int main ( void  )
void main_cdc_disable ( uint8_t  port)

bool main_cdc_enable ( uint8_t  port)

Opens the communication port This is called by CDC interface when USB Host enable it.

Return values
trueif cdc startup is successfully done

void main_resume_action ( void  )

Called by UDD when the USB line exit of suspend state.

Turn on a led to notify active mode Called when the USB line is resumed from the suspend state.

References ui_wakeup().

void main_sof_action ( void  )

Called when a start of frame is received on USB line.

void main_suspend_action ( void  )

Enters the application in low power mode Callback called when USB host sets USB line in suspend state.

Turn off all leds Callback running when USB Host set USB line in suspend state.

Called by UDD when a suspend is received Callback running when USB Host set USB line in suspend state.
