CAT1 (PSoC™ 6) Hardware Abstraction Layer (HAL) Release Notes

The CAT1 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.

This library is only supported on the Cortex-M4. It is not compatible with the Cortex-M0+. Any peripherals used by the Cortex-M0+ must be configured using the PDL and reserved on the Cortex-M4 by calling cyhal_hwmgr_reserve(). This ensures the HAL is aware the resource is in use and does not overuse it.

What's Included?

This release of the CAT1 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
  • Quadrature Decoder (QuadDec)
  • RTC

  • System
  • TDM
  • Timer
  • True Random Number Generator (TRNG)
  • UART
  • USB Device
  • WDT

What Changed?

v2.1.0

  • Pre-production support for CAT1B devices
  • Fixed a few bugs in various drivers

v2.0.1

This patch release addresses issues in several drivers:

  • RTC:
    1. Do not use RTOS delay even in RTOS-aware mode, to avoid ordering requirements between RTC and RTOS init.
  • PWM:
    1. Fix incorrect period/duty cycle calculation when a line_n (inverted) output pin is used as the sole, non-inverted PWM output.
  • PWM/Timer/QuadDec
    1. Fix level/edge nature of the source not being honored in cyhal_*_connect_digital.
    2. Add cyhal_*_connect_digital2 API to allow explicitly specifying edge type (rising/falling/both). This supercedes cyhal_connect_digital, which defaults to rising edge when the source is an "edge" signal.

v2.0.0

This major version update includes changes that break API compatibility with prior releases. Each major or breaking change is described below:

  • Clock:
    1. Renamed cyhal_resource_inst_t CYHAL_CLOCK_<name> constants with CYHAL_CLOCK_RSC_<name>. Created new CYHAL_CLOCK_<name> constants of type cyhal_clock_t.
    2. Replaced cyhal_clock_init with cyhal_clock_reserve.
    3. Removed div_type & div_num from cyhal_clock_t.
  • DMA:
    1. cyhal_dma_enable must be called after configuring the DMA, but before a trigger will initiate a transfer
  • Flash:
    1. The data buffer passed to functions must be from SRAM, the driver no longer contains a scratch buffer to copy into.
  • GPIO:
    1. cyhal_gpio_enable_output updated to require a new argument to specify whether the signal is level or edge based.
    2. cyhal_gpio_connect_digital no longer takes the signal type parameter.
    3. cyhal_gpio_register_callback now takes a structure containing details about the callback.
    4. Removed deprecated functions cyhal_gpio_register_irq & cyhal_gpio_irq_enable
  • I2C:
    1. Removed deprecated functions cyhal_i2c_register_irq & cyhal_i2c_irq_enable
  • I2S/TDM:
    1. The mclk GPIO selection is moved into the RX/TX specific pins struct. This allows RX and TX to use separate mclk pins on devices that support this; see the device datasheet for details. For devices which only support a single MCLK pin shared between RX and TX, there is no change in functionality; when calling cyhal_i2s_init or cyhal_tdm_init the same cyhal_gpio_t value should be provided for both RX and TX.
  • PWM:
    1. cyhal_pwm_connect_digital no longer takes the signal type parameter.
    2. cyhal_pwm_init will always produce a non-inverted waveform on the specified pin, even if that pin natively produces an inverted output (for example, the line_compl pins on PSoC™ devices). This improves consistency with the behavior of cyhal_pwm_init_adv.
  • QSPI:
    1. cyhal_qspi_init() function got one additional parameter - shared clock (clk), which will allow users to use multiple HAL drivers which depends on same clock source.
    2. cyhal_qspi_init() now takes ioand ssel pins as pointer to cyhal_qspi_slave_pin_config_t structure, that contain mentioned pins.
    3. cyhal_qspi_slave_select_config function was replaced by cyhal_qspi_slave_configure, which provides possibility to add memory slaves with own data lines (instead of shared data lines and own slave select like it was when cyhal_qspi_slave_select_config has been used). cyhal_qspi_slave_config, as cyhal_qspi_init, takes cyhal_qspi_slave_pin_config_t as parameter.
    4. cyhal_qspi_command_t structure was updated: address.value field removed, data_rate field was added into all command subsections.
    5. Added address parameter to all transfer functions (cyhal_qspi_read, cyhal_qspi_read_async, cyhal_qspi_write, cyhal_qspi_write_async anb cyhal_qspi_transfer).
    6. cyhal_qspi_datarate_t enum was added. Corresponding configuration fields are added into each sub-structure of cyhal_qspi_command_t.
  • SDHC:
    1. cyhal_sdhc_init() and cyhal_sdhc_init_hw() functions got one additional parameter - shared clock (block_clk), which will allow users to use multiple HAL drivers which depends on same clock source.
  • SDIO:
    1. Updated the names of enum cyhal_tranfer_t and its types CYHAL_READ and CYHAL_WRITE to cyhal_sdio_transfer_type_t, CYHAL_SDIO_XFER_TYPE_READ, and CYHAL_SDIO_XFER_TYPE_WRITE, respectively.
    2. Removed deprecated functions cyhal_sdio_register_irq & cyhal_sdio_irq_enable
  • Timer:
    1. cyhal_timer_connect_digital no longer takes the signal type parameter.
  • UART:
    1. cyhal_uart_set_flow_control function was replaced by cyhal_uart_enable_flow_control, which only controls the enablement status of flow control. CTS / RTS pins are now provided via cyhal_uart_init() function.
  • I2C:
    1. The following deprecated functions have been removed: cyhal_i2c_slave_config_write_buff, cyhal_i2c_slave_config_read_buff.
  • Other:
    1. Removed cyhal_deprecated.h, and all associated code. NOTE: This version requires core-lib 1.3.0 or later
