Windows support for bootloader

xsrf commented 8 months ago

Adds windows support for the bootloader by fixing the USB and HID descriptors to proper values and adjusting end of scratchpad transfer detection.

Other than Linux, Windows will not allow any communication with a USB device that does not exactly follow the specs and matches USB descriptors. The original USB descriptor advertises a wMaxPacketSize of 64 which is invalid for low speed USB devices, causing enumeration to fail on many host controllers. The maximum allowed for low speed devices is 8 Bytes. The HID descriptor had a wrong Report Count and was missing a Report Size, resulting in an undefined or zero length of data it would accept.

Also added make_win.bat to build and flash the bootloader, as the make-file did not work properly for me on windows.

Fixes issues #21 and #24.

@cnlohr I tried the bootloader also on Debian Linux and minichlink uploads fine, but ends with errors when the chip is rebooted:

$ sudo ./minichlink -w neo_blue.bin flash -b

I guess that's fine though?

Unless the device has support for USB, that is exactly what it should do.

This is AMAZING. Thank you so much @xsrf
