◆ netd_control_xfer_cb()

bool netd_control_xfer_cb	(	uint8_t	rhport,
		uint8_t	stage,
		tusb_control_request_t const *	request
	)

Respond to TinyUSB control requests. At startup transmission of notification packets are done here.

Definition at line 245 of file ecm_rndis_device.c.

◆ netd_deinit()

bool netd_deinit ( void )

Deinit driver

Definition at line 139 of file ecm_rndis_device.c.

◆ netd_init()

void netd_init ( void )

Initialize the driver data structures. Might be called several times.

Definition at line 135 of file ecm_rndis_device.c.

◆ netd_open()

uint16_t netd_open	(	uint8_t	rhport,
		tusb_desc_interface_t const *	itf_desc,
		uint16_t	max_len
	)

Open the USB interface.

parse the USB descriptor TUD_CDC_NCM_DESCRIPTOR for itfnum and endpoints
a specific order of elements in the descriptor is tested.

Note: Actually all of the information could be read directly from itf_desc, because the structure and the values are well known. But we do it this way.

Postcondition

itf_num set
ep_notif, ep_in and ep_out are set
USB interface is open

◆ netd_report()

void netd_report	(	uint8_t *	buf,
		uint16_t	len
	)

Definition at line 123 of file ecm_rndis_device.c.

◆ netd_reset()

void netd_reset ( uint8_t rhport )

Resets the port. In this driver this is the same as netd_init()

Definition at line 143 of file ecm_rndis_device.c.

◆ netd_xfer_cb()

bool netd_xfer_cb	(	uint8_t	rhport,
		uint8_t	ep_addr,
		xfer_result_t	result,
		uint32_t	xferred_bytes
	)

Handle TinyUSB requests to process transfer events.

Definition at line 385 of file ecm_rndis_device.c.

◆ tud_network_can_xmit()

bool tud_network_can_xmit ( uint16_t size )

Check if the glue logic is allowed to call tud_network_xmit(). This function also fetches a next buffer if required, so that tud_network_xmit() is ready for copy and transmission operation.

Definition at line 420 of file ecm_rndis_device.c.

◆ tud_network_init_cb()

void tud_network_init_cb ( void )

◆ tud_network_recv_cb()

bool tud_network_recv_cb	(	const uint8_t *	src,
		uint16_t	size
	)

◆ tud_network_xmit()

void tud_network_xmit	(	void *	ref,
		uint16_t	arg
	)

Put a datagram into a waiting NTB. If currently no transmission is started, then initiate transmission.

Definition at line 427 of file ecm_rndis_device.c.
