  1. All good. Thank you for your help, key was to stop looking at hardware.
  2. Following text from the Arduino page, "The Arduino Leonardo board uses Serial1 to communicate via TTL (5V) serial on pins 0 (RX) and 1 (TX). Serial is reserved for USB CDC communication. For more information, refer to the Leonardo getting started page and hardware page. " I replaced Serial with Serial1 and the Tx pin began sending the serial data.
  3. The Papilio Duo AVR is model after the Leonardo so Serial1 is the communication instance which the Tx pin is associated. Text below is off the Arduino site.

  4. I agree, The IDE may not be handeling the Serial hardware correctly...
  5. Blink will toggle Pin1 (Tx).
  6. I removed the bootloader and replaced it on the AVR. Using the "The Offical Papilio Duo Pinout Diagram" I did not see the I2C pins and defaulted to use F7, F6 then to B1, B3. Looking at the silk screen on the Papilio Duo, I used D0 (SCK), D1(SDA), the I2C device began being programmed/working. Still I have no Serial Output. Blink will toggle Pin 1 (Tx)

  8. I've been able to get the pins 2-13 to toggle by loading the AVR via the ISP connection from the FPGA, however, the TX and SCK, SDA pins are working correctly. Any suggestions?
  9. I removed Windows from my machine and loaded Ubuntu and (re)loaded DesighLab working now.
  10. I cannot get the AVR to control the TX pin. I want to use the serial out but no data is being sent out TX. In the Loop section, I get the OK on the monitor, and have the LED blinking, but pin 1 (TX) does not toggle. What might I be missing? Thanks you for your help...

  11. Yes, I've been there. Most of the videos seen to assume level of understanding which I don't have. Example "Open Project" familiar term but not specific enough for newbie, plus what I fumble and find looks nothing like video...
  12. My condolence on the passing of your grandfather... I so new to this that I've only have loaded DesignLab fumbled thru getting Xilinx loaded and security enabled (I think), and began to try following yourvYouTube videos. However, very little resembles the examples. The DesignLab is the same ant menu items. But the file within directories are not even close to what your video is requesting I click on. My installation is in the weeds for some reason. My laptop is running a Vista 64bit.
  13. Following along with YouTube I'm not running into the files mentioned in the video.
