Multitouch Usb to Hid over bluetooth

speicherspule

Hey guys, i recently bought a nrf52 DK to implement a gateway between a usb touch monitor to a device such as a android or a computer.my approach is recovering the hid raw frame  with a raspberry pi and send it by uart to the bluetooth module, and put it in the data struture correspondent and send it as hid examples in SDK. 

I can now receive hid raw frame in the nrf52DK as an char array as you can see in the following picture. My code is an adapted code of the uart example of the last SDK, its receiving 124char corresponding to 62byte data frame of my usb hid frame. 

This is my data struture that i got with an hid tool

but now my problem is: how to "fill" my data structure with the data that i'm receiving?

    Hi

    I am a bit confused looking at the struct, and comparing it to the numbers you mention (124 char's and 62 byte data frame). 

    Correct me if I'm wrong, but the struct sets up 12 similar value groups, each 6 bytes in size (3 one bit values, 5 bits of padding, a one byte contact identifier and two bytes each for X and Y). 

    Then at the end there is one additional byte, which means the full struct should be 12*6 + 1 = 73 bytes in size. 

    Are there too many touch points defined in the descriptor?

    Do you have an overview of the content of the 124 char UART packet that you are receiving?
    From the numbers alone it is hard to see how this should match the data structure that you included. 

    Best regards

    Dear Torbjørn, 

    Thank you for quick reply. You're right, the descriptor is wrong. 

    Now we have 

    1byte for report id

    1byte (3bit value + 5 bis of padding)

    2byte x value

    2byte y value

    1 contact identifier byte

    1byte contact counter

    1byte + (1+2+2+1)byte*10 + 1byte =  62 byte

    Hi 

    This definitely makes more sense Slight smile
