QUESTION
Writing some C code for USB mouse.
More specifically writing configuration and information to mouse like poll, sensitivity, button actions, colors (light), tactile alters, OLED etc.
Started out with this old article where libhid
is recommended over libusb
.
Looking at libhid it seems to since have died. Last commit on that project is from 2012, - and it is C++. But I found some links saying one should go over to hidapi
.
However, hidapi also seems to be fairly dead. Last commit from 2016. Or perhaps it is simply stable?
It could look like one is better off using libusb
after all. Starting out with a 15 year old article - it is not that much of a stretch.
Question is if I am missing something? Is libusb
the way to go?
Have done some quick tests with libusb-1.0.0-dev
ANSWER
Answered 2020-Apr-09 at 18:19libusb recommend using hidapi for USB HID devices. hidapi can use a different backend depending on the OS, e.g. hid.dll in Windows, either hidraw or libusb in Linux, so it's using native USB drivers.
Be aware though that hidapi doesn't give you the same level of control over the packets you send. It's higher level than libusb and some of the parameters that it uses for requests are fixed (e.g. bRequest value).
hidapi is also not currently maintained, if that is a concern to you.
Update: As of June 4th 2019, hidapi was moved to libusb/hidapi and is now being actively maintained again.
Personally I'd say use hidapi if it works fine for your project, but if the device's protocol doesn't follow the HID standard then you'll run into trouble and will probably need the control that libusb gives you.
QUESTION
I'm working on a simple app where I want to list out a user's GitHub repos in a RecyclerView. I'm using this as my endpoint while building this.
The ProblemThe problem I'm facing is that the GitHub API returns only 30 repos in one go. To get more, I can append a per_page=100
(100 is the maximum) to my query string; But, what do we do about users with more than 100 repos?
The solution the API docs provide is to get the next;
url from the "Link" response header to make a second API call.
How does one go about this? Thanks!
