cp2130's Issues

PyUSB

Great library!

For me to get it to work I had to change the order of imports in __init (https://github.com/drbild/cp2130/blob/master/cp2130/__init__.py#32) as the usb import did not raise an exception, but it then failed with LIBUSB_ERROR_NOT_SUPPORTED [-12] error. However import pyusb first worked well

I also had to remove the call to is_kernel_driver_active in https://github.com/drbild/cp2130/blob/master/cp2130/usb/pyusb.py as it was marked as NotImplemented.

I have pyusb 1.2.1 installed. (import usb, usn._version.version)

Help

Hi, I am using cp2130 now. A questions, the document say to configure the pin's mode (gpio, usb, spi) need a site-software named "XPRESS CONFIGURATOR", I did not know that means I must use "XPRESS CONFIGURATOR"? Can I configure it by codeing with the api? (with out XPRESS CONFIGURATOR)

Typo / Bug in spi.py

Thanks for writing and sharing such a useful python package. I just found a bug in the spi.py file.

There is an typo in the method "write" in the SPIChannel class. Lines 92 and 93 are

    op = lambda: self.chip.write(data)
    return self._do(op, data)

And, line 93 should be

    return self._do(op, cs_hold)

Cheers,
SaeWoo

OSError: [WinError 126] The specified module could not be found

The code run fail right at the 3rd line "chip = cp2130.find()"
Below is all the log. I tried to disable "libusb1" to force it use "pyusb" but also failed to detect device.

I check the connection with hardware is OK. I also could see the SPI device in the device manager. I used the verified Application for my HW to check the SPI communication with HW, and everything is OK.

BTW, I'm using Windows 8 and python 3.6.2.

array.array.to_string is deprecated in python 3 and removed in 3.9

The straightforward fix would simply be to use to_bytes instead, although this would break backwards compatibility with python 2. However, since python 2 hasn't been supported in four years, I don't think that should be a problem.

Seems this was noticed a while back and a PR was opened here. #5.
I'm quite happy to make this change myself.
