  1. hamster tutorial help

    Hello. Im able to download pre made bitfiles to my Papilio Pro + LogicStart using the bitloader, and DesignLab, however, Im running into a problem trying to create a simple vhdl example from the hamster fpga ebook. Specifically, Im at section 6.4 "Downloading the Design Into the Device." Do I select FPGA or SPI Flash to download to? The screen-shot seems to imply FPGA. At any rate, the Switches_LEDs project fails to operate on the physical board as I expect. Instead when I download to SPI, 3 of the digits show "8" while one is blank. The LEDs are all off, and the switches have no effect. I did make the following changes from the tutorial for the Pro board: I set device to Spartan6 xc6slx9 tqg144 speed -2 And the constraints file is: # Constraints for Papilio Pro NET switch_1 LOC = "P120" | IOSTANDARD=LVTTL; ; #pap1 was switch (6) p3 NET switch_0 LOC = "P121" | IOSTANDARD=LVTTL; #pap1 was switch(7) p4 NET LED_1 LOC = "P133" | IOSTANDARD=LVTTL; #pap1 was led(6) p16 NET LED_0 LOC = "P134" | IOSTANDARD=LVTTL; #pap1 was led(7) p17 Above changes based on pinout chart: http://papilio.cc/index.php?n=Playground.PapilioPinouts Bit stuck for ideas, any help appreciated. Thanks.
  2. Hello. I recently got around to diving into a Papilio Pro I received about 3 years ago. I struggled through the Windows 10 issues with the missing port/usb detection and the Windows 7 Web Pack ISE crashes. Im now able to download the Papilio Pro 'hello world' bit file example, and confirms it dumps a default ascii table to a virtual COM port. I then downloaded DesignLab, but notice there's no Papilio Pro board (just the Papilo Pro / ZPUino ?) So I think Im out of luck there. I also have a LogicStart mega wing, and was hoping there was some simple precompiled bit file I could download and verify its working properly. Does such a thing exist, or do I have to manually create one with the Xilinx ISE and clips Hamsters fpga ebook? Thanks very much, Rob.

    Okay the first line of my ucf file I had: NET switch_1 LOC = "P120" | IOSTANDARD=LVTTL; ; #pap1 was switch (6) p3 instead of NET switch_1 LOC = "P120" | IOSTANDARD=LVTTL; #pap1 was switch (6) p3 The double "; ;" was causing a syntax error I didn't notice. I was actually downloading the previous bit file unknowingly. Downloading to SPI Flash, leaves everything working! -Rob
  4. Path of least resistance for beginner..

    Sorry, for anyone following, finally got it working. Had to select a sketch that supported both the Papilio Pro *and* the LogicStart. "MegaWing_Logicstart" was the one. That's great. Now I'll start working on some actual vhdl in the ISE. Cheers

    Alright, so after writing this, I suspected I have to upload the ZPUino image , which this thread seems to say. I'l dig around that area.
