The new Legion RGB keyboard support both setting and getting effect..
All communication is done sending a Hid Report over the USB Device (VID/PID: 0x048D/0x9C77), the report has a size of 960 byte.
The report size is always 960 byte, so if the control structure is less than that, fill the remaining space with Zero.
All packet Contain a 4 byte Header
struct Header
{
uint8_t Head = 0x7; //This is always 0x7
uint8_t Operation; //This Set the Operation to Execute
uint8_t PacketSize; //0xC0 when Profile/Brightness or AuraraSync, otherwise the Payload Size if more than 256, put Size%256 here
uint8_t Tail = 0x; //This is always 0x3
}
The Field Operation Can be one of these
enum Operation : uint8_t
{
Profile_Set_1 = 0xC8, //Command to change Profile
EffectChange = 0xCB, //Command to change Effect
Profile_Set_2 = 0xCC, //Command to change Profile
Brightness = 0xCE //Command to Change Brightness
AuroraSendBitmap = 0xA1 //Command to send the aurora bitmap
};
A brightness change packet look like the following
struct BrightnessChange
{
struct Header header; //The main header with Operation set to Brightness (0xCE)
uint8_t Brightness; //Brigtness Value
uint8_t Zero_Pad[955]; //Pad the remaining Byte With Zero
}
A Profile change packet look like the following
struct ProfileChange
{
struct Header header; //The main header with Operation set to Profile_Set_2 (0xCC)
uint8_t Profile; //Profile Value
uint8_t Zero_Pad[955]; //Pad the remaining Byte With Zero
}
Followed by
struct ProfileChange
{
struct Header header; //The main header with Operation set to Profile_Set_1 (0xC8)
uint8_t Profile; //Profile Value
uint8_t Zero_Pad[955]; //Pad the remaining Byte With Zero
}
The Color Data is a Simple 8-8-8 RBG
struct RGB
{
uint8_t R;
uint8_t G;
uint8_t B;
};
A Profile is built by chaining multiple Effect together with the Header:
NO_EFFECT is how many effect you want to send
struct ProfileChange
{
struct Header header; //The main header with Operation set to EffectChange (0xCB)
uint8_t Profile; //Profile Value
uint8_t unk1; //Is always 1
uint8_t unk2; //Is always 1
struct Effect[NO_EFFECT]
}
the Effect Structure look Like the following
struct Effect
{
uint8_t Effect_NO; //the first is 1 and the last is NO_EFFECT
struct EffectHeader EffectHeader;
struct RGBData[EffectHeader.NumRGBDataFollowing]; //RGB Data According to the Effect Header Request
uint8_t No_of_key; //Number of Key to witch apply the effect
uint16_t KeyCode;
}
struct EffectHeader
{
uint8_t Head = 0x6;
uint8_t Param1_Header = 0x1;
Effect Effect;
uint8_t Param2_Header = 0x2;
uint8_t Speed = 0x0;
uint8_t Param3_Header = 0x3;
uint8_t Unknwon2 = 0x0;
uint8_t Param4_Header = 0x4;
Direction Direction;
uint8_t Param5_Header = 0x5;
uint8_t ColorMode;
uint8_t Param6_Header = 0x6;
uint8_t Unknwon5 = 0x0; //Always 0
uint8_t NumRGBDataFollowing;
};
enum Effect : uint8_t
{
Screen_Rainbow = 1,
Rainbow_Wave = 2,
Color_Change = 3,
Color_Pulse = 4,
Color_Wave = 5,
Smoth = 6,
Rain = 7,
Ripple = 8, //Apply to All key, send all 0x65 KeyCode
Audio_bounce_Lighting = 9, //Apply to All key, send all 0x65 KeyCode
Audio_ripple_Lighting = 0xa, //Apply to All key, send all 0x65 KeyCode
Always = 0xb, //NumRGBDataFollowing need to be 1
Type_Lighting = 0xc, //Apply to All key, send all 0x65 KeyCode
Legion_Aurora_Sync = 0xd, //Apply to All key, send all 0x65 KeyCode
};
and color Mode can be
enum ColorMode : uint8_t
{
None = 0x0, //For Effect that don't require a Color
RandomColor = 0x1,
ColorList = 0x2
};
when selecting ColorList, set the EffectHeader.NumRGBDataFollowing accordingly, otherwise is 0
When Working with Legion_Aurora_Sync, you need to periodically send the "bitmap" to display over the keyboard
