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: https://xstools.readthedocs.org.

Features
--------

* 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.

History
-------

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 usb2serial.py to prevent accidental triggering of serial BREAK.

v0.1.23 (2015-02-03)
---------------------

* Modified usb2serial.py and xscomm.py 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 usb2serial.py to support non-ZPUino use of the USB-to-serial server.

v0.1.21 (2015-01-07)
---------------------

* Modified setup.py 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 setup.py to include microcontroller firmware hex files for the XESS
boards.

V0.1.19 (2014-12-12)
---------------------

* Modified setup.py 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: xscomm.py.

v0.1.12 (2014-02-03)
---------------------

* Added graphical front-end to XSTOOLs: gxstools.py.

v0.1.11 (2014-01-03)
---------------------

* Fixed bit direction for checking status bits in xsi2c.py.

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 xsload.py to enable serial flash uploading and downloading.

v0.1.6 (2013-04-30)
--------------------

* Fixed xsusbprg.py 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 xsusbprg.py.
* Fixed xsusbprg.py so it would upgrade XuLA board firmware by default.
* All user-accessible scripts now use xstools_defs.py 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.
