- Add cosmolab.json board configuration - Add cosmolab case in oopsy.js - Add cosmolab mapping in oopsy-objectmappings.txt - Add cosmolab to board selection menu - Add oopsy_cosmolab.maxpat template
- Add component_defs.json with CD4021Switch and other component definitions - Add component_defs_patchsm.json and component_defs_petalsm.json - Add json2daisy.js for JSON-based board configuration - Add daisy_glue.js helper functions These files are required for cosmolab.json and other JSON-based board configurations.
- Add require statements for json2daisy.js and daisy_glue.js - Replace generate_target_struct with json2daisy.generate_header - Use json2daisy.format_map for component mapping - Add 'using json2daisy::Daisy;' in generated C++ code - Add hardware.includes support in Makefile - Add APP_TYPE and petal_sm support in Makefile This enables support for CD4021Switch and other components defined in component_defs.json
…patibility - Update genlib_daisy.h to use hardware.som instead of hardware.seed - Replace sub_board with som pointer - Update component_defs.json to use GPIO::Pull::PULLUP instead of Switch::PULL_UP - Add support for OOPSY_OLD_JSON flag for backward compatibility
- Replace StartRx() with DmaListenStart() for MIDI reception
- Replace Readable()/PopRx() with DMA buffer reading
- Update Pin syntax from {DSY_GPIOB, 7} to Pin(DSY_GPIOB, 7)
- Add MidiRxCallback for DMA circular buffer handling
- Update GateIn: use Pin directly instead of dsy_gpio_pin pointer - Update GateOut: use GPIO class with Config instead of dsy_gpio - Update Switch: use GPIO::Pull::PULLUP instead of Switch::PULL_UP - Fix Pin constructor: use GPIOPort::B instead of DSY_GPIOB
- Replace hardware.seed.AudioSampleRate() with som->AudioSampleRate() - Replace hardware.seed.AudioBlockSize() with som->AudioBlockSize() - Update Switch PULL_UP to GPIO::Pull::PULLUP - Add OOPSY_OLD_JSON compatibility check
…upport - Document all breaking changes and API migrations - Explain why each change was necessary - Add Cosmolab board feature list - Include migration notes and disclaimer - Credit Francesco Mulassano (Faselunare) for the update
