Mouse Support

Cosmos now has mouse support...

... and a sample simple drawing app :)

I'm no artist. Daniel Story will draw better soon ;)

Jammy on 12/5/2009 wrote: And even though I said the VGA is fine, i meant that the mode you used is fine. All the other modes don't work.

To fix this you are going to need to add the "Cosmos.Hardware.Mouse" class into your program, and uncomment the code. here is the class, though i doubt it will format correctly :( public static class Mouse { public static int X, Y; public static MouseState Buttons; public static void Initialize() { //enable mouse WaitSignal(); CPUBus.Write8(0x64, 0xA8); // enable interrupt WaitSignal(); CPUBus.Write8(0x64, 0x20); WaitData(); byte status = (byte)(CPUBus.Read8(0x60) | 2); WaitSignal(); CPUBus.Write8(0x64, 0x60); WaitSignal(); CPUBus.Write8(0x60, status); //default Write(0xF6); Read(); //Acknowledge //Enable the mouse Write(0xF4); Read(); //Acknowledge Interrupts.AddIRQHandler(12, new Interrupts.InterruptDelegate(HandleMouse)); } private static byte Read() { WaitData(); return CPUBus.Read8(0x60); } private static void Write(byte b) { //Wait to be able to send a command WaitSignal(); //Tell the mouse we are sending a command CPUBus.Write8(0x64, 0xD4); //Wait for the final part WaitSignal(); //Finally write CPUBus.Write8(0x60, b); } private static void WaitData() { for (int i = 0; i < 1000 & ((CPUBus.Read8(0x64) & 1) == 1); i++) ; } private static void WaitSignal() { for (int i = 0; i < 1000 & ((CPUBus.Read8(0x64) & 2) != 0); i++) ; } public enum MouseState { None = 0, Left = 1, Right = 2, Middle = 4 } private static byte mouse_cycle = 0; private static int[] mouse_byte = new int[4]; public static void HandleMouse(ref Interrupts.InterruptContext context) { switch (mouse_cycle) { case 0: mouse_byte[0] = CPUBus.Read8(0x60); if ((mouse_byte[0] & 0x8) == 0x8) mouse_cycle++; break; case 1: mouse_byte[1] = CPUBus.Read8(0x60); mouse_cycle++; break; case 2: mouse_byte[2] = CPUBus.Read8(0x60); mouse_cycle = 0; if ((mouse_byte[0] & 0x10) == 0x10) X -= mouse_byte[1] ^ 0xff; else X += mouse_byte[1]; if ((mouse_byte[0] & 0x20) == 0x20) Y += mouse_byte[2] ^ 0xff; else Y -= mouse_byte[2]; if (X < 0) X = 0; else if (X > 319) X = 319; if (Y < 0) Y = 0; else if (Y > 199) Y = 199; Buttons = (MouseState)(mouse_byte[0] & 0x7); break; } } } Make sure that you "using Cosmos.Kernel" and "using Cosmos.Hardware" -I hope this helped, it frustrated me for months until I had to find the problem myself. --------- Bill9603
