Description

Library allows to build USB class devices and to make it usable with minimal effort:

• CDC, communication device class,
• MSC, mass storage class,
• HID, human interface device class: keyboard, mouse, gamepad, generic IN/OUT,
• MIDI, musical instrument digital interface class,
• DFU, device firmware update class,
• WebUSB, its using vendor class to show webusb usage.

Hardware

To use native USB we need to connect pins 19 and 20 to usb cable or with similar connectors:

How to

Library allows to set all values in standard USB device like:

• manufacturer
• product name
• serial number
• revision
• VID and PID

ANYusb device;  // any USB class like HID, MSC, CDC
device.manufacturer(char*);
device.product(char*); // product name
device.serial(char*);  // serial number SN
device.revision(uint16_t); // product revison
device.deviceID(uint16_t VID, uint16_t PID);
device.deviceID(uint16_t* VID, uint16_t* PID);

Known issue

Currently library is not working with vanila arduino-esp32. It is due some tinyusb callbacks cant be overriden and are used by arduino-esp32. To make it works it is required to add __attribute__ ((weak)) in 3 lines in local arduino file: https://github.com/espressif/arduino-esp32/blob/master/cores/esp32/esp32-hal-tinyusb.c#L266 https://github.com/espressif/arduino-esp32/blob/master/cores/esp32/esp32-hal-tinyusb.c#L275 https://github.com/espressif/arduino-esp32/blob/master/cores/esp32/esp32-hal-tinyusb.c#L284
