PyHid

A python wrapper for the hidapi library

How to use this library

This project is designed to simply slot into your codebase without the need to install anything

You will need to grab the latest binary from hidapi and place it inside the pyhid/lib folder This has only been tested on windows, so if you want to run it on linux you will need to modify pyhid/hidapi.py and set pathToDll to point to the location of the linux shared library binary. Please feel free to submit a pull request that adds proper cross-platform support :)

Getting started with the API

hidapi.py exposes the raw C API of hidapi, so if you want you can use that directly in more or less the same way you would use hidapi in C.

For a more "pythonic" approach, use pyhid.py which exposes the Hid, DeviceInformation, Device and Buffer classes

Example

from pyhid import pyhid

with pyhid.Hid() as hid, hid.enumerate() as enumeration:
    for deviceInfo in enumeration:
        if(deviceInfo.product_string):
            print(deviceInfo.product_string)
            print("vendor id: " + hex(deviceInfo.vendor_id))
            print("product id: " + hex(deviceInfo.product_id))
            print("Usage/page:" + hex(deviceInfo.usage) + " / " +  hex(deviceInfo.usage_page))
            print("")
            
        if(deviceInfo.vendor_id == 0x16c0 and deviceInfo.usage_page==0xffab):
            path = deviceInfo.path
            with deviceInfo.connect() as device:
                a = pyhid.Buffer(3)
                a[1] = ord("b")
                device.write(a)
