Functions
int	main (void)
	Main function. Execution starts here. More...

void	main_cdc_disable (uint8_t port)
	Closes the communication port This is called by CDC interface when USB Host disable it. More...

void main_cdc_disable ( uint8_t port )

Closes the communication port This is called by CDC interface when USB Host disable it.

References main_b_cdc_enable, and uart_close().

bool main_cdc_enable ( uint8_t port )

Called by CDC interface Callback running when USB Host enable CDC interface.

Return values

true	if cdc startup is successfully done

References main_b_cdc_enable, and uart_open().

void main_cdc_set_dtr	(	uint8_t	port,
		bool	b_enable
	)

Save new DTR state to change led behavior. The DTR notify that the terminal have open or close the communication port.

bool main_extra_string ( void )

Example of extra USB string management This feature is available for single or composite device which want implement additional USB string than Manufacture, Product and serial number ID.

Called by UDC when USB Host request a extra string different of this specified in USB device descriptor.

return true, if the string ID requested is know and managed by this functions
