USB HID Descriptor settings for the trackpad

[JaMa_1051561]

Hello All,

I am developing software for the Trackpad.

For this i have referred following two examples.

CE195394_HID_Mouse  - In this example 3 Bytes mouse data is sent over USB.  Byte1-Button, Byte2- X data, Byte3- Y data

CE216892 USB-HID Trackpad - In this example algorithm is developed to use trackpad and five bytes data is sent over USB. 

 Byte1- Button Data, Byte2- X data, Byte3 - Y data, Byte4- 0 (Scroll), Byte5 - XY negative sign data.

In this example CE195394_HID_Mouse USB HID Descriptor is available for 3bytes. 

I am using algorithm from this example CE216892 USB-HID Trackpad and descriptor from CE195394_HID_Mouse this example. 

I have to modify the descriptor for five Bytes. Here What item value should I select for XYdirection data.

XYdirection is uint8 variable and values are either 1, 2 & 3.

 if someone has worked on this USB HID Touchpad/Trackpad example please help.

Thank you.

Hi @JaMa_1051561 ,

I see you have already explained the same issue in another community thread of yours -  USB HID Descriptor for Trackpad - Cypress Developer Community  . I suggest you to follow up the already going on discussion in that thread itself. Also, please let us know your related queries there. I will go ahead and close this discussion here then.

Thanks and Regards,
