What is Triggercord?

A new project, in early development stage.

A port of pktriggercord[1] to Android.

A tethering application for Pentax K and Samsung GX series DSLRs.

It consists of the pktriggercord based camera interface, a wrapper to a high-level API, and a android program that takes care of user interface.

The high level API is also exposed in python, mostly for testing purposes.

Goals

• Clean, simple user interface
• Support for as many android devices and Pentax K cameras as possible
• Intent-based extensibility

Feature Roadmap

Android compatibility

Android >= 3.1 is required. The device needs to be able to work in USB host mode.

Camera support

pktriggercord, which forms the base for Triggercord's camera interface code, supports most Pentax K mount DSLRs, including Samsung rebadged models, in one form or another[2]. Notable exceptions are early entry-level cameras (K100D, K110D) and the ist series, which are only partially supported.

Triggercord will focus on support for K-5 and newer models.

Support for the latest models (K-30, K-5II, K-5IIs) is yet incomplete.

Known bugs

pktriggercord:

• Pentax K-r ISO can't be changed in M mode
• K-30 support is buggy
• Green button not functional
