This project is part of the Google Summer of Code 2009 project.

Public Roadmap git repository

• http://github.com/tomers/Rockbox-USB-stack-enhancement/tree/hid

Phase 1 (50%):

Type the following command in order to clone the git repository:

• Implement a working HID class driver
• Write a HID test application (control volume of the host)

$ git clone git://github.com/tomers/Rockbox-USB-stack-enhancement.git Phase 2 (50%):

Project Plan

• Separate class driver from main binary, and implement infrastructure to dynamically load them

• Implement a working HID class driver
• Write a HID test application (control volume of the host)
• Separate class driver from main binary, and implement infrastructure to dynamically load them

Currently working on: Phase 1

Currently working on: Implement HID class driver

Remaining work for completing phase 1:

• Configure keymaps for all platforms that uses the Rockbox USB stack (FS#10218)
• Implement a sample application that sends various key codes to the host, e.g. use Rockbox as a PowerPoint Presenter (but not cordless, of course)

Completed (and committed) tasks:

• Switch to git repository management, to ease development process
• Valid enumeration of the DAP as a Human-Interface Device
• Implement support for Interrupt transfers in Sansa e200
• Add debug menu items to control volume (VolUp/VolDown/Mute) on the host using HID messages
• Successfully send HID messages to host.

Other ideas for leveraging this work, which will not be implemented as part of this GSoC project:

• Implement Interrupt type endpoints in all other drivers
• Implement context menu to control the class driver, e.g. key-mappings (code pages), etc.
• Implement 'code-page' to configure key-mapping for controlling Power-Point presentations
• Make touch-screen enabled platforms identify as a tablet device, enabling the player to act as a touch-pad
• Use touchscreen platforms as a LCD keyboard
• Contol what is displayed on the DAP's LCD via a driver run on the host OS

Resources:

Progress:

• Valid enumeration of the DAP as a Human-Interface Device (Committed).
• Implement support for Interrupt transfers in Sansa e200 (Committed).
• Add debug menu items to control volume (VolUp/VolDown/Mute) on the host using HID messages (Done. Not yet committed).

Remaining work for current phase:

• Switch to git repository management, to ease development process (done).
• Successfully send HID messages to host (done).
• Implement sample plugin application that sends various key-strokes to host: Volume control, Mouse control, System control (reboot, shutdown), etc.

Future enhancements (not part of this project):

• Make touch-screen enabled platforms identify as a tablet device, enabling the player to act as a touch-pad.
• Implement context menu to control the class driver, e.g. key-mappings (code pages), etc.
• Implement 'code-page' to configure key-mapping for controlling Power-Point presentations.
• Implement Interrupt type endpoints in all other drivers.
