I am running the CE95394 HID Mouse example from Cypress when the code running main is as follows.
void main()
{
CYGlobalIntEnable; /* Enable Global Interrupts */
USBFS_1_Start(0, USBFS_1_DWR_VDDD_OPERATION); /* Start USBFS Operation/device 0 and with 5V operation */
while(!USBFS_1_bGetConfiguration()); /* Wait for Device to enumerate */
LED_Write(1);
USBFS_1_LoadInEP(1, (uint8 *)Mouse_Data, 3); /* Loads an inital value into EP1 and sends it out to the PC */
for(;;)
{
while(!USBFS_1_bGetEPAckState(1)); /* Wait for ACK before loading data */
USBFS_1_LoadInEP(1, (uint8 *)Mouse_Data, 3); /* Load latest mouse data into EP1 and send to PC */
switch (Delay){ /* Switch statement creates a state machine for mouse movement */
case 128:
Mouse_Data[1] = 5; /* Moves mouse to right */
Mouse_Data[2] = 0; /* Keeps Y static */
break;
case 256:
Mouse_Data[1] = 0; /* Keeps X static */
Mouse_Data[2] = -5; /* Moves mouse down */
break;
case 384:
Mouse_Data[1] = -5; /* Moves mouse to left */
Mouse_Data[2] = 0; /* Keeps Y static */
break;
case 512:
Mouse_Data[1] = 0; /* Keeps X static */
Mouse_Data[2] = 5; /* Moves mouse up */
Delay=0;
break;
default:
break;
}
if(Button_1_Read() == 0) /* Check the button state and load the report with the curren status */
{
Mouse_Data[0] = 0x01; /* Report button 1 is pressed */
}
else
{
Mouse_Data[0] = 0x00; /* Report button 1 is not pressed */
}
Delay++;
}
}
This moves the pointer around the screen in a square about fairly large. I have changed it to 1 and -1, it still isn't as fine as the mouse I use on the desktop. When I run this code it doesn't give me options on the computer to change the sensitivity of this mouse just the optical mouse I am using. Setting the code to 127 and -127 make it jump from corner to corner of the screen. I have seen on other forums where they have changed to the descriptor values and made it work for other platforms I just can't seam to get that one to work here.
