This is a list of users who have actively contributed to the Semitone Project or who have been in other ways involved in the project.

Ashley Roll

The first CRC16 implementation I used in versions prior to Diamond RTOS 0.9.0 was based on an algorithm by Ashley Roll, used with permission. From version 0.9.0 on the avr-libc implementation of the CRC16 algorithm is used.

Arturo de Carlo

...is one of the users of the Diamond lighting controller. He pointed out that rotary encoder input did not work properly in Diamond RTOS version 0.5.2.

Stephan de Georgio

...is one of the Diamond users. He sent me patches for a mute feature that suspends a single channel as well as for a channel selection flash feature. These patches were rewritten and included into the official Diamond RTOS.

Marc Young

...did most of the porting work for the Diamond RTOS to support the ATmega644 microcontroller.

Mikki Merten

...helped me with many useful hints about DMX512, zero-cross-detection optimisation and much, much more. Most of the conversation took place at the EuIRC #mikrocontroller.net channel.

Andreas Schwarz

...has created the outstanding website mikrocontroller.net which has a great forum where I learned a lot about the basics of building lighting controllers. It's a great community.

Fritz Richter

...is one of the users of the Diamond. He sent me a nice zero-crossing detection circuit schematic for the primary side of the main supply transformer. This example has been adapted and eventually included in the schematics of the Diamond.

Marco Monti

...is one of the Diamond users. He provided me with a complete user interface translation for Italian language support for the Diamond RTOS and with occasional translations for new features.

Mark Hämmerling (me)

...is the initiator and main developer of the Semitone Project.
