fx2lafw is an open-source firmware for Cypress FX2 chips which makes them usable as simple logic analyzer 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, 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:

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 devices 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 Various adapters are available, for example RS422/RS232/CAN, galvanic isolation, "BNC divider".

Download

$ git clone git://sigrok.git.sourceforge.net/gitroot/sigrok/fx2lafw

Usage

Build sigrok

  • Build and install a sigrok frontend (CLI or GUI) with libsigrok >= 0.1.1 (or latest git HEAD) for your platform as usual, see e.g. Linux, Mac OS X, FreeBSD, or Windows.

Install the udev rules file

These steps prevent the need to run sigrok as superuser.

  • Copy the udev rules file from sigrok/libsigrok/contrib/z60_libsigrok.rules to /etc/udev/rules.d/.
  • Restart udev: sudo /etc/init.d/udev restart.

Build fx2lafw

$ cd fx2lafw
$ git clone git://github.com/mulicheng/fx2lib.git
$ make
$ sudo cp hw/*/build/*.fw /usr/local/share/sigrok-firmware/

Where /usr/local is your installation prefix.

Test

$ sigrok-cli -D

If everything has worked, sigrok can now see your fx2lafw device, ready for use.
