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

probonopd	0d7af29227	Apply PR #4 without Synth_Dexed git submodule ... Credits: @dcoredump PR #4 refers to [Synth_Dexed](https://codeberg.org/dcoredump/Synth_Dexed) `c6e768820cffd2c9db277ebce3faf67b27efb26b` which [does not seem to exist](https://github.com/probonopd/MiniDexed/runs/5204665368?check_suite_focus=true#step:3:11). Hence applying the changes this way.	3 years ago
