Media Transfer Protocol Porting Kit |best|

MTP is built on the PTP (Picture Transfer Protocol) standard (ISO 15740) and is used in Android MTP mode, Windows Media Player sync, and automotive USB connectivity. The MTP Porting Kit abstracts USB bulk transport, command/response framing, and object storage management, allowing developers to focus on device-specific media storage and property handling.

Reference implementations that developers can adapt for their specific hardware, saving months of manual protocol coding. Media Transfer Protocol Porting Kit

Implement the following callbacks:

void mtp_send_event(uint16_t event_code, uint32_t param1); MTP is built on the PTP (Picture Transfer

bool mtp_usb_send(const uint8_t* data, uint32_t len); bool mtp_usb_recv(uint8_t* buf, uint32_t timeout_ms); void mtp_usb_attach(void); // Notify host of device availability bool mtp_usb_send(const uint8_t* data

The Media Transfer Protocol Porting Kit is a mature toolset that has evolved over decades. Its feature set covers the vast majority of MTP capabilities.
