4.7.1

What's Changed

• Release 4.7.0. by @mhkline in #35

Full Changelog: 4.7.0...4.7.1

4.7.0

Allow usage of INT2 pin during sensor init.

Full Changelog: 4.6.1...4.7.0

4.6.1

New features

• Add API function for getting info from an instruction pointer directly instead of requiring the device pointer
• (Backend) Allow for disabling measurement queue sanitization. This is not intended for public API usage but as a back-door for certain ASIC firmware plugins.

Full Changelog: 4.5.4...4.6.1

4.5.4

Fix #26 and #32

Full Changelog: 4.5.3...4.5.4

4.5.3

Features

Data validation

• Added two public API functions, ch_enable_data_validation() and ch_data_validation_check(), to help validate data transfer integrity (the API header documents them)
• Soniclib's sample count calculation was changed so that the number of samples received for the same measurement queue configuration may differ by 1 sample.

General

• Support OUTPUT_AUTO clock mode for enabling PMUT external clock with clock power state controlled by ICU ASIC.
  Expose function to measure PMUT frequency, ch_measure_pmut_frequency()

Bug fixes

• Restore PMUT clock power state setting in clock_init() in 'restart' condition. Previously, if the MUTCLK pin was set in output mode and then the sensor was restarted, e.g., to load init firmware for transmit optimization, the power state of the MUTCLK oscillator was not preserved. Now it is preserved.
• The overall length of combined receive instructions is now trimmed to remove excess length that does not result in another sample. This also fixes some issues when the total RX instruction length was on the boundary between two samples, in which some strange behavior could be observed.

4.4.7

• avoid conversion of unsigned long to float in ch_log_append()
• fix issue with icu_init_no_txopt syntax in version header
• fix issue with icu_gpt_display_algo_thresholds()
• various fixes to ch_log module
• update license to TDK 5 clause
• fix issue in double buffer mode where metadata was unexpectedly overwritten
• account for leading count instructions when performing tx optimization
• restore pmut clock configuration when switching to init firmware for TX opt

4.4.1

What's Changed

• Fix comment of chbsp_i2c_mem_write() and chbsp_i2c_mem_write_nb()
• Support double buffer readout mode
• Fix Log internal buffer not handling rollover

4.2.5

What's Changed

• [doc] Fix formatting in migration guide
• CMakeLists : arrange to build Soniclib as a module from a parent project
• Add option : main_fw in cmakelist
• CMakeLists : Add property on main_fw option
• Add warning message about adding a segment of 680 samples

4.2.0

• Initial SonicLib 4.x release. See the migration guide for details on changes from SonicLib 3.x to this version.
