# ver 1.0 - may 2020 - initial release
|
|
||||||
# ver 1.2 - june 2020 - added save to SPI EEPROM functionality
|
|
||||||
# - fixed the args parsing
|
|
||||||
# - added auto load wait option
|
|
||||||
# - added save SPI option
|
|
||||||
# ver 1.3 - july 2020 - removed some of the debug stuff
|
|
||||||
# - removed address scrolling when loading
|
|
||||||
# ver 1.6g - Aug 2020 - Lunches GUI when no parameters specified (code contributed by John Gerrard)... requires PySimpleGUI module "pip install PySimpleGUI"
|
|
||||||
# - small fixes to the output
|
|
||||||
# ver 1.6e - fixed bug with SPI==y
|
|
||||||
#
|
|
||||||
# ver 2.0rc1 - Oct 2020 - save parameters in GUI
|
|
||||||
# - .bin and .hex file support
|
|
||||||
# - binary mode upload with packets of 128-512 bytes at a time
|
|
||||||
# - Save to SPI works with any type of data range (any source file less than 128 bytes gets "padded" with 0xFF)
