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 (in alphabetical order). A big Thank You for your great work!
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.
… has contributed complete PCB layouts for the Diamond power supply unit, a single and 5-channel TRIAC output stage, and French firmware translation. He also supported me in the main board unit layout.
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 finally included into the official Diamond RTOS.
… helped me with many useful hints about DMX512, zero-cross-detection optimization and much, much more. Most of the conversation took place at the EuIRC #mikrocontroller.net channel.
… 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.
… 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.
… permitted me to use her CRC16 implementation for flash consistency checking in Diamond RTOS versions prior to 0.9.0.
… has created the outstanding website mikrocontroller.net which has a great community from which I learned many of the basics of building lighting controllers.
… has written the bootloader that is used for the Semitone Diamond. Only slight modifications were required for controlling the Diamond I/O shift registers.
… did most of the porting work for the Diamond RTOS to support the ATmega644 microcontroller.
