Breaking Changes
- qspi: updated from C to C++, and fixed up the API to be cleaner, and simpler to use
- sdram: updated from C to C++
- Create SdramHandle class. Gets rid of configurable pin and hardcodes it instead.
Features
- adc: added initialization mappings for pins ADC1_INP12 (PC2) and ADC1_INP13 (PC3) (Not accessible on Daisy Seed)
- board: added support files for upcoming Daisy Patch SM hardware
- rng: added new Random module that provides access to the hardware True Random Number Generator
- spi: added DMA Transactions (same type of queue system as I2C) to the SPI Handle class.
- util: added new PersistentStorage class for storing/recalling data between power cycles
- util: added new VoctCalibration helper class for calibrating ADC inputs
- seed: added support for Daisy Seed 1.1 (aka Daisy Seed rev5) hardware. Pin-compatible, with same form factor. WM8731 Codec instead of AK4556.
- bootloader: added
program-appmake target to upload code to the daisy bootloader
Bug fixes
- adc: fixed bug with ADC where designs with more than 8 channels AND a mux would halt the ADC.
- sdram: changed SdramTiming.RPDelay to 1 to avoid underflow bug.
Other
- util: added deinits and memory-aware inits for bootloader compatibility

QSPI
DaisySeed hw;
// ...
// Old
hw.qspi_handle.mode = DSY_QSPI_MODE_INDIRECT_POLLING;
dsy_qspi_init(&hw.qspi_handle);
dsy_qspi_erase(address, address + sector_size);
dsy_qspi_write(address, size, (uint8_t*)&some_data);
// New -- qspi mode is automatically handled
hw.qspi.Erase(address, address + sector_size);
hw.qspi.Write(address, size, (uint8_t*)&some_data);Sdram
This is only applicable if you had a seed-level board that needed to initialize external SDRAM.
//Init
//Old:
dsy_gpio_pin *pin_group;
dsy_sdram_handle sdram_handle;
sdram_handle.state = DSY_SDRAM_STATE_ENABLE;
pin_group = sdram_handle.pin_config;
pin_group[DSY_SDRAM_PIN_SDNWE] = dsy_pin(DSY_GPIOH, 5);
dsy_sdram_init(&sdram_handle);
//New:
SdramHandle sdram;
sdram.Init();
