Detailed Description

Configuration structure of the TinyUSB core.

USB specification mandates self-powered devices to monitor USB VBUS to detect connection/disconnection events. If you want to use this feature, connected VBUS to any free GPIO through a voltage divider or voltage comparator. The voltage divider output should be (0.75 * Vdd) if VBUS is 4.4V (lowest valid voltage at device port). The comparator thresholds should be set with hysteresis: 4.35V (falling edge) and 4.75V (raising edge).

[union]

union { ... } tinyusb_config_t

configuration_descriptor

const uint8_t* tinyusb_config_t::configuration_descriptor

Pointer to a configuration descriptor. If set to NULL, TinyUSB device will use a default configuration descriptor whose values are set in Kconfig

device_descriptor

const tusb_desc_device_t* tinyusb_config_t::device_descriptor

Pointer to a device descriptor. If set to NULL, the TinyUSB device will use a default device descriptor whose values are set in Kconfig

external_phy

bool tinyusb_config_t::external_phy

Should USB use an external PHY

self_powered

bool tinyusb_config_t::self_powered

This is a self-powered USB device. USB VBUS must be monitored.
