Hi,
I am trying to build a keyboard with Media Button inputs as well. I tried to add consumer HID to the keyboard HID but it does not work.
The thing which i want to know is:
1- How can i differentiate between both Report IDs while sending data to PC via USBD?
2- Is there any easier example which I can modify for this?
3- For some reason, if I add the Report ID (0x85, 0x01, //Report ID=1) to Keyboard HID. The keyboard also does not work.
Following is the new HID which i have added into the keyboard HID section.
0x05, 0x0C, /* Usage Page (Consumer Devices) */\ 0x09, 0x01, /* Usage (Consumer Control) */\ 0xA1, 0x01, /* Collection (Application) */\ 0x05, 0x0C, /* Usage Page (Consumer Devices) */\ 0x15, 0x00, /* Logical Minimum (0) */\ 0x25, 0x01, /* Logical Maximum (1) */\ 0x75, 0x01, /* Report Size (1) */\ 0x95, 0x07, /* Report Count (7) */\ 0x09, 0xB5, /* Usage (Scan Next Track) */\ 0x09, 0xB6, /* Usage (Scan Previous Track) */\ 0x09, 0xB7, /* Usage (Stop) */\ 0x09, 0xCD, /* Usage (Play / Pause) */\ 0x09, 0xE2, /* Usage (Mute) */\ 0x09, 0xE9, /* Usage (Volume Up) */\ 0x09, 0xEA, /* Usage (Volume Down) */\ 0x81, 0x02, /* Input (Data, Variable, Absolute)*/\ 0x95, 0x01, /* Report Count (1) */\ 0x81, 0x01, /* Input (Constant) */\ 0xC0 /* End Collection */\
