Functions | |
Internal functions to manage the USB device enumeration | |
Callbacks used by USB Host Driver (UHD) to notify events | |
void | USBH_notify_connection (bool b_plug) |
Notify device connection or disconnection. | |
void | USBH_notify_sof (bool b_micro) |
Notify each start of frame sent by driver. | |
void | USBH_notify_resume (void) |
Notify that a resume bus occurs A resume can occur after a downstream or an upstream resume. | |
Functions to control the USB host stack | |
void | USBH_start (void) |
Starts the host mode. | |
void | USBH_stop (bool b_id_stop) |
Stops the host mode. | |
void | USBH_suspend (bool b_remotewakeup) |
Suspends a USB line. | |
bool | USBH_is_suspend (void) |
Test if the suspend state is enabled on the USB line. | |
void | USBH_resume (void) |
Resumes the USB line. | |
User functions to manage the devices | |
uint8_t | USBH_get_device_number (void) |
Returns the number of connected devices. | |
char * | USBH_dev_get_string_manufacturer (USBH_device_t *dev) |
Gets the USB string manufacturer from a USB device. | |
char * | USBH_dev_get_string_product (USBH_device_t *dev) |
Gets the USB string product from a USB device. | |
char * | USBH_dev_get_string_serial (USBH_device_t *dev) |
Gets the USB string serial from a USB device. | |
char * | USBH_dev_get_string (USBH_device_t *dev, uint8_t str_id) |
Gets a USB string from a USB device. | |
uint16_t | USBH_dev_get_power (USBH_device_t *dev) |
Gets the maximum consumption of a device (mA). | |
USBH_Speed_t | USBH_dev_get_speed (USBH_device_t *dev) |
Returns the current device speed. | |
bool | USBH_dev_is_high_speed_support (USBH_device_t *dev) |
Tests if the device supports the USB high speed This function can wait the end of a setup request and the timing can be long (1ms to 5s). Thus, do not call it in an interrupt routine. | |
