Advanced RawHID example
|
|
Shows how to send bytes via raw HID
|
|
Press a button to send some example values.
|
|
Keep in mind that you can only send full data packets, the rest is filled with zero!
|
|
|
|
Definitions from HID_Reports.h:
|
|
RAWHID_USAGE_PAGE 0xFFC0 // recommended: 0xFF00 to 0xFFFF
|
|
RAWHID_USAGE 0x0C00 // recommended: 0x0100 to 0xFFFF
|
|
RAWHID_TX_SIZE 63 // 1 byte for report ID
|
|
RAWHID_RX_SIZE 63 // 1 byte for report ID
|
