I cannot get this to work in Linux.

pid and vid are defined before

dev = MCP2210(my_vid, my_pid)

I just get "IOError: open failed". It sounds like it cannot open the device.

Do I need to install something else?

The library does not work with python 3, probably because the buffer() function has been replaced with memoryview().

Hi, I was just looking at using this, but notice that you are using a python 'hid' module.

Which hid module is this ??

I used this repo from osx and managed to get a hello world working. But on the windows side it's less painful to use the dll provided from microchip. You can find it buried in here: http://ww1.microchip.com/downloads/en/DeviceDoc/MCP2210_DLLv2.zip

Is it possible to know which libraries/packages are necessary to run the mcp2210 package with Linux/Windows?

I ran in problems with win7/64bit regarding the hid library (installed afterwards with 'pip install hidapi') and then with
from mcp2210 import commands
ImportError: cannot import name commands

Some specific errors, like 'bus in use' and 'chip locked' should be represented by specific subclasses.

Currently we wait for a short period after each command. Instead, we should recognise the 'transfer in progress' error and try again.

hi,@Arachnid
when i driver MCP2210 in Python3.5.2 window7,i encounter a problem:

>>> from mcp2210 import MCP2210
>>> dev = MCP2210(0x04D8,0x00DE)
>>> dev.manufacturer_name = "123"
Traceback (most recent call last):
  File "<pyshell#2>", line 1, in <module>
    dev.manufacturer_name = "123"
  File "D:\Python35-32\lib\site-packages\mcp2210-0.1.4-py3.5.egg\mcp2210\device.py", line 77, in setter

TypeError: ord() expected string of length 1, but int found

PS： i have modifyed the code according to @bddap in the "Pull Requests"
please give me a hand.

Hi;
My apologies, through a lot of trial and error I have managed to solve my initial problems with I/O control.

If I have multiple devices on the network, and have the gpio.pin set as a cs pin, how do I select the pin prior to a data transfer to that the correct device is selected ?

Do I have to do this by defining the pin as an i/o pin and then pull it high/low before and after a data transfer or is there a method that uses the cs pin instead ?

Also, is it possible to do data transfer using hex values i.e: dev.transfer(0x8d,0x14,0xaf)

Got the following issue when working with Python 3.7 on Windows 10.
