New version of library, compatible with esp-idf (after cleanup) can be find here:
https://github.com/chegewara/esp32-usb-v2
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.
To use native USB we need to connect pins 19 and 20 to usb cable or with similar connectors:
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);
In case of using more than 1 USB class in 1 device please make sure there is no conflict between EP numbers and eventuallu use setBaseEP:
- CDC - EP1 and EP2,
- HID - keyboard - EP2, mouse - EP3,
- MSC - EP4,
- WebUSB - EP4,
- MIDI - EP5
- DFU - not required
Issues and PRs are welcome.
I have some basic implementation of USB host which i decided to add. This is still experimental version as i dont know what tpe of design to implement (events or callbacks).
Here is log from MSC host reading files from pendrive:
