probonopd	f784824254	Use the CSoundBaseDevice::Write() method from a secondary CPU core ... Should result in a smaller IRQ latency on CPU core 0 and in a better USB handling. It still works on the RPi 1 too, but the MIDI dump and profiling has to be disabled there, otherwise one will hear drops, when the screen scrolls. https://github.com/probonopd/MiniDexed/issues/39#issuecomment-1062604728 Thanks @rsta2	3 years ago
Rene Stange	7707f90d46	Add initial optional rotary encoder support (#40) ... * Add driver for KY-040 rotary encoder This driver has been taken from the Circle develop branch and can be removed here, when the driver made it up into a circle-stdlib release. * Add initial optional rotary encoder support * Can change between voice and bank select mode by clicking the switch * Turn the knob to select the voice or bank according to current mode * Hold the switch for 3 seconds to reboot the system * Program change from MIDI is only displayed in voice select mode * Configuration for KY-040 added to CConfig and minidexed.ini * Fix: m_I2CMaster has not been initialized in CKernel	3 years ago

Rene Stange	8be0781b49	Restructure code and add new features (#37) ... * Make synth parameters configurable * Add class CConfig, which holds the configuration * Add template config file minidexed.ini * Register panic handler in CKernel to allow to display assertions * Fix: Performance timer did not show correct percent value with HDMI * Add class CDexedAdapter Some Dexed methods require to be guarded from being interrupted by other Dexed calls. This is done in the class CDexedAdapter. * Add class CUserInterface The user interface should be implemented here. As a start it supports showing the program number and name on the LCD display. The LCD output is buffered, so that LCD writes from an IRQ handler are possible. * Move MIDI handling from CMiniDexed to specific classes * CMIDIDevice is the generic MIDI handler * CMIDIKeyboard handles USB audio class MIDI devices * CSerialMIDIDevice handles the serial MIDI device * Now all MIDI inputs can work simultaneous * Program change and bank select work with serial MIDI * Add headers to all files * Include voices.c in sysexfileloader.cpp * Cleanup Makefile * Support headless operation on Raspberry Pi 4 Some code cleanup for src/kernel.* * Code cleanup for src/minidexed.* Move implementation of constructors to minidexed.cpp Reorder member variables * Support multiple USB MIDI inputs at once * Maximum 2 inputs on Raspberry Pi 1-3 * Maximum 4 inputs on Raspberry Pi 4 * Suppress frequent messages in MIDI dump * Use minidexed.txt * Document `SoundDevice` in `minidexed.ini` Co-authored-by: probonopd <probonopd@users.noreply.github.com>	3 years ago

Rene Stange	d5e98e625a	Fix: Invalid handling of .syx file indexes (#34) ... Indexes of voice banks are zero-based now in any case (for the user and internally).
