Classes for interfacing with XESS FPGA boards via USB.

Project description

.. image::

XSTOOLs is a collection of Python classes for interfacing to
XESS FPGA boards through a USB connection.

Look in the ``bin`` to see several examples of command-line
utilities that use these classes to perform operations on
XESS boards.

* Free software: GPL V3 license
* Documentation:


* Python package for accessing XuLA FPGA boards through a USB link.
* Command-line tools for configuring the FPGA, uploading/downloading the
serial flash and SDRAM, and running diagnostics on the board.
* GUI tool that performs the same functions as the command-line tools.

v0.1.25 (2015-06-05)

* Fixed problem where flash and SDRAM couldn't be accessed in gxstools
because I appended 'bitstream' to the attribute names.

v0.1.24 (2015-03-16)

* Modified to prevent accidental triggering of serial BREAK.

v0.1.23 (2015-02-03)

* Modified and to support new serial BREAK command.
* Added .cmd file to initiate each XSTOOLs script in a Windows command window.

v0.1.22 (2015-01-26)

* Modified to support non-ZPUino use of the USB-to-serial server.

v0.1.21 (2015-01-07)

* Modified so pyusb < 1.0.0b1 is installed as a dependency since the
newer 1.0.0bX libraries cause a problem with finding XESS boards on USB ports.

V0.1.20 (2014-12-17)

* Modified to include microcontroller firmware hex files for the XESS

V0.1.19 (2014-12-12)

* Modified so pyusb <= 1.0.0b1 is installed as a dependency since the
newer 1.0.0b2 library causes a problem with finding XESS boards on USB ports.

v0.1.18 (2014-12-10)

* Fixed query for XESS USB devices which failed for some USB libraries.

v0.1.17 (2014-11-06)

* Fixed handling of XuLA/XuLA2 boards with old firmware or with the USB-to-JTAG
path disabled.

v0.1.16 (2014-10-27)

* Added command-line and GUI methods for setting/getting flags in XuLA/XuLA2 boards.
* Enabled loading of .bit files into serial configuration flash via gxstools.
* Updated hex file to newest version of the PIC 18F14K50 firmware.
* Added USB-to-serial bridge server between XuLA board and virtual comm port on PC.

v0.1.15 (2014-05-16)

* Added support for upload/download of signed integers to memio methods.

v0.1.14 (2014-05-05)

* Fixed FPGA bitstreams to remove errors during SDRAM upload/download.

v0.1.13 (2014-04-09)

* Add bidirectional communication channel between host and FPGA:

v0.1.12 (2014-02-03)

* Added graphical front-end to XSTOOLs:

v0.1.11 (2014-01-03)

* Fixed bit direction for checking status bits in

v0.1.10 (2013-11-20)

* Added support for XuLA2-LX9 board.

v0.1.9 (2013-05-15)

* Added ability to load Xilinx bitstream files directly into serial configuration flash.
* Fixed byte order of addresses sent to the W25X serial flash.

v0.1.8 (2013-05-14)

* Fixed FlashDev class so address bounds could not go outside the min/max addresses for the device.

v0.1.7 (2013-05-11)

* Added FlashDevice class for reading/writing flash memory devices.
* Made Pic18f14k50 class inherit from the FlashDevice class for flash read/write operations.
* Added routines for reading/writing serial configuration flash on the XuLA and XuLA2 boards.
* Extended to enable serial flash uploading and downloading.

v0.1.6 (2013-04-30)

* Fixed so it works under linux.
* Fixed USB read/write timeouts so they are dependent upon the amount of data transferred.
* Replaced exit() with sys.exit() in scripts.

v0.1.5 (2013-04-19)

* Added XuLA firmware .hex files for use with
* Fixed so it would upgrade XuLA board firmware by default.
* All user-accessible scripts now use to get a unified version #.
* Added .rules file for USB connections to XESS boards.

v0.1.4 (2013-04-01)

* Replaced bitarray module with pure-Python bitstring module.

v0.1.3 (2013-02-15)

* Fixed so multiple XsUsb objects can share a single USB link to access an XESS board.

v0.1.2 (2013-02-14)

* Changed CR-LF EOL in .py files to LF EOL so linux wouldn't barf.

v0.1.1 (2013-01-23)

* Use pypubsub instead of wxpython for publish/subscribe communications.

v0.1.0 (2013-01-06)

* Initial release.
