All devices use a 24MHz crystal.
All devices use a 24MHz crystal. For 8 probes the FX2 pins PB0-PB7 are used, for 16 probes PB0-PB7 and PD0-PD7. For analog support PD0-PD7 (plus additional hardware) is usually used.


<sup>1</sup> Sampling with 8 channels works fine, 16 channel sampling is not yet supported.<br />

<sup>2</sup> Analog signal support is not yet implemented.<br />
<sup>1</sup> Analog signal support is not yet implemented.<br />
<sup>2</sup> Even though this device has the same USB VID/PID as the CWAV USBee AX-Pro, it only has 8 channels and no analog support.<br />
<sup>3</sup> Clone of the USBee AX and Saleae Logic. "Mollex" is the name of the guy who seems to sell it on some forum.<br />
<sup>4</sup> Clone of the USBee AX (SX?) and Saleae Logic, see also [http://iteadstudio.com/copied/hack-a-saleae-logic-analyzer/ here] and [http://iteadstudio.com/produce/seleae-logic-usbee-ax-usb-blaster/ here]. Dissection by a user [http://www.todopic.com.ar/foros/index.php?topic=32657.0 here]. Seems to be the same hardware as the [[Robomotic MiniLogic]].<br />
<sup>5</sup> It seems 6-Labs [http://electronicsjunk.com/index.php?option=com_content&view=article&id=52:saleae-logic-analyzer-&catid=34:electronics&Itemid=59 has/had permission from Saleae] to distribute the hardware in Ukraine (only)? [http://translate.google.com/translate?sl=ru&tl=en&u=http%3A%2F%2F6-lab.com%2Fen%2Flogic-u-adapters.html Various adapters] are available, for example RS422/RS232/CAN, galvanic isolation, "BNC divider".<br />
<sup>6</sup> There is apparently [http://we.easyelectronics.ru/Turtleblast/poluchil-xzl-studio-ax.html#comment53143 a post from the author of XZL-Studio AX] in some forum.<br />
<sup>7</sup> There's [http://lab.robomotic.com/shop?page=shop.product_details&flypage=flypage.tpl&product_id=27&category_id=6 an RS232/RS485/RS422/CAN converter board] for this.<br />

Latest revision as of 01:13, 14 February 2024

fx2lafw is an open-source firmware for Cypress FX2 chips which makes them usable as simple logic analyzer and/or oscilloscope hardware.

It is licensed under the terms of the GNU GPL (version 2, or later) and written in C, using sdcc as compiler, and fx2lib as helper library.

Hardware overview

The fx2lafw firmware is meant to work on any FX2-based hardware, including logic analyzers, FX2 eval boards, oscilloscopes, or other hardware which has this chip on-board.

Here's a quick overview of some of the relevant hardware information we have about the various devices.

The devices marked as Clone are those that clone the USB VID/PID of the original product, and also have no own PC software/firmware, but instead illegally ship the software of the original product/manufacturer.

Logic Analyzers / mixed-signal devices

The following logic analyzer / mixed-signal devices are supported (if marked as such) by fx2lafw (and by the fx2lafw driver in libsigrok):

All devices use a 24MHz crystal. For 8 probes the FX2 pins PB0-PB7 are used, for 16 probes PB0-PB7 and PD0-PD7. For analog support PD0-PD7 (plus additional hardware) is usually used.

1 Analog signal support is not yet implemented.
2 Even though this device has the same USB VID/PID as the CWAV USBee AX-Pro, it only has 8 channels and no analog support.
3 Clone of the USBee AX and Saleae Logic. "Mollex" is the name of the guy who seems to sell it on some forum.
4 Clone of the USBee AX (SX?) and Saleae Logic, see also here and here. Dissection by a user here. Seems to be the same hardware as the Robomotic MiniLogic.
5 It seems 6-Labs has/had permission from Saleae to distribute the hardware in Ukraine (only)? Various adapters are available, for example RS422/RS232/CAN, galvanic isolation, "BNC divider".
6 There is apparently a post from the author of XZL-Studio AX in some forum.
7 There's an RS232/RS485/RS422/CAN converter board for this.
8 Digital channels have invalid numbers, check XZL Studio DX for details.

Download

Released versions of the source code can be downloaded here: 

 http://sigrok.org/download/source/sigrok-firmware-fx2lafw/

There are also pre-built firmware files that can be used without having to build them from source: 

 http://sigrok.org/download/binary/sigrok-firmware-fx2lafw/

Or you can get the latest development snapshot of the source code from git: 

$ git clone git://sigrok.org/sigrok-firmware-fx2lafw

You can also browse the source code via gitweb.

Usage

Build sigrok

  • Build and install a libsigrok frontend (CLI or GUI) with libsigrok >= 0.1.1 (or latest git HEAD) for your platform as usual, see Building.

Install the udev rules file

These steps prevent the need to run libsigrok frontends as superuser.

  • Copy the udev rules file from libsigrok/contrib/60-libsigrok.rules to /etc/udev/rules.d/
  • Install either 61-libsigrok-uaccess.rules or 61-libsigrok-plugdev.rules to the same directory.

The 61-libsigrok-uaccess.rules is typically used on a system using the systemd/logind mechanism to grant access to plugged in devices to the currently active user. 61-libsigrok-plugdev.rules grants access to all users in the plugdev group. The latter may also serve as a template for creating a local, system specific access rule.

Build fx2lafw

$ cd sigrok-firmware-fx2lafw
$ ./autogen.sh
$ ./configure
$ make
$ sudo make install

This will install the firmware files into /usr/local/share/sigrok-firmware/, per default.

Pre-built firmware files

There are also pre-built firmware files that can be used without having to build them from source (see above).

Cypress FX2 vs. FX2LP

Various devices supported by fx2lafw can use either the older Cypress CY7C68013 (FX2) or the more recent Cypress CY7C68013A (FX2LP).

There are various differences between the two ICs, see AN4078 - Migrating From EZ-USB FX2 to EZ-USB FX2LP (PDF) for the details.

There are known cases of e.g. the CWAV USBee SX having shipped with an FX2 at some point, and more recent units shipping with an FX2LP. Also, it's not too uncommon that some FX2 "eval board" or clone of an existing logic analyser (e.g. CWAV USBee SX or Saleae Logic ones) has "CY7C68013A (FX2LP)" chip markings, but in reality it really is an older "CY7C68013 (FX2)".

The fx2lafw firmware supports both devices (FX2 and FX2LP).
