PSoC 6 Hardware Abstraction Layer (HAL) Release Notes

The PSoC 6 Hardware Abstraction Layer (HAL) provides an implementation of the Hardware Abstraction Layer for the PSoC 6 family of chips. This API provides convenience methods for initializing and manipulating different hardware peripherals. Depending on the specific chip being used, not all features may be supported.

What's Included?

This release of the PSoC 6 HAL includes support for the following drivers:

  • ADC
  • Clock
  • Comparator
  • CRC
  • DAC
  • DMA
  • EZ-I2C
  • Flash
  • GPIO
  • Hardware Manager
  • I2C
  • I2S
  • LowPower Timer (LPTimer)
  • OpAmp
  • PDM/PCM
  • Power Management (SysPM)
  • PWM
  • QSPI
  • RTC
  • SDHC
  • SDIO
  • SPI
  • System
  • Timer
  • True Random Number Generator (TRNG)
  • UART
  • USB Device
  • WDT

What Changed?

v1.4.0

  • Renamed library from psoc6hal to mtb-hal-cat1
  • Added support for new PSoC 6 S4 devices
  • Extended clock support for QSPI and SDHC drivers
  • Fixed a few bugs in various drivers
  • Minor documentation updates

v1.3.0

  • Added new Analog Comparator driver
  • Added new OpAmp driver
  • Extended ADC driver
  • Extended DAC driver
  • Extended SPI/QSPI drivers to support multiple slave select signals
  • Fixed SDHC based SDIO cyhal_sdio_is_busy() function to return status immediately instead of waiting until the transfer completes
  • Fixed a few bugs in various drivers
  • Minor update for documentation & branding

v1.2.1

  • Added new option for SysPM driver to support tickless sleep in addition to deepsleep
  • Fixed an issue with deep-sleep wake-up in the SDIO and SDHC drivers that could cause intermittent communication failures
  • Minor bug fixes and documentation improvements

v1.2.0

  • Added new Clock driver
  • Added new SysPM Power Management driver
  • Added new I2S driver
  • Added new PDM/PCM driver
  • Reduced flash memory usage for a number of drivers
  • Improved documentation for a number of drivers
  • Fixed a few bugs in various drivers NOTE: The new SysPM driver needs to be initialized by calling cyhal_syspm_init(). This is done automatically by Board Support Packages version 1.2.0 and later.

v1.1.1

  • Improved documentation for a number of drivers
  • Fixed duplicate symbol definition with PDL 1.4.1 release
  • Minor bug fixes

v1.1.0

  • Added new DMA driver
  • Added new EZ-I2C driver
  • Extended System driver to allow getting information about reset
  • Extended System driver to provide delay functions
  • Updated PWM driver to provide additional configuration options
  • Updated Timer driver to allow reading the current count
  • Updated RTC driver to support Day Light Savings time
  • Updated LP Timer driver to improve performance
  • Minor updates up avoid potential warnings on some toolchains
  • Multiple bug fixes across drivers

v1.0.0

  • Initial release (ADC, CRC, DAC, Flash, GPIO, Hardware Manager, I2C, LP Timer, PWM, QSPI, RTC, SDHC, SDIO, SPI, System, Timer, TRNG, UART, USB Device, WDT)
