  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:
[  941.440081] usb 2-2: new high-speed USB device number 3 using xhci_hcd

[  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!


  Alchitry AU
Posted by: beginer_fpga - 04-16-2019, 08:07 AM - Forum: General Questions - Replies (1)

Hi all,
I just started in fpga and I got the Alchitry board AU
I would like to now with speed in I have to choose when I create a project with Vivado using Verilog?
Thanks


  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]


  what is the resolution of the ADC in Alchitry Cu ?
Posted by: sumane123 - 04-08-2019, 05:22 PM - Forum: General Questions - Replies (3)

how many bits are used to represent an analog value ?


  FTDI chip heating
Posted by: lucas.rivas - 04-08-2019, 05:20 AM - Forum: General Questions - Replies (1)

Is it normal that when i connect the Alchitry Au to the pc without programming anything to it, (just running the original preinstalled program), the FTDI chip get hot?


  Simple XADC Example
Posted by: prebys - 04-06-2019, 02:33 AM - Forum: Tips and Tricks - No Replies

It was a little frustrating trying to figure out how to use the onboard ADC, so once I got it working, I thought I would share it. 

This is a simple project to scan the temperature, internal voltage levels, and dedicated analog input and display them in hex on the Alchitry Io board.  All channels are continuously scanned, and the channel to be displayed is selected with the first 4 DIP switches. 


Details are in the header of the top file.

"Alchitry Labs cannot be installed on systems with JRE version lower than 8."
I dont really know what is that. I hope you can help me with this.
