Function Documentation

◆ any_protocol_task_active()

bool usb::any_protocol_task_active ( )

Returns: true if any protocol task is active; false if no protocol task is active

◆ init()

esp_err_t usb::init ( BaseType_t xCoreID )

Create a CDC device on the TinyUSB stack and start various USB and USB protocol tasks. The following protocols are supported:

ULF_DCC_EIN
ULF_DECUP_EIN
ULF_SUSIV2

Return values

ESP_OK Success

◆ rx_task_function()

void usb::rx_task_function ( void * )

Scan the CDC character stream for protocol entry strings. Once a supported string is detected the protocol tasks are resumed and the task suspends itself.

◆ transmit_not_ok()

void usb::transmit_not_ok ( )

◆ transmit_ok()

void usb::transmit_ok ( )

◆ transmit_ping()

void usb::transmit_ping ( )

Transmit device name and semantic version to the CDC device queue.

◆ tx_task_function()

void usb::tx_task_function ( void * )

Receive data from tx_stream_buffer and transmit it to the CDC device queue.
