MyHIDAPI

https://github.com/tenderlove/myhidapi

DESCRIPTION:

This is a small wrapper around HIDAPI. I couldn't get other HIDAPI wrappers to work, so I wrote this one. I'm using it to communicate with my keyboard, so it really only supports enough of the HIDAPI to do that.

FEATURES/PROBLEMS:

Incomplete
No tests
Seems to work (for me)

SYNOPSIS:

 devices = MyHIDAPI.enumerate 0x0, 0x0
 dev = devices.find { |dev| dev.product_string == "ErgoDox EZ" }

 handle = dev.open

 while !handle
   p "retry"
   handle = dev.open
 end

 p handle

 buf = [0x0, 0x3, 35]
 loop do
   break if handle.write buf.pack('C*')
 end
 puts "done writing"

 buf = handle.read_timeout 1, 500
 p buf

REQUIREMENTS:

This depends on libhidapi.

INSTALL:

Install hidapi. On MacOS that is brew install hidapi
