HID Mouse

[Arin_t]

Hello,

I am new to HID and I have a question on HID Mouse communication.

I was able to modify the MikroBasic builtin HID example and successfully use it for PIC2550. But my problem is that when I change my descriptor file to a mouse descriptor, I get an error on detecting the HID interface in Winxp.

I would appriciate so much if someone can share some knowledge on HID mouse communication with me.

I am using Mikrobasic and PIC2550. My OS is Winxp.

Thanks,
Arin

Uses, my liby in C ansi.

read the comments.
Then I made an example of mouse, joystick etc.

Hi Fabim,

Thank you very much for replying to my post. I have already checked the link you sent me. Currently, I am able to send and receive data to pc using hid. My main issue is that I am not sure why my mouse program does not connect correctly. Here is my code. I hope this helps you more. Thanks very much for all your help.

Hi,
I think that

Code: Select all

k = HID_Read()
i = 0
while i < k
ch = userRD_buffer[0]
userWR_buffer[0] =0x01 'sending left click message to test the interface
userWR_buffer[1] =0x00
userWR_buffer[2]=0x00

HID_Write(@userWR_buffer, 3)
inc(i)
wend 

belongs in the main routine in stead of in the interrupt routine...

[Arin_t]

Hi Dany,

Thanks for checking this. I have tested it also in the main routine but still no luck. :(

I am not sure if my descriptor is properly written. Could you please give me your opionion on my descriptor file?

Thanks,
Arin



main:
Init_Main()
read=0


HID_Enable(@userRD_buffer, @userWR_buffer)
'Delay_mS(1000)
Delay_mS(1000)
PORTB=0xff
j=65
while true
k = HID_Read()
i = 0
while i < k
ch = userRD_buffer[0]
userWR_buffer[0] =0x01 'sending left click message to test the interface
userWR_buffer[1] =0x00
userWR_buffer[2]=0x00

HID_Write(@userWR_buffer, 3)
inc(i)
wend
wend
HID_Disable()

end.

[Dany]

Hi,
There is something wrong here:

Code: Select all

dim
k, i, ch ,j ,read as byte
userWR_buffer as byte[3]
userRD_buffer as byte[1]  // <-------- this should also be byte[3] (*)
text as string
temp_res as word 

(*) because of the following:

const HID_OUTPUT_REPORT_BYTES = 3

in the usb descriptor file. I know You want to receive 1 byte each time, but you are getting always 3 (some other -- non receive buffer -- ram memory will be overwritten here). I think however this will not solve your problem.
See also http://users.edpnet.be/rosseel01/DRO/PI ... 0Usage.htm for some tips on usage of the HID library.

I am not sure if my descriptor is properly written. Could you please give me your opionion on my descriptor file?

Did the code already work with a non changed descriptor file? I assume you did change the "report descriptor" part. Until now I used always the same report descriptor content (the "generic" one, with input, output and feature reports), and I do not know how a valid "mouse" device report looks like. I assume there are some examples on the web?

Here is one to be found in document "Universal Serial Bus, Device Class Definition for Human Interface Devices (HID)":

Code: Select all

Do not forget to adapt wDescriptorLength in the HID descriptor to the length of the adapted report.

Hi Dany,

Thanks for the tips. I did check the internet for the hid mouse example and that is how I came up with my new descriptor file. But unfortunately I have not had any success getting it to work.

Here is also another message that once in a while windows pops up:

USB Controller Bandwidth Exceeded

The Controller does not have enough bandwidth available for the USB Human Interface Device.


Thanks,

Dany,

First of all, condradulations on your website. it looks very helpful for beginers like me. ;)

I also wanted to add some more notes here after me working for another several hours on the interface.

Now, when connecting my usb device to my pc, I am geting Windows messgae saying that HID device detected and was properly installed! that's the good news. and the bad news is that I am also getting another message saying that the device cannot start and there is a problem starting it.

if I go to my device manager, I can see my hid device but there is a notification icon on the device and it has the following error:

This device cannot start. (Code 10)
Click Troubleshoot to start the troubleshooter for this device.


I hope this helps. I think the problem is that I do not know how exactly communicate as a mouse.

Here is some part of my new code:

Code: Select all

Hi,
I can not see anything wrong in the reportdescriptor.
But this is probably wrong:

const NUM_ENDPOINTS = 2

because you have only 1 endpoint descriptor (an IN endpoint)... So, the calculation of the total length will be also wrong.

This device cannot start. (Code 10)
Click Troubleshoot to start the troubleshooter for this device.

I have also seen this situation while I was testing my HID library. If I only could remember what the reason was...

Further: in your main code you try to read data coming from the host with "HID_Read()". This will always fail, since a mouse is only capable of sending data to the host (additionally, you have only 1 endpoint -- of IN type --, which can only send data to the host, not receive).

[Arin_t]

Hi Dany,

Sorry for the confusion. In my last descriptor I added another end point OUT. I just thought maybe that's how it should be and therefore I added the following to my descriptor:

Code: Select all

' EP1_TX Descriptor
    0x07, 0,             ' bLength               - length of descriptor (always 0x07)
    0x05, 0,        ' bDescriptorType       - 5 = ENDPOINT descriptor
    0x01, 0,                                ' bEndpointAddress      - out, EP1
    0x03, 0,         ' bmAttributes          - Endpoint Type - Interrupt
    0x08, 0,                 ' wMaxPacketSize        - max packet size - low order byte
    0x00, 0,                '                       - max packet size - high order byte
    0x50, 0,                                  ' bInterval             - polling interval (1 ms)

and added HID_READ to my code.

Please let me know if you found any code that can be helpful on HID mouse communication. I have searched the internet days for any article and code and almost I don't see anything new when I do search. :?

One more thing I was kind of suspisious on my
0x08, 0, ' wMaxPacketSize - max packet size - low

but this is what everywhere they have suggested.


Also please let me know your thoughts on the delay I have in my main loop.

delay_ms(0x20)

should I leave the delay or I need to take it out?



Thanks,

and added HID_READ to my code.

Seems to be fine now.

Ok, I will keep an eye open for it.

One more thing I was kind of suspisious on my

but this is what everywhere they have suggested.

Also that seems to be Ok.

Also please let me know your thoughts on the delay I have in my main loop.
delay_ms(0x20)
should I leave the delay or I need to take it out?

Leaving it in should be no problem.

I am puzzled.

Hi Fabim,

Thaaaaannnnkkkkkkk youuuu!!!!! YOU MADE MY DAY MAN

IT IS WORKING NOW!!!!!!!!!!!!!!!!!!!!!!


Dave, also thanks very much for all your help.

I think this is the first descriptor for mouse I see really is working on the internet.


Time to drink some beer
