  tutuorial for AU with vilvado
Posted by: aaronf30 - 04-24-2019, 02:51 PM - Forum: General Questions - Replies (2)

Is there any simple tutorial for the AU with vilvado. It all seems to be outdated tutorials for old projects.


  Layout blank for breakout board
Posted by: prebys - 04-23-2019, 07:53 PM - Forum: General Questions - Replies (3)

I'm considering designing a custom breakout board for the Au for an undergraduate lab application.  Is there there a blank layout (in some standard format) that I can use as a starting point?


  Alchitry CU Constraints
Posted by: kebo - 04-22-2019, 08:11 PM - Forum: General Questions - Replies (4)

Hello All,

I finally got some time to try out my Alchitry CU board. I worked trough the first couple of Verilog tutorials with Alchitry Lab and everything worked fine so far. Now I'm really stuck with the constraints...How can I assign custom pins rather the ones provided with the alchitry.acf file or how do I now what name all the pins have? Is there a description for that ? What I basically want to do is to declare some new outputs and inputs besides the LEDs in the default .acf file using the Alchitry CU with the Alchitry Br shield. Thanks in advance!

Cheers,
Kevin


Question Au: Store a few bytes between power cycles
Posted by: David - 04-22-2019, 09:32 AM - Forum: General Questions - No Replies

Using the Au without additional hardware, is there any way to store a few bytes of data from lucid/verilog code, which can then be read back after a power cycle?

I would like to write a few bytes of data from the lucid/verilog design to eeprom/flash storage and be able to read them back again after a power off/power on.

The Au has eeprom for the ftdi and flash for the fpga. Is there any way of using any extra space, which might be available, from the fpga?


Thanks,

David


  AU not recognized by loader
Posted by: befedo - 04-20-2019, 09:03 AM - Forum: General Questions - No Replies

Hi there,

I've copied the UDEV rules and ran the loader CLI under tools with './loader -l' and got:

Code:
Devices:
 0: Alchitry Au
 1: Unknown

lookig at dmesg it shows:
Code:

[  941.608693] ftdi_sio ttyUSB1: FTDI USB Serial Device converter now disconnected from ttyUSB1
[  941.608711] ftdi_sio 2-2:1.1: device disconnected

What am I missing? And how can I find any missconfiguration?

Thanks for your time and best regards,
befedo

Could be ignored ...

I've got lost somewhere between reloading UDEV rules and reading carefully the output of the loader CLI.

  Board Drawings
Posted by: MyDirtIsRed - 04-17-2019, 08:04 PM - Forum: General Questions - No Replies

Hello,

Is there a place where we can find either:

-Mechanical drawings of the various boards (I personally would like to see them for Au and Io, but I presume others would want the drawings for the other boards as well)?
-Generic library files (or library files in other formats besides Eagle)?
-A board outline file, with connector placements, maybe in DXF format?

The gist of this being making it as easy as possible for the community to make their own shields to attach to, e.g., the Au board.

If some or all of this already exists, and I'm unaware, I apologize in advance.

Slainte!

  Mojo V3 General Question
Posted by: jsanchez1996 - 04-15-2019, 04:54 PM - Forum: General Questions - Replies (2)

I wanted to know what the max current for the pins of the Mojo V3, I read the Spartan V6 spec. sheet and said it had a max current of 24 mA. Another question if I want to add a delay to a line of code using verilog 

example 

 #10 x =  1; 

will this work with the Mojo V3.


  Understanding I/O
Posted by: Holoptics - 04-14-2019, 04:07 PM - Forum: General Questions - Replies (5)

Sorry for the # of questions i'm about to have, but I am not very experienced in electronics and the guy I've been trusting to help on this has been really busy and hasn't read most of the documentation yet. For context; I am working on what is essentially a MIDI keyboard & I want it to have the ability to have variable volume. Based on how this piano will be made, I thought the best way to do this was to take in a signal for each key and measure how long the "note on" signal is recieved in comparison to the base clock. However, based on what I can tell I only have 59 single I/O pins and enough differential I/O pins to take in 9 extra signals (68 signals in total) which is less than the 88 signals I need. So here come the questions.

1. Can I run different I/O types on the same bank?

2. What is this Dual Voltage I/O and how does it work? (Can't find any documentation)

3. What is the Voltage coming out of the LED pins? (Might use them as a way to make out MIDI output)

We have till Saturday morning to get this project done so any help would be really appreciated


  Max register/memory size?
Posted by: Keith - 04-11-2019, 07:00 AM - Forum: General Questions - No Replies

Hi,

I'd like to buffer about 6-8 KB on a FPGA board. Is that possible with either the Alchitry Au, Cu, or older Mojo board (I have a Mojo board currently)? For example, would I just create a register with the corresponding number of bits? Or is there some onboard memory on the FPGA chip that I could take advantage (and if so, how would I do that?)

Thanks![url=https://alchitry.com/collections/all/products/alchitry-au][/url]
