The sigrok project aims at creating a portable, cross-platform,
Free/Libre/Open-Source signal analysis software suite that supports various
device types (such as logic analyzers, oscilloscopes, multimeters, and more).

sigrok-firmware-fx2lafw is a Free/Libre/Open-source firmware for logic
analyzers based on the Cypress EZ-USB FX2(LP) chip.


sigrok-firmware-fx2lafw is in a usable state and has had official
tarball releases.


 - git
 - make
 - autoconf >= 2.63
 - automake >= 1.11
 - sdcc (>= 2.9.0)


 - In order to build fx2lafw you need the 'sdcc' compiler (>= 2.9.0).
   On Debian you can install it via:

     $ apt-get install sdcc

   This project has been tested to work with sdcc 2.9 and 3.x.

 - You need libsigrok >= 0.1.1 in order to make use of fx2lafw. Earlier
   versions didn't have support for FX2 devices using this firmware.

Pre-built firmware files

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


The fx2lafw code uses a (slightly modified) "fx2lib" helper library.
