    • bsp_radio_enable_dma_irq_it()

    • bsp_radio_disable_dma_irq_it()

Changed

  • #defines for interrupt priorities in bsp_def.h were renamed to match our internal naming convention.

  • #defines for DMA_Channelx_IRQn were abstracted with peripherals #defines in bsp_def.h.

  • NVIC_SetPriority and NVIC_EnableIRQ now uses the defines in bsp_def.h, thus making future changes easier and centralized.

  • #defines in bsp_def.h were reordered.

  • Some typedefs were moved from bsp_def.h to bsp_audio.h.

  • DMA1 and DMA2 initialization is now centralized in bsp.c.

  • GPIO clock enabling has been centralized in bsp.c.

  • The return type of some USB functions was changed from uwb_err to uint8_t.

  • bsp_radio_spi_transfer_full_duplex_blocking() does not use the DMA anymore.

  • bsp_audio.h is now included by bsp.h, the public BSP API.

Removed
  • The following functions were removed from the audio module:

    • bsp_audio_init()

    • bsp_audio_deinit()

    • bsp_audio_playback_start()

    • bsp_audio_record_start()

    • bsp_audio_playback_stop()

    • bsp_audio_record_stop()

    • bsp_audio_i2c_write()

    • bsp_audio_i2c_read()

    • bsp_audio_sai_write()

    • bsp_audio_sai_read()

    • bsp_audio_set_playback_channel()

    • bsp_audio_set_record_channel()

    • bsp_audio_set_sampling_rate()

    • bsp_audio_set_rx_callback()

    • bsp_audio_set_tx_callback()

    • bsp_audio_set_error_callback()

    • bsp_audio_config1()

    • bsp_audio_config2()

    • bsp_audio_config3()

  • Some unused includes were removed from bsp_def.h.

Fixed

  • Free running timer that wasn’t providing a 4 kHz tick if system clock was not set to 163.84 MHz.

v0.3.0 - 2021-12-13

Changed

  • Raise STM32 HAL tick interrupt priority one level (from 0x0f to 0x0e) to make it higher priority than the PendSV interrupt which is at 0x0f. This enables calling HAL delay functions inside the PendSV ISR.

  • Functions bsp_audio_sai_read() and bsp_audio_sai_write() size argument is now in bytes instead of in samples.

  • Function bsp_audio_playback_start() now calls audio_tx_callback() instead of sending dummy bytes on the I2S bus.

v0.2.0 - 2021-11-09

Changed

  • STM32 I2S controller role from master to slave.

  • STM32 system clock frequency from 164 MHz to 170 MHz.

Fixed

  • C++ inclusion directives.

  • Wrong call to STM32 HAL RCC when initializing TIM3 timer.

v0.1.0 - 2021-09-30

Initial release.
