Engine Cam/Crankshaft Simulator

tonebone — Sun, 31 Mar 2013 23:09:33 +0000

This is an example of how to simulate an engine crankshaft and camshaft hall effect sensor signal using the XMOS XK-1A Development Kit. It has been used to verify a DSpace engine control system. It is nice to be able to quickly generate errors and check how they are evaluated. There is a stub in the code that could also be used to simulate ignition and injector timing. Similar concepts could be used to perform evaluation of an actual camshaft and crankshaft signal.

Facebook client

Lele — Sun, 10 Mar 2013 15:11:22 +0000

Minimal XMPP (aka Jabber) client implementation tested with Facebook messaging host
(digest-md5 authentication, no tls connection required).

To use the project you need a Facebook account with at least a friend to talk with.
In module "main.xc" you must set the "XmppHostAddr" with the IP of "chat.facebook.com" (you can ping the URL to get the IP).

In module "XmppClient.c" you must set the account username and password:
static char UserName[41] = "YourFacebookUserName";
static char Password[41] = "YourAccountPassword";

SliceKit Coreboard in Easy-PC

asibbald — Wed, 06 Mar 2013 14:27:30 +0000

An Easy-PC Project and associated Library Files which is an exact reproduction of the XMOS Slicekit Core Board, but in Easy-PC format.

Note that this was done as an exercise to evaluate Easy-PC. Whilst I have checked the design extensively and I'm pretty sure it is correct, I have NOT had the board produced.

Open Source Implementation DSD over PCM

ghmfranken — Fri, 22 Feb 2013 10:31:56 +0000

This project is an effort to implement the DSD over PCM (DoP) open standard (both version 1.0 and 1.1) building on the XMOS software reference (3.3) . The DoP standard describes how a DSD stream can be encapsulated in PCM frames. A white paper describing the standard can be found here (http://dsd-guide.com/sites/default/files/white-papers/DoP_openStandard_1v1.pdf).

Slice Cobbler

Folknology — Tue, 12 Feb 2013 13:56:08 +0000

Slice boards are to small to adequately place breadboards because of their width restrictions (They have to be neighbourly), however you can cobble your pins from the Slicekit to your breadboard providing breakout using some headers, IDC cable and this. This board provides the breakout end of the cobbler that goes into the breadboard. you can use the onboard test headers (I recommend square) by populating them with an IDC male shrouded header. the IDC cable then links the two together.

Patchslice

Folknology — Thu, 07 Feb 2013 00:57:40 +0000

A small prototyping and patching slice board which can be used with the Xmos Slicekit system. This board is ideal for building small experimental projects to test with Slicekit. It is also useful for creating patch boards, adapters and connector boards from the slicekit standards to third party or older Xmos header style connectors.

sha-1 encription routine

colinbroad — Tue, 11 Dec 2012 00:05:06 +0000

Standard sha-1 encryption routine for xmos chip, The current version supports a sigle pass that will handle up to 64 bytes but I can finish it to allow any message size if there is interest.

The routine implements version 2, minimum memory usage. My current application uses a 64 byte salt before a 32 byte challenge and writing my own routine allowed me to pre encode the salt.

Remote control with 500Kbit/s fiber optic

Carpentier — Wed, 28 Nov 2012 03:11:04 +0000

I have realized a small project consisting of a remote control between 2 XK-1A boards. When pressing the buttons on the transmitting card, the leds light accordingly on the receiving card. The link between the 2 cards is one fiber optic (for only remote control) or 2 fiber optics if need duplex communication. The same program runs on the 2 cards and this program contains a transmitter thread and a receiver thread.

Mad Scientist Audio Interface

CivilDecline — Sat, 10 Nov 2012 05:19:45 +0000

So first, been working on this quite some time, the name is a little out there but was deemed "the mad scientist" by a friend quite a while ago and it stuck.

I've been working on this off and on since about oh May of this year(6/12) its come a long way. Thought I'd finally share.

Goal is to get the functionality of a comparable industry standard professional usb audio interface. Without sacrificing oh most of my pay check.

BotSlice

Folknology — Fri, 26 Oct 2012 16:05:09 +0000

BotSlice is a basic motor driving board for simple robotics and UAV type applications. BotSlice is a basic robot module designed for the Xmos SliceKit system using a PCIe edge card connector. This module can be used to drive up to 3 unipolar stepper motors or 12 unidirectional DC motors. It is also designed to be able to drive up to 14 pulse width controlled servos. Motor types can be mixed and matched between the different types in order to meet many different project requirements.

I2C LCD Driver

mnrsmith — Mon, 22 Oct 2012 20:53:20 +0000

This is a small library to drive an LCD matrix via the I2C bus that I ported from the Arduino code..

It will drive a 20x4 matrix like this: http://www.ebay.co.uk/itm/190637600054 commonly used by Arduino and should also work with 16x2 etc.

This LCD module includes a PCS8574n I2C interface with a HD44780 matrix driver.

It needs just the two pins for the I2C and can work with the i2c_master or i2c_simple xmos modules.

It is tested and working on the above display.

L2 card with Ethernet or USB part 2

Carpentier — Sat, 20 Oct 2012 23:10:26 +0000

Finally succeded with my XS1-L02A-QF124-C5 processor card and Ethernet.
The card worked perfect immediately.
This card has a dual core processor but is very small (35 x 60mm).
As with the previous card, all IO are 5V on the 25 pin PC compatible IO port and are from core1 . The ethernet and the yellow led on front is on core0.
The power supply iinput is a min B socket with only the VBUS power signal taken from it. It works from a PC port or from a USB charger.

The download include
-part list
-PCB Gerber files
-schematics
-photos

I can provide the PCB for 5USD.

An electronic schematic drawing program

Carpentier — Fri, 19 Oct 2012 13:22:56 +0000

For a long time, i needed a electronic schematic drawing program. Usually i make the PCB first then draw the schematic only after if required.
I think the schematic of an electronic realization is not as important as the PCB and or prototype. So the user should not need to take a long time for it. The software should allow to draw the schematic quickly and without effort, because what is more important is the PCB.

Here is the result, a free schematic editing program with a user manual and a sample schematic included with it.

USB to fiber optic

Carpentier — Sun, 30 Sep 2012 23:52:25 +0000

The project consist to control a High voltage CNC machine from a PC.
The machine is for example a Laser engraver , or a plasma arc cutter (the Plasma arc is the most subject to disturb other electronic equipment).
The USB connection is the most easy to use to connect a PC to another peripheral, but is very sensitive to High voltage noise ( produced when the laser or arc is switche on / off).
The project consist of two cards :
- A motor controller with fiber optic control input . which should be robust against electric noise

Simple generic control board with XS1-L2 or G4 chip

Carpentier — Wed, 26 Sep 2012 13:47:23 +0000

A simple control board that contains a powerful processor XS1-L2 or G4 chip.

The card should have a convenient communication interface (USB and/or ethernet) .

The card has for application digital motor control, so should offer a convient DB25 connector with input/output preferably 5V tolerant and 5V drive.

The card should be conveniently powered by the USB port. or in case of the ethernet interface by a mini usb or jack connector for powering.

Complete EagleCAD library for XMOS chips.

narutoxela — Tue, 28 Aug 2012 02:06:32 +0000

Some people on the forums including my self have a hard time finding EagleCAD libraries for the XMOS chips. So, I'm making a library containing all the current XMOS chips. Also please tell me if there are any mistakes in the library.

Note: EagleCAD 6.0 was used to make this library and is unfortunately uncompatible with older versions of EagleCAD. Sorry for the inconvinience....

Chips included:

XS1-G04B-FB144
XS1-G04B-FB512

XS1-L02A-QF124

XS1-L01A-TQ48
XS1-L01A-LQ64

Audio Post Processing: Reverb Demo

anilkumar — Wed, 18 Jul 2012 13:29:50 +0000

The algorithm implements a stereo-in, stereo-out feedback delay network reverberator, which is based on a design by Michael Gerzon and Miller Puckette. It consists of delay lines of various lengths combined through the use of scalars and of feedback around part of the total system. Basic elements in this example are Scalars, Mixers and Delays.
