in the example hid-data of vusb:



why is it [22] ?

Why don't we use it in hid-data example?
I only see report descriptor there.

Okay, so I'm a newbie. So please bear with me on this This is the report descriptor that can be found on the firmware of the hid-data example. PROGMEM char usbHidReportDescriptor[22] = { /* USB report descriptor */ 0x06, 0x00, 0xff, // USAGE_PAGE (Generic Desktop) 0x09, 0x01, // USAGE (Vendor Usage ...

What kind of transfer is used in the hid-data example? Is it control transfer or interrupt transfer? Because I know only these two can be used by low-speed device. I think it's control transfer. But I'm not really sure. I know that control transfer has setup, data and status stages. But I don't know...

These two function are used in the commandline tool of the hid-data example.

Does this two functions are the same with the GetReport & SetReport functions of the HID?
I know this sounds silly and at first glance the should be the same. But I just want to make sure.

I managed to communicate with the device as well as sending and receiving bytes

The trick is to get rid of include "osccal.h" before you compile the hidtool.
And then add it again after you finish compiling

If anyone wanna know more, look at the hid-data on attiny 45 post

See usbconfig.h carefully. You have to define USB_CFG_HAVE_MEASURE_FRAME_LENGTH to 1 and include "osccal.h" here. hi Osamu, I managed to connect the device to the host. I put #include "osccal.h" in the usbconfig.h just like you showed. the device is now recognized by the host. b...

hi Maxi, I managed to connect the device to the host. I put #include "osccal.h" in the usbconfig.h just like you showed. the device is now recognized by the host. but now I have trouble trying to communicate with the device. I buuilt the host software according to the readme file BUILDING ...

the above is written by me, lol!

hi, thanks for the answers. I tried to put the OSCCAL into the main.c of HID_DATA and then to call it in the main program (int_main(void)) It doesn't work so far. But I maight have call it the wrong way. The program below is how I put the OSCCAL into the main.c and how I call it in main. Any ideas a...

what did you change when you adapted easylogger to hid-data example? So just get a fresh copy of the hid-data example, edit the makefile (DEVICE, FUSE_L & FUSE_H), edit usbconfig.h (port/pin configs) Add OSCCAL from libs-device and that should be about all there is to it. Hey Maxi, I tried to a...

I'm trying to implement hid-data example to ATtiny45. My template project is easylogger since it uses the same controller, simple and I already made it. It works fine. I modified the circuit a little bit. Some datas: frequency is 16500000 Hz fuse high is 0xdd fuse low is 0xe1 Note : these are the va...

Just to confirm I have successfully had both of those examples running on my ATtiny45 so it certainly can be done. I have no idea what could be causing your particular problem but i'd guess that its something minor that you have simply overlooked. Perhaps when you post your sources someone will spo...

Hi there, Newbie here I've tried to get the hid-data example on a tiny45. I used some parts of the Easylogger project to adopt it to the tiny. EasyLogger works perfectly. Now, the device is recognized. But after some seconds, it says there's a problem and that the device won't work correctly.. I can...
