Make K40Whisperer work with the default windows driver

Tatarize · December 13, 2020, 3:07pm

I made a version of K40Whisperer that uses the default driver. The code isn’t too hard to interface with and but could certainly make a difference. Obviously mac and linux users would still get LibUSB but it would make a great option or default attempted fallback method.

I tried to tweak the fewest things possible. It basically just takes this 60 line class here:

github.com

tatarize/K40-Whisperer/blob/scorchworks/nano_library_dll.py

from nano_library import K40_CLASS as K40_LIBUSB
from ctypes import *

# Code donated to public domain.


class K40_CLASS(K40_LIBUSB):
    def initialize_device(self, USB_Location=-1, verbose=False):
        try:
            self.dev = WindllDevice(USB_Location)
        except:
            raise Exception("Could not load CH341 Windll")
        self.USB_Location = self.dev.driver_index
        return self.USB_Location

    def release_usb(self):  # Override to avoid usb.util command.
        self.dev.close()
        self.dev = None
        self.USB_Location = None
