Hello,
I would like to show you a tutorial to achieve USB communication using HID protocol.
All what you need is to follow instructions below, then you will just need to do that in your sketch:
Send bytes to the PC:
HID().USBSend(Data_report, REPORT_ID + DATA_SIZE);
Receive bytes from the PC:
if (HID().USBRecv(host_report, RID + HOST_SIZE))
{
if (host_report[0] == FUNCTION_ID)
{
// Do your stuff here
}
}
Instructions:
Download the librairies.zip then
Move librairies\HID.cpp to {Arduino Path}\hardware\arduino\avr\libraries\HID\src
Move librairies\HID.h to {Arduino Path}\hardware\arduino\avr\libraries\HID\src
Move librairies\USBCore.cpp to {Arduino Path}\hardware\arduino\avr\cores\arduino
Move librairies\USBAPI.h to {Arduino Path}\hardware\arduino\avr\cores\arduino
Move librairies\Caterina-Leonardo.hex to {Arduino Path}\hardware\arduino\avr\bootloaders\caterina
The Caterina bootloader is here to avoid long upload sketch to the board.
