## 0.3.0 - 2025-01-06
Firstly, this release switches embassy-nrf to chiptool-based `nrf-pac`
implementations and lots of improvements, but also changes to API like
peripheral and interrupt naming.
Second big change is a refactoring of time driver contract with
embassy-time-driver. From now on, the timer queue is handled by the
time-driver implementation and `generic-queue` feature is provided by
the `embassy-time-queue-utils` crate. Newly required dependencies are
following:
- embassy-time-0.4
- embassy-time-driver-0.2
- embassy-time-queue-utils-0.1
Add support for following NRF chips:
- nRF54L15 (only gpio and timer support)
Support for chip-specific features:
- RESET operations for nrf5340
- POWER operations (system-off and wake-on-field) for nrf52840 and nrf9160
- nfc:
- Adds support for NFC Tag emulator driver
- pwm:
- Fix incorrect pin assignments
- Properly disconnect inputs when pins are set as output
- uart:
- `try_write` support for `BufferedUarte`
- Support for `embedded_io_async` trait
- spim:
- Support SPIM4 peripheral on nrf5340-app
- time:
- Generic refactor of embassy-time-driver API
- Fix for missed executor alarms in certain occasions (issue #3672, PR #3705).
- twim:
- Implement support for transactions
- Remove support for consecutive Read operations due to hardware limitations
## 0.2.0 - 2024-08-05
- Support for NRF chips:
- nrf51
- nrf9151
- Support for new peripherals:
- EGU
- radio - low-level support for IEEE 802.15.4 and BLE via radio peripheral
- Peripheral changes:
- gpio: Drop GPIO Pin generics (API break)
- pdm: Fix gain register value derivation
- pwm:
- Expose `duty` method
- Expose `pwm::PWM_CLK_HZ` and add `is_enabled` method
- Allow specifying OutputDrive for PWM channels
- Fix infinite loop
- spim:
- Reduce trace-level messages ("Copying SPIM tx buffer..")
- Support configuring bit order for bus
- Allow specifying OutputDrive for SPI pins
- Add bounds checks for EasyDMA buffer size
- Implement chunked DMA transfers
- uart:
- Add support for rx- or tx-only BufferedUart
- Implement splitting Rx/Tx
- Add support for handling RX errors
- Miscellaneous changes:
- Add `collapse_debuginfo` to fmt.rs macros.
- Drop `sealed` mod
- nrf52840: Add dcdc voltage parameter to configure REG0 regulator
## 0.1.0 - 2024-01-12
- First release with support for following NRF chips:
- nrf52805
- nrf52810
- nrf52811
- nrf52820
- nrf52832
- nrf52833
- nrf52840
- nrf5340
- nrf9160
