Problem with STM32 HID #166

Closed modjo756 closed 10 years ago

modjo756 commented 10 years ago

Hi, i'm a newbie on stm32 and usb but i want to communicate with my stm32f3 discovery and my pc (with Qt). For this card (f3 discovery) i have an exemple with usb hid. Windows detect my card and i can moove the cursor with it. I downloaded hidapi and test "testgui.exe" it works for my keyboard and mouse but don't detect my stm32 ! I don't know why because windows recognise it and install hid driver. Do you have a solution to resolve it ? I also tested hidtest.cpp with Qt and it's the same problem (detect my mouse ... but not the stm32)

signal11 commented 10 years ago

Qt has nothing to do with HIDAPI.

Keyboards and mice aren't directly able to be manipulated with HIDAPI on windows. Try a joystick if you want to see something work.

HIDAPI is designed for communicating with HID devices which are vendor-defined (0xff) and have vendor-defined data in their reports.

Thank's for your answer. i just use qt with the dll to test if it's works (i know that qt has noting to do with HIDAPI. HIDAPi detect a 3dconnexion mouse (space pilot) and give data. My stm 32 have a vid and pid. See under the descriptor file of it

include "usb_lib.h"

include "usb_desc.h"

For information libusb give me the pid and vid for it.

if i launch zadig.exe, it say that about stm32 driver : HidUsb (v6.1.7601.18199)

Why hidapi can't detect his ?

signal11 commented 10 years ago

hid is an interface level class. it takes more than having a vid and pid. plug it into a Linux box and check the log and lsusb for errors. hidapi will give you all the devices that windows will show it.

Hi, when i connect my card to ubuntu it works (the mouse cursor mouve) and when i write the commande lsusb -v that's the result under :

signal11 commented 10 years ago

"check lsusb" doesn't mean send me the output without looking at it. Did you notice where the interface descriptor claims to be a mouse, and using the boot protocol? Please have a look at the hid specification for information on what to set those values to.

Let me know if you find anything ? :-)

signal11 commented 10 years ago

Yeah, I'll get right on that. I love combing through hundreds of lines unformatted code containing other people's problems.....

On top of that, I already told you what I found before. Your interface descriptor says MOUSE and BOOT. Please have a look at the HID specification for information on what to set those values to.

If you're really looking for someone to dig through your specific problems and do this project for your, I'd be happy to do it for a fee (consulting services) at an agreed upon rate, so long as this isn't a school project.

modjo756 commented 10 years ago

I apologize but i don't know how to comment the code on git hub ! It's not a project for work or school i just want to communicate with my card by usb (and understand how it works). Today i'm looking to find where is the specification of HID on stm. After that i will don't disturb you more longuer.

Click the text which says "Github Flavored Markdown" at the top of the box you're typing in.

i just want to communicate with my card by usb (and understand how it works).

Then you need to start by learning how USB works. See Jan Axelson's resources and book at www.lvr.com . Also see the specification documents (including HID) at USB.org.

After that i will don't disturb you more longuer.

It's ok if you ask questions, but learn how to ask the right questions the right way: http://www.catb.org/esr/faqs/smart-questions.html

Since it's been a long time, I'm going to close this. If you have any additional questions on this topic. Please feel free to reopen.
