v2.2.0

SPRESENSE v2.2.0 release (2021/05/14)

Summary

New features and feature enhancements

  • [HostIF] Support new feature to communicate via I2C/SPI slave with external host device.

  • [DigitalFilter] Add digital filter library. Within this library, the following two filters have been added.

    • FIR Filter: 4 types of filters: low-pass filter, high-pass filter, band-pass filter, and band-elimination filter using FIR.
    • Decimation Filter: A decimation filter using FIR low-pass filter.

Improved features

  • [Audio] Fix an issue where a warning would occur on WAV playback with 96 kHz(sampling-rate) and 24 bits(sample-bit-length).

  • [Image] Add support for error handling using setjmp/longjmp in the libjpeg sample (jpeg_decorder).

  • [FileSystem] Enhance recoverability from power failure during adding file for SmartFS file system on SPI-Flash.

  • [LTE] Improve network connection stability with LTE

Added example code

  • [Power] Add an example code (power_sleep) of waking up from power-saving sleep mode (Deep/Cold) by RTC alarm.

  • [DigitalFilter] Add an example code (fir_filter) of envelope processing using the H function, which is used to analyze impulse signals associated with machine degradation.

How to get source codes

Summary

Improved features

  • [LTE] Fixed a rare error when using the ifup command to activate LTE.
  • [LTE] Fixed an issue in the NuttShell where an assert would occur if you stopped the LTE Daemon using the "lte_daemon stop" command and then ran the "lte_daemon start" command again within one second.
  • [ASMP] Fixed an issue where an error was not returned when calling the SPK startup API in case of the execution memory was exhausted.
  • [GNSS] Fixed a typo in the GNSS sample Kconfig（Thanks to @slipperyseal）
  • [SCU] The API (seq_open()) of the SCU driver has been improved to return an error code when an invalid value is specified.
  • [UART] The HW Flow control and O_NONBLOCK options are supported by the UART0 driver.
  • [Graphics] API (imageproc_clip_and_resize()) for clipping and resizing YUV images supports the ability to just clip them.
  • [Other] The CXD5247's GPO can now be controlled to set and acquire HiZ status.
