v8.0.0

Features

  • SSD1307 Driver
  • Drivers for SSD1327 and the SSD1351
  • DMA support for the SPI OLED Transport Drivers
  • Configurable timing delay to the CD4021 shift register driver
  • Hardware PWM

Bug Fixes

  • QSPI: Fix for a known instability issue. Resolves intermittent bootup issue where QSPI could set itself to write-protected mode.
  • USB Host: Added USBH MIDI source file to CMakeLists for CMake builds
  • I2C: Fixed issue with I2C4 not working
  • I2C: minor breaking change: Fixed inconsistency of address-shifting of ReadDataAtAddress and WriteDataAtAddress to match the other methods.
  • MIDI: Fixed an unrecoverable crash with UART transport if the input shorted to GND for a full UART frame.
  • System: Fixed inaccurate clock division factor for DelayMs and GetMs to be correct.
  • WavWriter: Fixed bug where the last samples of the recording were not being flushed to the output file.

Other

  • The GPIO/Pin migration has been completed within the library, and the dsy_gpio and dsy_gpio_pin structs are deprecated.
  • Minor improvements to daisy::Color type
  • Added explicit setters/getters to daisy::AnalogControl for the scale/offset values
  • Added status check methods for USB Host
  • Improvements to CMake builds
  • README updated with links to daisy.audio site.
  • Improved documentation, and cleaned up WM8731 driver
  • Added Hardware PWM example
  • Added WavWriter example

Bootloader

  • The included bootloader binaries have been updated to v6.3 - This version integrates the above QSPI changes, and improves the boot-jump sequence for apps running directly from QSPI memory.

Migration

I2C Address Shifting

There was an inconsistency between the generic Read and Write methods that automatically left-shifted the device address by one bit, and the ReadDataAtAddress and WriteDataAtAddress functions that required the user to manually shift the address by one.

The internal devices that were affected by this change have been updated internally so this change will have minimal breaking effects.
Those devices are:

  • PCM3060
  • MCP23x17

To migrate existing code for external device drivers any manual left-shifting of the device address for the ReadDataAtAddress or WriteDataAtAddress functions must be removed.

GPIO and Pin

Any remaining instances of dsy_gpio or dsy_gpio_pin should be converted to the newer GPIO and Pin structs.
The constant pin references for DaisySeed and DaisyPatchSM have both been updated to the new Pin struct.

Objects within libDaisy no longer accept the old types, and will need to be updated in application code.

Here are some examples of how to migrate from the old types to the new types.

//////////////////////////////////////////
// Initialization:
//////////////////////////////////////////
// Old:
dsy_gpio_pin pa1 = {DSY_GPIOA, 1};
dsy_gpio gpio1;
gpio1.mode = DSY_GPIO_OUTPUT_PP;
gpio1.pull = DSY_GPIO_NOPULL;
gpio1.pin = pa1;
dsy_gpio_init(&gpio1);

// New:
Pin pa1 = Pin(PORTA, 1);
GPIO gpio1;
gpio1.Init(pa1, GPIO::Mode::OUTPUT, GPIO::Pull::NOPULL);

//////////////////////////////////////////
// Read
//////////////////////////////////////////
// Old:
uint8_t state = dsy_gpio_read(&gpio1);
// New:
bool state = gpio1.Read();

//////////////////////////////////////////
// Write
//////////////////////////////////////////
// Old:
dsy_gpio_write(&gpio1, 1); // HIGH
dsy_gpio_write(&gpio1, 0); // LOW
// New:
gpio1.Write(true); // HIGH
gpio1.Write(false); // LOW

//////////////////////////////////////////
// Toggle
//////////////////////////////////////////
// Old:
dsy_gpio_toggle(&gpio1);
// New:
gpio1.Toggle();
