  43. - USB: Provide a serial-id string to the host
  44. - Identifier is unique to each Greaseweazle device
  45. - Allows disambiguation between multiple Greaseweazle devices
  46. - Recommended: Full flash from HEX file (embeds serial in bootloader)
  47. - Ubuntu: Udev script now creates a /dev/greaseweazle symlink
  48. ** v0.10 - 17 January 2020
  49. - STM32F7xx: Multi-drive support via drive-select config option
  50. - Up to three Shugart drives or two IBM/PC drives
  51. - gw.py read|write --drive {a,b,0,1,2}

  54. - Activity LED
  55. - Lights while a USB-issued command is in progress
  56. - Flashes when enumerated but idle in the firmware-update bootloader
  57. ** v0.8 - 6 January 2020
  58. - STM32F73xx: Various Fixes and Improvements
  59. - Allow Firmware Update mode to be forced via strapping Serial RX/TX
  60. - Fix bogus sample values at start of read flux values
  61. - Fix some time constants to be in units of the sample clock
  62. - USB: Advertise USB 2.0 device descriptor
  63. ** v0.7 - 6 December 2019
  64. - USB: Fix end-of-stream detection on track writes
  65. - Writes of empty/unformatted tracks sometimes hung forever
  66. - No Flux Area: Firmware automatically masters long NFAs during track writes
  67. - Generating no flux transitions does not read back as a NFA
  68. - STM32F73xx: Initial support for new STM32 MCU
  69. - Two HEX files are included: Use Greaseweazle-F1-* for existing boards!
  70. - Single unified UPD file containing both firmware images
  71. ** v0.6 - 15 November 2019
  72. - gw.py: Big overhaul of underlying Python package
  73. - Action (read, write, update) must come first on the command line
  74. - eg. "python3 gw.py read --ecyl=39 foo.scp COM3"
  75. - gw.py: New action "delays" to print/set delay parameters
  76. - eg. "python3 gw.py delays --step=10000" to increase step time to 10ms

  78. - USB: Overhaul the protocol and allow writes to be terminated at index
  79. - Terminate-at-index is always used by current Python control script

  91. - Bootloader: Fix Programming-Jumper detection
  92. - Read Track: Various minor fixes
  93. - SCP: Fix the SCP file headers generated by "gw.py read"
  94. ** IMPORTANT USER INSTRUCTIONS **:

  100. - Thanks to Charlie Smurthwaite for telling me how to fix this!
  101. - USB: Improved bandwidth (double-buffered IN/OUT endpoints)
  102. - Reduces risk of buffer underflow/overflow during disk operations
  103. - Firmware Update: Requires a jumper across A14 (aka DCL) and GND
