  30. - New 'reset' command resets the Greaseweazle to power-on settings
  31. - Motors off, drives deselected, power-on pin levels and delay values
  32. ** v0.11 - 21 January 2020

  34. - The device argument is now optional!
  35. - USB: Provide a serial-id string to the host
  36. - Identifier is unique to each Greaseweazle device
  37. - Allows disambiguation between multiple Greaseweazle devices
  38. - Recommended: Full flash from HEX file (embeds serial in bootloader)
  39. - Ubuntu: Udev script now creates a /dev/greaseweazle symlink
  40. ** v0.10 - 17 January 2020
  41. - STM32F7xx: Multi-drive support via drive-select config option
  42. - Up to three Shugart drives or two IBM/PC drives
  43. - gw.py read|write --drive {a,b,0,1,2}
  44. - See the "Drive Select" wiki page
  45. ** v0.9 - 7 January 2020
  46. - Activity LED
  47. - Lights while a USB-issued command is in progress
  48. - Flashes when enumerated but idle in the firmware-update bootloader
  49. ** v0.8 - 6 January 2020
  50. - STM32F73xx: Various Fixes and Improvements
  51. - Allow Firmware Update mode to be forced via strapping Serial RX/TX
  52. - Fix bogus sample values at start of read flux values
  53. - Fix some time constants to be in units of the sample clock
  54. - USB: Advertise USB 2.0 device descriptor
  55. ** v0.7 - 6 December 2019
  56. - USB: Fix end-of-stream detection on track writes
  57. - Writes of empty/unformatted tracks sometimes hung forever
  58. - No Flux Area: Firmware automatically masters long NFAs during track writes
  59. - Generating no flux transitions does not read back as a NFA
  60. - STM32F73xx: Initial support for new STM32 MCU
  61. - Two HEX files are included: Use Greaseweazle-F1-* for existing boards!
  62. - Single unified UPD file containing both firmware images
  63. ** v0.6 - 15 November 2019
  64. - gw.py: Big overhaul of underlying Python package
  65. - Action (read, write, update) must come first on the command line
  66. - eg. "python3 gw.py read --ecyl=39 foo.scp COM3"
  67. - gw.py: New action "delays" to print/set delay parameters
  68. - eg. "python3 gw.py delays --step=10000" to increase step time to 10ms
  69. ** v0.5 - 11 November 2019
  70. - USB: Overhaul the protocol and allow writes to be terminated at index
  71. - Terminate-at-index is always used by current Python control script
  72. - Terminate-at-index prevents an over-long write from overwriting itself
  73. - Fix interruption of track writes (eg. KeyboardInterrupt)
  74. - gw.py: New option --adjust-speed to normalise flux times for target drive
  75. - Measures RPM of the target drive and calculates an adjustment factor
  76. ** v0.4 - 5 November 2019
  77. - Blinky: Diagnostic test firmware to detect fake STM32 chips
  78. - https://github.com/keirf/Greaseweazle/wiki/STM32-Fakes
  79. - Floppy Write: Fix for very short flux timings

  81. - USB: Small improvement to double-buffer logic
  82. ** v0.3 - 30 October 2019
  83. - Bootloader: Fix Programming-Jumper detection
  84. - Read Track: Various minor fixes
  85. - SCP: Fix the SCP file headers generated by "gw.py read"
  86. ** IMPORTANT USER INSTRUCTIONS **:
  87. - Users must serial-update using the v0.3 HEX file
  88. - DO NOT update from v0.2 using the UPD file
  89. - May need to install the crcmod package: eg "pip3 install crcmod"
  90. ** v0.2 - 29 October 2019
  91. - USB: Fix hangs during "gw.py read"
  92. - Thanks to Charlie Smurthwaite for telling me how to fix this!
  93. - USB: Improved bandwidth (double-buffered IN/OUT endpoints)
  94. - Reduces risk of buffer underflow/overflow during disk operations
  95. - Firmware Update: Requires a jumper across A14 (aka DCL) and GND
  96. - eg. "python gw.py update Greaseweazle-v0.2.upd COM3"
  97. ** v0.1 - 17 October 2019
  98. - First release
