c# - Logitech's LED Illumination SDK is not working with my G502 -


i'm trying logitech's own led sdk working g502, can't. i'm using sdk version 8.82.7, is, of now, recent version. couldn't find on or rest of internet, i'm asking here.

here's logitechgsdk.cs:

using system; using system.collections; using system.runtime.interopservices;  namespace logirgb {      public enum keyboardnames {         esc = 0x01,         f1 = 0x3b,         f2 = 0x3c,         f3 = 0x3d,         f4 = 0x3e,         f5 = 0x3f,         f6 = 0x40,         f7 = 0x41,         f8 = 0x42,         f9 = 0x43,         f10 = 0x44,         f11 = 0x57,         f12 = 0x58,         print_screen = 0x137,         scroll_lock = 0x46,         pause_break = 0x45,         tilde = 0x29,         1 = 0x02,         2 = 0x03,         3 = 0x04,         4 = 0x05,         5 = 0x06,         6 = 0x07,         7 = 0x08,         8 = 0x09,         9 = 0x0a,         0 = 0x0b,         minus = 0x0c,         equals = 0x0d,         backspace = 0x0e,         insert = 0x152,         home = 0x147,         page_up = 0x149,         num_lock = 0x145,         num_slash = 0x135,         num_asterisk = 0x37,         num_minus = 0x4a,         tab = 0x0f,         q = 0x10,         w = 0x11,         e = 0x12,         r = 0x13,         t = 0x14,         y = 0x15,         u = 0x16,         = 0x17,         o = 0x18,         p = 0x19,         open_bracket = 0x1a,         close_bracket = 0x1b,         backslash = 0x2b,         keyboard_delete = 0x153,         end = 0x14f,         page_down = 0x151,         num_seven = 0x47,         num_eight = 0x48,         num_nine = 0x49,         num_plus = 0x4e,         caps_lock = 0x3a,         = 0x1e,         s = 0x1f,         d = 0x20,         f = 0x21,         g = 0x22,         h = 0x23,         j = 0x24,         k = 0x25,         l = 0x26,         semicolon = 0x27,         apostrophe = 0x28,         enter = 0x1c,         num_four = 0x4b,         num_five = 0x4c,         num_six = 0x4d,         left_shift = 0x2a,         z = 0x2c,         x = 0x2d,         c = 0x2e,         v = 0x2f,         b = 0x30,         n = 0x31,         m = 0x32,         comma = 0x33,         period = 0x34,         forward_slash = 0x35,         right_shift = 0x36,         arrow_up = 0x148,         num_one = 0x4f,         num_two = 0x50,         num_three = 0x51,         num_enter = 0x11c,         left_control = 0x1d,         left_windows = 0x15b,         left_alt = 0x38,         space = 0x39,         right_alt = 0x138,         right_windows = 0x15c,         application_select = 0x15d,         right_control = 0x11d,         arrow_left = 0x14b,         arrow_down = 0x150,         arrow_right = 0x14d,         num_zero = 0x52,         num_period = 0x53,     };

my color changing code amounts to

logitechgsdk.logiledinit(); logitechgsdk.logiledsettargetdevice(logitechgsdk.logi_devicetype_all); logitechgsdk.logiledsetlighting(255, 127, 0);

which should set mouse's leds nice orange, in reality nothing. it's worth noting logitech's own samples, included in sdk .zip, not work. can set led color logitech's gaming software, that's not want.

is logitech's sdk broken? if not, can working?

edit: should mention own rgb version of g502.

in code arguments of logitechgsdk.logiledsetlighting(255, 127, 0); incorrect exceed value limitation.

they supposed percentages not rgb values.

enter number between 0 , 100 work.

also replace code:

logitechgsdk.logiledsettargetdevice(logitechgsdk.logi_devicetype_all);

with:

logitechgsdk.logiledsettargetdevice(logitechgsdk.logi_devicetype_rgb);

or remove together.

here example of orange:

logitechgsdk.logiledsetlighting(100, 30, 0);

remember give enough time code initialize.
