Rene Stange	6f3f2e12da	Multi-core support (#47) ... * Cleanup Makefile * Update submodule circle-stdlib to v15.12 * System options can be defined cleaner using the "-o" option * Include KY-040 driver from Circle (removed from MiniDexed) * Render sound on secondary CPU core 1 * Enable multi-core support on Raspberry Pi 2-4 * Does still work on the Raspberry Pi 1 with restrictions * Use CSoundBaseDevice::Write() instead overriding GetChunk() * CMiniDexed is not derived from the sound device classes any more * Add option SCREEN_DMA_BURST_LENGTH=1 to relieve bus congestion * Add volume control to MIDI CC and UI * Add CPU full speed support Normally the CPU runs at a reduced speed in bare metal applications. With this update and the setting "fast=true" in the file cmdline.txt, it runs at the full speed. Co-authored-by: probonopd <probonopd@users.noreply.github.com>	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
