. After the Maker competition I will be heading to Shenzhen to work on the Papilio DUO for 1-3 weeks. Please watch the Gadget Factory blog where I will do my best to share pictures and info about the trip!
  3. Hello everyone,, I am working my way through the IntroToSpartanFPGABook. And i was stuck in Chapter 20 for about half a day. My problem was that i just could not get the "Z" to appear on my serial port. Which was strange, because with a lot of the other bitfiles i found on this site there was serial data when I did a "cat /dev/ttyUSB1" so I know it wasn't a problem with the board, or with linux (x86_64), or anything other than my own VHDL code. Unfortunately i assumed that the serial port would hazard perception test be programmed correctly, but it was not. I had to do a "stty -F /dev/ttyUSB1 raw", because it was still in the "XON/XOFF" protocol apparently. I tried to put as much search terms I used in the past day in this message to hope that someone with the same problem will manage to find it. So now a have a screen full of "Z". On to the next objective, somehow encode the state of the switches into the serial data. Lots of fun. Edit: This was on a Papilio Pro. But the same would've probably happened on a One..

    I2C core with Zpuino

    Hello everyone, I came across this page the other day describing how to add an I2C core to the Zpuino. Unfortunately, I am very new to FPGAs and VHDL and really have no idea how to put this to use. Could someone point me in the correct direction ufa? As I understand it, I must add the 3 vhdl files to my zpuino project, edit papilio_top.vhdl and add a component called 'i2c_master_top', add the i2c_master_top to one of the wishbone slots, and then finally add the pps stuff at the end? Is this correct? Sorry for the lack of proper terms, as I said I am very new to this. Thanks in advance for any help that anyone can offer.

    Xilinx WebTalk

    Hello everyone,, (this post has nothing to do with Papilio. Papilio is great) I dislike WebTalk. Real or imaginary, it seems evil. So, I was thinking of using Ubuntu's wubi to create a little Linux partition. Should Xilinx ISE work OK there compared to a Windows 7 environment (maybe Ubuntu 12.04 or 14.04)? It will probably have around 20 gigs of free space. I read that you can thwart webtalk under Linux. Don't know if that is fair. But I don't want stuff mucking around in the background taking notes and pictures and sending a lump off to someone for something near me cheap color copies. And really Mr. Xilinx this medieval thinking is "all good" on the way up, but what if you need people on the way down, or when we have a little more choice? I suppose the MCU market is very different than FPGA realated stuff, but there are a lot more high quality free toolsuites for MCU development nowadays. And another thing .... the basic idea of free dev tools is that we the developers, free of charge, will be more inclinded to spec Xilinx chips in our design when we use a spyware_and_$ free develeopment tool from a friendly company. Do you really learn that much from a bunch of students who are learning FPGA? Hmm. Can't imagine it would be about design, but anyway. And if you see a need for free anything, why stuff webtalk in there? Tell the bean counters you are thinking long term, like a champion. BTW the chips are truely amazing & I think some appreciate that Xilinx is at least informing us about webtalk..

    Pmod Connector

    Hello everyone,, Initially when the Kickstarter campaign started Jack said he was able to squeeze a Pmod connector onto the Papilio Duo PCB. Did a Pmod connector make it into the final version of the PCB? If not any suggestions on how to connect a cheap color copies by 55printing Pmod device to a Papolio Duo? Wanheda..
  7. I'm a first time viewer and poster today, googled the subreddit for some help. Yesterday I was out on my 11ft aluminum boat fishing, when I went to load the boat back into my truck I took the battery out of the boat and put it in the truck bed to make Deep Cycle Battery for Boat the back end of the boat lighter, loaded up and drove off. Didn't notice that I lost my battery until about 20 minutes later when I got home to charge it up. Drove back another 20 minutes to the lake looking for it on the highway only to find it submerged underwater at the boat launch. The battery is a 27 series deep cycle, I'm sure it's a vented but sealed battery, the positive terminal had coloured the water around it by the time I got back. I charged it overnight and my charger says its at full charge, should I be worried about anything?
  8. Hello everyone,, i have question about Papilio Pro Does this board support US distance calculator matlab (system generaor) and does it have MicroBlaze Processor my regards..

    JTAG Logic Analyzer

    Hello everyone,, Ok, I went down the rabbit hole and am just now coming up for breath! After an epic week long battle that found me obsessed with this one task I have something pretty cool working on the Papilio. Let me start from the beginning, at the end of last week when I was working on the new board design I realized that there might be a huge problem with trying to connect the channel A UART pins from the FT2232 to FPGA I/O pins. I pulled out the trusty Papilio One and tested it out, sure enough, when the Papilio is being programmed all of the I/O pins go to 3.3V which will interfere with the TCK and TDO pins during jtag programming. So the way I had things wired up was not going to work. I started thinking about solutions, adding an IO switch would solve the problem but I'm not super thrilled about doing so. So I started thinking about why we need it connected and it really comes down to being able to use channel A for communications after the FPGA is programmed. Well, we already have an example of doing that, we use the bscan primitive to program SPI Flash... app marketing strategy So I thought, well before I commit to adding an IO switch to the board I should spend a couple days connecting the Sump Logic Analyzer to the bscan primitive so we can use the FT2232 channel A or logic analyzer debugging and use channel B for normal uart communications to our Soft Processor. It's going to be hard to do but I should be able to bang it out in a couple days... Famous last thoughts... Every day I made just enough progress to keep me completely obsessed for the next day, just a little bit more and it will be working... Well it dragged on way longer then I expected but I have a first working prototype! There are still some bugs to squash but it is working well enough to prove that we can use channel A for debugging and there is no need to add an IO switch to the new board
