Hi everyone
I'm using the 'USB HID' component to program a PC mouse based on data of an accelerometer (MPU-6050). My target is 'ECIO40'.
The movement on the screen and the left and right mouse buttons work very well.
I've already added variables 'Data[3]' and 'Data[4]' and I've assigned them with large, small, positive, negative values but scrolling doens't appear on the screen. I've tried every combination possible with variables 'Data[3]' and 'Data[4]'.
Does anybody know what I'm doing wrong?
I have attached the FC program which I'm using.
Thank you very much!
Simon

Re: Scrolling doesn't work for USB HID (mouse) in FC8
Hi Simon,
I beleive the mouse descriptor we supply is fairly basic and doesn't have a scroll wheel capability. So you will need to use the custom descriptor option instead and enter in your own HID descriptor for a mouse with a scroll wheel.
This tool generates descriptors and should be useful for you.

Let us know how you get on.

Hi Ben
Thank you for your advice, it was very useful!
When I use this descriptor code in FC8, the 2 mouse buttons and the X and Y movement are working perfectly.
When I make these small changes to the code, nothing is working anymore and no scroll wheel function is added.
Attached you van find my settings of the 'USB HID' component.
Should you know what I'm doing wrong?
Thank you,
Simon
