Dependencies: mbed C12832_lcd USBHost USBHostPTP LCD_Menu
mbed PTP hosting library
USB Device Interface: Architecture, Protocols, and Programming Class Project
Goal
Provide a generic PTP library to allow the mBed to host a PTP device
Details
- Main thread configures and displays the Menu system, as Commands are selected in the menu a command value is set.
- MSD thread blocks until a MSd device is connected, If a device is removed it will try to reconnect
- PTP thread blocks until a PTP device ois connected. After connection of device, a session is opened, device information is retriewved, and object handles are recieved. As long as a PTP device is connected, the command value is checked for a non-zero value. when a command code is recieved, the statusFunction is changed from NULL, and the command executed. After execution the command code is cleared.
Project Hardware
- mbed LPC1768 CPU board
- mbed DEV-11695 application board
- USB HUB
- USB Mass Storage Device
- Camera using PTP Protocol
- Three USB Cables (normal mbed connection, connection to USB HUB, and connection to camera)

Known Issues
- Buffer overflow will halt the mbed device after 6 hours of transfers
- Method Transaction is unable to SEND Data Containers
- MSD removal does not change the Data container handler. This should become NULL, when the MSD is removed.
Future Work
- Find the buffer overflow
- Implement a PTP Capture Test.
- Implement send data in method Transaction
- Implement an Opcode decoder
- Add Canon extended PTP support.
