Changelog

All notable changes to this project are documented in this file.

[1.8.6] - 2020-08-31

Added

• Implemented workaround for anomaly 223 in the USBD driver.

Changed

• Updated MDK to version 8.35.0.

[1.8.5] - 2020-07-09

Added

• Implemented workaround for anomaly 211 in the USBD driver.

Changed

• Updated MDK to version 8.32.3.

[1.8.4] - 2020-04-27

• Fixed an issue in the NFCT driver where the FIELDDETECTED event would be ignored and the FIELDLOST event would be processed twice. The driver now properly handles FIELDDETECTED and FIELDLOST events.

[1.8.3] - 2020-03-20

Added

• Added documentation pages for nRF52820.
• Added possibility to use the nRF52833 DK in development for nRF52820. LEDs and buttons in this DK use GPIOs that are not present in the actual nRF52820 device, so accesses to these need special handling in the GPIO HAL.

Fixed

• Fixed assertions that check input pin selections in the legacy SAADC driver. Now the VDDHDIV5 setting is handled properly.
• Fixed the number of machine cycles per single delay loop for nRF52820 in the nrfx_coredep module.

[1.8.2] - 2020-03-05

Added

• Added support for nRF52820.
• Added new implementation of the SAADC driver. The new version is enabled when the NRFX_SAADC_API_V2 symbol is defined, otherwise the legacy one is used.
• Introduced the NRFX_TWIM_NO_SPURIOUS_STOP_CHECK flag in the TWIM driver.
• Added function for getting the configuration of shortcuts in the TWIM HAL.
• Implemented workaround for nRF9160 anomaly 23 in the UARTE driver.

Changed

• Updated MDK to version 8.32.1.
• Improved the UARTE driver to consume less current after the driver uninitialization. Now all clocks are disabled properly.
• Improved the GPIOTE driver robustness by setting the LATCH functionality to be used by default.
• Improved handling of spurious STOP condition in the TWIM driver.
• Removed support for revision Engineering A of nRF52840 in the USBD driver.

Fixed

• Fixed assertions that check write addresses in the NVMC driver. Now the UICR memory region is handled properly.
• Fixed an issue in the TWI driver that would make the driver stuck when a premature STOP condition was generated by a slave device. The driver now handles this situation properly and signals that a bus error occurred.
• Fixed the stopping procedure in the PWM driver. Previously in very specific circumstances the PWM output might be not stopped at all or might be immediately restarted.
• Fixed a race condition in the CLOCK driver when requested clock was stopped during ramp-up from high priority interrupt.
• Fixed assertions that check pin numbers in the GPIO HAL and GPIOTE driver. Now noncontiguous groups of available pin numbers are handled properly.

[1.8.1] - 2019-10-21

Added

• Added functions in the GPIOTE driver for getting task or event for the specified GPIO pin.

Changed

• Updated MDK to version 8.27.1.
• Moved the nrfx_gppi helper from helpers/nrfx_gppi/ to helpers/.
• Changed the interrupt initialization in the GPIOTE driver, so that mapping of the GPIOTEx_IRQn enumeration values is no longer needed for nRF9160.

[1.8.0] - 2019-08-27

Added

• Added support for nRF52833.
• Added bus recovery feature in the TWI and TWIM drivers.
• Added the nrfx_gppi helper layer to facilitate developing generic code that can utilize PPI or DPPI, depending on which interface is available in a given SoC.

Changed

• Updated MDK to version 8.27.0.

Fixed

• Fixed an issue in the TWIM driver that would make the driver stuck when a premature STOP condition was generated by a slave device. The driver now handles this situation properly and signals that a bus error occurred.
• Fixed a frame timing bug in the NFCT driver. Previously, the timing of the SENS_RES response could be violated after the NFCT peripheral was put to the Sleep state with the SLP_REQ command.

[1.7.2] - 2019-07-25

Added

• Added functions in the DPPI, GPIOTE, PPI, RTC, and TIMER HALs for getting tasks and events specified by index.
• Added the possibility of suspending transfers in the TWI driver. This allows combining several transfers into one continuous TWI transaction.
• Added termination of transfers at deinitialization of the UARTE driver.
• Added buffer alignment checks in the QSPI driver.
• Introduced the NRFX_OFFSETOF macro that duplicates the functionality of the built-in offsetof() mechanism, but can be used without issues also with non-constant expressions.
• Added an alternative way of ending the DMA transfer loop in the USBD driver.
• Added the CTSTARTED and CTSTOPPED events to the CLOCK HAL.

Changed

• Removed an assertion that prevented setting the data payload size of isochronous endpoints to zero, to fulfill requirements of the USB 2.0 specification, paragraph 5.6.3.
• Declared the tx_buffer_length field in the UART driver's control block as volatile to prevent issues in case of compilation with high optimization level.

Fixed

• Fixed an incorrect conversion of frequency values in the RADIO HAL.

Added

• Added drivers for NVMC and TEMP.

• Improved the UARTE driver to consume less current after the TX operation. Now at the end of the transmission the transmitter is turned off by the STOPTX task.
• Improved C++ support in drivers. Now fields in structures are filled up in the correct order.
• Changed to size_t the type used for holding the amount of data in the TWIS driver.

Fixed

• Fixed a race condition in the USBD driver. It could occur when an IN transfer was interrupted by an OUT transaction, which in turn was interrupted by a process with a higher priority.

[1.6.2] - 2019-02-12

Added

• Added the possibility to use the macro NRFX_COREDEP_DELAY_US_LOOP_CYCLES to specify the number of cycles consumed by one iteration of the internal loop in the function nrfx_coredep_delay_us().
