##### How to use this driver #####
|
||||
==============================================================================
|
||||
[..]
|
||||
The common HAL driver contains a set of generic and common APIs that can be
|
||||
used by the PPP peripheral drivers and the user to start using the HAL.
|
||||
[..]
|
||||
The HAL contains two APIs categories:
|
||||
(+) Common HAL APIs
|
||||
(+) Services HAL APIs

##### HAL Initialization and Configuration functions #####
|
||||
===============================================================================
|
||||
[..] This section provides functions allowing to:
|
||||
(+) Initialize the Flash interface the NVIC allocation and initial time base
|
||||
clock configuration.
|
||||
(+) De-initialize common part of the HAL.
|
||||
(+) Configure the time base source to have 1ms time base with a dedicated
|
||||
Tick interrupt priority.
|
||||
(++) SysTick timer is used by default as source of time base, but user
|
||||
can eventually implement his proper time base source (a general purpose
|
||||
timer for example or other time source), keeping in mind that Time base
|
||||
duration should be kept 1ms since PPP_TIMEOUT_VALUEs are defined and
|
||||
handled in milliseconds basis.
|
||||
(++) Time base configuration function (HAL_InitTick ()) is called automatically
|
||||
at the beginning of the program after reset by HAL_Init() or at any time
|
||||
when clock is configured, by HAL_RCC_ClockConfig().
|
||||
(++) Source of time base is configured to generate interrupts at regular
|
||||
time intervals. Care must be taken if HAL_Delay() is called from a
|
||||
peripheral ISR process, the Tick interrupt line must have higher priority
|
||||
(numerically lower) than the peripheral interrupt. Otherwise the caller
|
||||
ISR process will be blocked.
|
||||
(++) functions affecting time base configurations are declared as __weak
|
||||
to make override possible in case of other implementations in user file.

*** How to configure Interrupts using CORTEX HAL driver ***
|
||||
===========================================================
|
||||
[..]
|
||||
This section provides functions allowing to configure the NVIC interrupts (IRQ).
|
||||
The Cortex M0+ exceptions are managed by CMSIS functions.
|
||||
(#) Enable and Configure the priority of the selected IRQ Channels.
|
||||
The priority can be 0..3.
|
||||
|
||||
-@- Lower priority values gives higher priority.
|
||||
-@- Priority Order:
|
||||
(#@) Lowest priority.
|
||||
(#@) Lowest hardware priority (IRQn position).
|
||||
|
||||
(#) Configure the priority of the selected IRQ Channels using HAL_NVIC_SetPriority()
|
||||
|
||||
(#) Enable the selected IRQ Channels using HAL_NVIC_EnableIRQ()
|
||||
|
||||
-@- Negative value of IRQn_Type are not allowed.
|
||||
|
||||
*** How to configure Systick using CORTEX HAL driver ***
|
||||
========================================================
|
||||
[..]
|
||||
Setup SysTick Timer for time base.
|
||||
|
||||
(+) The HAL_SYSTICK_Config()function calls the SysTick_Config() function which
|
||||
is a CMSIS function that:
|
||||
(++) Configures the SysTick Reload register with value passed as function parameter.
|
||||
(++) Configures the SysTick IRQ priority to the lowest value (0x03).
|
||||
(++) Resets the SysTick Counter register.
|
||||
(++) Configures the SysTick Counter clock source to be Core Clock Source (HCLK).
|
||||
(++) Enables the SysTick Interrupt.
|
||||
(++) Starts the SysTick Counter.
|
||||
|
||||
(+) You can change the SysTick Clock source to be HCLK_Div8 by calling the macro
|
||||
__HAL_CORTEX_SYSTICKCLK_CONFIG(SYSTICK_CLKSOURCE_HCLK_DIV8) just after the
|
||||
HAL_SYSTICK_Config() function call. The __HAL_CORTEX_SYSTICKCLK_CONFIG() macro is defined
|
||||
inside the stm32g0xx_hal_cortex.h file.
|
||||
|
||||
(+) You can change the SysTick IRQ priority by calling the
|
||||
HAL_NVIC_SetPriority(SysTick_IRQn,...) function just after the HAL_SYSTICK_Config() function
|
||||
call. The HAL_NVIC_SetPriority() call the NVIC_SetPriority() function which is a CMSIS function.
|
||||
|
||||
(+) To adjust the SysTick time base, use the following formula:
|
||||
|
||||
Reload Value = SysTick Counter Clock (Hz) x Desired Time base (s)
|
||||
(++) Reload Value is the parameter to be passed for HAL_SYSTICK_Config() function
|
||||
(++) Reload Value should not exceed 0xFFFFFF

|

* @brief DMA Extension HAL module driver
|
||||
* This file provides firmware functions to manage the following
|
||||
* functionalities of the DMA Extension peripheral:
|
||||
* + Extended features functions
|
||||
*
|
||||
@verbatim
|
||||
==============================================================================
|
||||
##### How to use this driver #####
|
||||
==============================================================================
|
||||
[..]
|
||||
The DMA Extension HAL driver can be used as follows:
|
||||
(+) Configure the DMAMUX Synchronization Block using HAL_DMAEx_ConfigMuxSync function.
|
||||
(+) Configure the DMAMUX Request Generator Block using HAL_DMAEx_ConfigMuxRequestGenerator function.
|
||||
Functions HAL_DMAEx_EnableMuxRequestGenerator and HAL_DMAEx_DisableMuxRequestGenerator can then be used
|
||||
to respectively enable/disable the request generator.
|
||||
|
||||
(+) To handle the DMAMUX Interrupts, the function HAL_DMAEx_MUX_IRQHandler should be called from
|
||||
the DMAMUX IRQ handler i.e DMAMUX1_OVR_IRQHandler.
|
||||
As only one interrupt line is available for all DMAMUX channels and request generators , HAL_DMAEx_MUX_IRQHandler should be
|
||||
called with, as parameter, the appropriate DMA handle as many as used DMAs in the user project
|
||||
(exception done if a given DMA is not using the DMAMUX SYNC block neither a request generator)
|
||||

||||

##### EXTI Peripheral features #####
|
||||
==============================================================================
|
||||
[..]
|
||||
(+) Each Exti line can be configured within this driver.
|
||||
|
||||
(+) Exti line can be configured in 3 different modes
|
||||
(++) Interrupt
|
||||
(++) Event
|
||||
(++) Both of them
|
||||
|
||||
(+) Configurable Exti lines can be configured with 3 different triggers
|
||||
(++) Rising
|
||||
(++) Falling
|
||||
(++) Both of them
|
||||
|
||||
(+) When set in interrupt mode, configurable Exti lines have two diffenrents
|
||||
interrupt pending registers which allow to distinguish which transition
|
||||
occurs:
|
||||
(++) Rising edge pending interrupt
|
||||
(++) Falling
|
||||
|
||||
(+) Exti lines 0 to 15 are linked to gpio pin number 0 to 15. Gpio port can
|
||||
be selected through multiplexer.
|
||||
|
||||
##### How to use this driver #####
|
||||
==============================================================================
|
||||
[..]
|
||||
|
||||
(#) Configure the EXTI line using HAL_EXTI_SetConfigLine().
|
||||
(++) Choose the interrupt line number by setting "Line" member from
|
||||
EXTI_ConfigTypeDef structure.
|
||||
(++) Configure the interrupt and/or event mode using "Mode" member from
|
||||
EXTI_ConfigTypeDef structure.
|
||||
(++) For configurable lines, configure rising and/or falling trigger
|
||||
"Trigger" member from EXTI_ConfigTypeDef structure.
|
||||
(++) For Exti lines linked to gpio, choose gpio port using "GPIOSel"
|
||||
member from GPIO_InitTypeDef structure.
|
||||
|
||||
(#) Get current Exti configuration of a dedicated line using
|
||||
HAL_EXTI_GetConfigLine().
|
||||
(++) Provide exiting handle as parameter.
|
||||
(++) Provide pointer on EXTI_ConfigTypeDef structure as second parameter.
|
||||
|
||||
(#) Clear Exti configuration of a dedicated line using HAL_EXTI_GetConfigLine().
|
||||
(++) Provide exiting handle as parameter.
|
||||
|
||||
(#) Register callback to treat Exti interrupts using HAL_EXTI_RegisterCallback().
|
||||
(++) Provide exiting handle as first parameter.
|
||||
(++) Provide which callback will be registered using one value from
|
||||
EXTI_CallbackIDTypeDef.
|
||||
(++) Provide callback function pointer.
|
||||
|
||||
(#) Get interrupt pending bit using HAL_EXTI_GetPending().
|
||||
|
||||
(#) Clear interrupt pending bit using HAL_EXTI_GetPending().
|
||||
|
||||
(#) Generate software interrupt using HAL_EXTI_GenerateSWI().

* @file stm32g0xx_hal_flash.c

* @author MCD Application Team
|
||||
* @brief FLASH HAL module driver.
|
||||
* This file provides firmware functions to manage the following
|
||||
* functionalities of the internal FLASH memory:
|
||||
* + Program operations functions
|
||||
* + Memory Control functions
|
||||
* + Peripheral Errors functions
|
||||
*
|
||||
@verbatim
|
||||
==============================================================================
|
||||
##### FLASH peripheral features #####
|
||||
==============================================================================
|
||||
|
||||
[..] The Flash memory interface manages CPU AHB I-Code and D-Code accesses
|
||||
to the Flash memory. It implements the erase and program Flash memory operations
|
||||
and the read and write protection mechanisms.
|
||||
|
||||
[..] The Flash memory interface accelerates code execution with a system of instruction
|
||||
prefetch and cache lines.
|
||||
|
||||
[..] The FLASH main features are:
|
||||
(+) Flash memory read operations
|
||||
(+) Flash memory program/erase operations
|
||||
(+) Read / write protections
|
||||
(+) Option bytes programming
|
||||
(+) Prefetch on I-Code
|
||||
(+) 32 cache lines of 4*64 bits on I-Code
|
||||
(+) Error code correction (ECC) : Data in flash are 72-bits word
|
||||
(8 bits added per double word)
|
||||
|
||||
##### How to use this driver #####
|
||||
==============================================================================
|
||||
[..]
|
||||
This driver provides functions and macros to configure and program the FLASH
|
||||
memory of all STM32G0xx devices.
|
||||
|
||||
(#) Flash Memory IO Programming functions:
|
||||
(++) Lock and Unlock the FLASH interface using HAL_FLASH_Unlock() and
|
||||
HAL_FLASH_Lock() functions
|
||||
(++) Program functions: double word and fast program (full row programming)
|
||||
(++) There are two modes of programming:
|
||||
(+++) Polling mode using HAL_FLASH_Program() function
|
||||
(+++) Interrupt mode using HAL_FLASH_Program_IT() function
|
||||
|
||||
(#) Interrupts and flags management functions:
|
||||
(++) Handle FLASH interrupts by calling HAL_FLASH_IRQHandler()
|
||||
(++) Callback functions are called when the flash operations are finished :
|
||||
HAL_FLASH_EndOfOperationCallback() when everything is ok, otherwise
|
||||
HAL_FLASH_OperationErrorCallback()
|
||||
(++) Get error flag status by calling HAL_GetError()
|
||||
|
||||
(#) Option bytes management functions :
|
||||
(++) Lock and Unlock the option bytes using HAL_FLASH_OB_Unlock() and
|
||||
HAL_FLASH_OB_Lock() functions
|
||||
(++) Launch the reload of the option bytes using HAL_FLASH_OB_Launch() function.
|
||||
In this case, a reset is generated
|
||||
|
||||
[..]
|
||||
In addition to these functions, this driver includes a set of macros allowing
|
||||
to handle the following operations:
|
||||
(+) Set the latency
|
||||
(+) Enable/Disable the prefetch buffer
|
||||
(+) Enable/Disable the Instruction cache
|
||||
(+) Reset the Instruction cache
|
||||
(+) Enable/Disable the Flash power-down during low-power run and sleep modes
|
||||
(+) Enable/Disable the Flash interrupts
|
||||
(+) Monitor the Flash flags status

||||

##### GPIO Peripheral features #####
|
||||
==============================================================================
|
||||
[..]
|
||||
(+) Each port bit of the general-purpose I/O (GPIO) ports can be individually
|
||||
configured by software in several modes:
|
||||
(++) Input mode
|
||||
(++) Analog mode
|
||||
(++) Output mode
|
||||
(++) Alternate function mode
|
||||
(++) External interrupt/event lines
|
||||
|
||||
(+) During and just after reset, the alternate functions and external interrupt
|
||||
lines are not active and the I/O ports are configured in input floating mode.
|
||||
|
||||
(+) All GPIO pins have weak internal pull-up and pull-down resistors, which can be
|
||||
activated or not.
|
||||
|
||||
(+) In Output or Alternate mode, each IO can be configured on open-drain or push-pull
|
||||
type and the IO speed can be selected depending on the VDD value.
|
||||
|
||||
(+) The microcontroller IO pins are connected to onboard peripherals/modules through a
|
||||
multiplexer that allows only one peripheral alternate function (AF) connected
|
||||
to an IO pin at a time. In this way, there can be no conflict between peripherals
|
||||
sharing the same IO pin.
|
||||
|
||||
(+) All ports have external interrupt/event capability. To use external interrupt
|
||||
lines, the port must be configured in input mode. All available GPIO pins are
|
||||
connected to the 16 external interrupt/event lines from EXTI0 to EXTI15.
|
||||
|
||||
(+) The external interrupt/event controller consists of up to 28 edge detectors
|
||||
(16 lines are connected to GPIO) for generating event/interrupt requests (each
|
||||
input line can be independently configured to select the type (interrupt or event)
|
||||
and the corresponding trigger event (rising or falling or both). Each line can
|
||||
also be masked independently.
|
||||
|
||||
##### How to use this driver #####
|
||||
==============================================================================
|
||||
[..]
|
||||
(#) Enable the GPIO AHB clock using the following function: __HAL_RCC_GPIOx_CLK_ENABLE().
|
||||
|
||||
(#) Configure the GPIO pin(s) using HAL_GPIO_Init().
|
||||
(++) Configure the IO mode using "Mode" member from GPIO_InitTypeDef structure
|
||||
(++) Activate Pull-up, Pull-down resistor using "Pull" member from GPIO_InitTypeDef
|
||||
structure.
|
||||
(++) In case of Output or alternate function mode selection: the speed is
|
||||
configured through "Speed" member from GPIO_InitTypeDef structure.
|
||||
(++) In alternate mode is selection, the alternate function connected to the IO
|
||||
is configured through "Alternate" member from GPIO_InitTypeDef structure.
|
||||
(++) Analog mode is required when a pin is to be used as ADC channel
|
||||
or DAC output.
|
||||
(++) In case of external interrupt/event selection the "Mode" member from
|
||||
GPIO_InitTypeDef structure select the type (interrupt or event) and
|
||||
the corresponding trigger event (rising or falling or both).
|
||||
|
||||
(#) In case of external interrupt/event mode selection, configure NVIC IRQ priority
|
||||
mapped to the EXTI line using HAL_NVIC_SetPriority() and enable it using
|
||||
HAL_NVIC_EnableIRQ().
|
||||
|
||||
(#) To get the level of a pin configured in input mode use HAL_GPIO_ReadPin().
|
||||
|
||||
(#) To set/reset the level of a pin configured in output mode use
|
||||
HAL_GPIO_WritePin()/HAL_GPIO_TogglePin().
|
||||
|
||||
(#) To lock pin configuration until next reset use HAL_GPIO_LockPin().
|
||||
|
||||
(#) During and just after reset, the alternate functions are not
|
||||
active and the GPIO pins are configured in input floating mode (except JTAG
|
||||
pins).
|
||||
|
||||
(#) The LSE oscillator pins OSC32_IN and OSC32_OUT can be used as general purpose
|
||||
(PC14 and PC15, respectively) when the LSE oscillator is off. The LSE has
|
||||
priority over the GPIO function.
|
||||
|
||||
(#) The HSE oscillator pins OSC_IN/OSC_OUT can be used as
|
||||
general purpose PF0 and PF1, respectively, when the HSE oscillator is off.
|
||||
The HSE has priority over the GPIO function.

##### Peripheral Control functions #####
|

===============================================================================
|

|

[..]
|
||||
*** WakeUp pin configuration ***
|
||||
================================
|
||||
[..]
|
||||
(+) WakeUp pins are used to wakeup the system from Standby mode or
|
||||
Shutdown mode. WakeUp pins polarity can be set to configure event
|
||||
detection on high level (rising edge) or low level (falling edge).
|
||||
|
||||
*** Low Power mode configuration ***
|
||||
=====================================
|
||||
[..]
|
||||
The devices feature 7 low-power modes:
|
||||
(+) Low-power run mode: core and peripherals are running at low frequency.
|
||||
Regulator is in low power mode.
|
||||
(+) Sleep mode: Cortex-M0+ core stopped, peripherals kept running,
|
||||
regulator is main mode.
|
||||
(+) Low-power Sleep mode: Cortex-M0+ core stopped, peripherals kept running
|
||||
and regulator in low power mode.
|
||||
(+) Stop 0 mode: all clocks are stopped except LSI and LSE, regulator is
|
||||
main mode.
|
||||
(+) Stop 1 mode: all clocks are stopped except LSI and LSE, main regulator
|
||||
off, low power regulator on.
|
||||
(+) Standby mode: all clocks are stopped except LSI and LSE, regulator is
|
||||
disable.
|
||||
(+) Shutdown mode: all clocks are stopped except LSE, regulator is
|
||||
disable.
|
||||
|
||||
*** Low-power run mode ***
|
||||
==========================
|
||||
[..]
|
||||
(+) Entry: (from main run mode)
|
||||
(++) set LPR bit with HAL_PWREx_EnableLowPowerRunMode() API after
|
||||
having decreased the system clock below 2 MHz.
|
||||
(+) Exit:
|
||||
(++) clear LPR bit then wait for REGLPF bit to be reset with
|
||||
HAL_PWREx_DisableLowPowerRunMode() API. Only then can the
|
||||
system clock frequency be increased above 2 MHz.
|
||||
|
||||
*** Sleep mode / Low-power sleep mode ***
|
||||
=========================================
|
||||
[..]
|
||||
(+) Entry:
|
||||
The Sleep & Low-power Sleep modes are entered through
|
||||
HAL_PWR_EnterSLEEPMode() API specifying whether or not the regulator
|
||||
is forced to low-power mode and if exit is interrupt or event
|
||||
triggered.
|
||||
(++) PWR_MAINREGULATOR_ON: Sleep mode (regulator in main mode).
|
||||
(++) PWR_LOWPOWERREGULATOR_ON: Low-power Sleep mode (regulator in low
|
||||
power mode). In this case, the system clock frequency must have
|
||||
been decreased below 2 MHz beforehand.
|
||||
(++) PWR_SLEEPENTRY_WFI: Core enters sleep mode with WFI instruction
|
||||
(++) PWR_SLEEPENTRY_WFE: Core enters sleep mode with WFE instruction
|
||||
(+) WFI Exit:
|
||||
(++) Any interrupt enabled in nested vectored interrupt controller (NVIC)
|
||||
(+) WFE Exit:
|
||||
(++) Any wakeup event if cortex is configured with SEVONPEND = 0
|
||||
(++) Interrupt even when disabled in NVIC if cortex is configured with
|
||||
SEVONPEND = 1
|
||||
[..] When exiting the Low-power Sleep mode by issuing an interrupt or a wakeup event,
|
||||
the MCU is in Low-power Run mode.
|
||||
|
||||
*** Stop 0 & Stop 1 modes ***
|
||||
=============================
|
||||
[..]
|
||||
(+) Entry:
|
||||
The Stop modes are entered through the following APIs:
|
||||
(++) HAL_PWR_EnterSTOPMode() with following settings:
|
||||
(+++) PWR_MAINREGULATOR_ON to enter STOP0 mode.
|
||||
(+++) PWR_LOWPOWERREGULATOR_ON to enter STOP1 mode.
|
||||
(+) Exit (interrupt or event-triggered, specified when entering STOP mode):
|
||||
(++) PWR_STOPENTRY_WFI: enter Stop mode with WFI instruction
|
||||
(++) PWR_STOPENTRY_WFE: enter Stop mode with WFE instruction
|
||||
(+) WFI Exit:
|
||||
(++) Any EXTI line (internal or external) configured in interrupt mode
|
||||
with corresponding interrupt enable in NVIC
|
||||
(+) WFE Exit:
|
||||
(++) Any EXTI line (internal or external) configured in event mode if
|
||||
cortex is configured with SEVONPEND = 0
|
||||
(++) Any EXTI line configured in interrupt mode (even if the
|
||||
corresponding EXTI Interrupt vector is disabled in the NVIC) if
|
||||
cortex is configured with SEVONPEND = 0. The interrupt source can
|
||||
be external interrupts or peripherals with wakeup capability.
|
||||
[..] When exiting Stop, the MCU is either in Run mode or in Low-power Run mode
|
||||
depending on the LPR bit setting.
|
||||
|
||||
*** Standby mode ***
|
||||
====================
|
||||
[..] In Standby mode, it is possible to keep backup SRAM content (defined as
|
||||
full SRAM) keeping low power regulator on. This is achievable by setting
|
||||
Ram retention bit calling HAL_PWREx_EnableSRAMRetention API. This increases
|
||||
power consumption.
|
||||
Its also possible to define I/O states using APIs:
|
||||
HAL_PWREx_EnableGPIOPullUp, HAL_PWREx_EnableGPIOPullDown &
|
||||
HAL_PWREx_EnablePullUpPullDownConfig
|
||||
(+) Entry:
|
||||
(++) The Standby mode is entered through HAL_PWR_EnterSTANDBYMode() API, by
|
||||
setting SLEEPDEEP in Cortex control register.
|
||||
(+) Exit:
|
||||
(++) WKUP pin edge detection, RTC event (wakeup, alarm, timestamp),
|
||||
tamper event (internal & external), LSE CSS detection, reset on
|
||||
NRST pin, IWDG reset & BOR reset.
|
||||
[..] Exiting Standby generates a power reset: Cortex is reset and execute
|
||||
Reset handler vector, all registers in the Vcore domain are set to
|
||||
their reset value. Registers outside the VCORE domain (RTC, WKUP, IWDG,
|
||||
and Standby/Shutdown modes control) are not impacted.
|
||||
|
||||
*** Shutdown mode ***
|
||||
======================
|
||||
[..]
|
||||
In Shutdown mode,
|
||||
voltage regulator is disabled, all clocks are off except LSE, RRS bit is
|
||||
cleared. SRAM and registers contents are lost except for backup domain
|
||||
registers.
|
||||
(+) Entry:
|
||||
(++) The Shutdown mode is entered through HAL_PWREx_EnterSHUTDOWNMode() API,
|
||||
by setting SLEEPDEEP in Cortex control register.
|
||||
(+) Exit:
|
||||
(++) WKUP pin edge detection, RTC event (wakeup, alarm, timestamp),
|
||||
