I am creating a firmware for PIC18F4550 with the function of BlinkUSBStatus inside. But when i toggle one of my other LEDs from on to off or vice versa, the blinking LED stops blinking. I am wondering why it will stops blinking.
Actually the purpose of the blinking LED is to indicate the data transferring between the USB device and the PC. But once i toggle my LEDs, it stops blinking.
Anyone have any ideas towards this problem ?
Your replies are most welcome and appreciated.
Below is the code for the BlinkUSBStatus function.
Thank you.

Below is the code for the BlinkUSBStatus function.
Code:
void BlinkUSBStatus(void)
{
static WORD led_count=0;
if(led_count == 0)led_count = 10000U;
led_count--;
if(USBSuspendControl == 1)
{
if(led_count==0)
{
mLED_3_Toggle();
}//end if
}
else
{
if(USBDeviceState == DETACHED_STATE)
{
mLED_3_Off()
}
else if(USBDeviceState == ATTACHED_STATE)
{
mLED_3_On()
}
else if(USBDeviceState == POWERED_STATE)
{
mLED_3_On()
}
else if(USBDeviceState == DEFAULT_STATE)
{
mLED_3_On()
}
else if(USBDeviceState == ADDRESS_STATE)
{
if(led_count == 0)
{
mLED_3_Toggle();
}//end if
}
else if(USBDeviceState == CONFIGURED_STATE)
{
if(led_count==0)
{
mLED_3_Toggle();
}//end if
}
}
}Thank you.
