* @brief CORTEX HAL module driver.
* This file provides firmware functions to manage the following
* functionalities of the CORTEX:
* + Initialization and de-initialization functions
* + Peripheral Control functions
*
@verbatim
==============================================================================
##### How to use this driver #####
==============================================================================
[..]
*** How to configure Interrupts using CORTEX HAL driver ***
===========================================================
[..]
This section provide 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()
[..]
*** 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 stm32l0xx_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

##### DAC Peripheral features #####
==============================================================================
[..]
*** DAC Channels ***
====================
[..]
The device integrates 1 12-bit Digital Analog Converters:
(#) DAC channel1 with DAC_OUT1 (PA4) as output
*** DAC Triggers ***
====================
[..]
Digital to Analog conversion can be non-triggered using DAC_Trigger_None
and DAC_OUT1/DAC_OUT2 is available once writing to DHRx register.
[..]
Digital to Analog conversion can be triggered by:
(#) External event: EXTI Line 9 (any GPIOx_Pin9) using DAC_Trigger_Ext_IT9.
The used pin (GPIOx_Pin9) must be configured in input mode.
(#) Timers TRGO: TIM2, TIM6 and TIM21
(DAC_Trigger_T2_TRGO, DAC_Trigger_T6_TRGO...)
(#) Software using DAC_Trigger_Software
*** DAC Buffer mode feature ***
===============================
[..]
Each DAC channel integrates an output buffer that can be used to
reduce the output impedance, and to drive external loads directly
without having to add an external operational amplifier.
To enable, the output buffer use
sConfig.DAC_OutputBuffer = DAC_OutputBuffer_Enable;
[..]
(@) Refer to the device datasheet for more details about output
impedance value with and without output buffer.
*** DAC wave generation feature ***
===================================
[..]
Both DAC channels can be used to generate
(#) Noise wave using HAL_DAC_NoiseWaveGenerate()
(#) Triangle wave using HAL_DAC_TriangleWaveGenerate()
*** DAC data format ***
=======================
[..]
The DAC data format can be:
(#) 8-bit right alignment using DAC_ALIGN_8B_R
(#) 12-bit left alignment using DAC_ALIGN_12B_L
(#) 12-bit right alignment using DAC_ALIGN_12B_R
*** DAC data value to voltage correspondence ***
================================================
[..]
The analog output voltage on each DAC channel pin is determined
by the following equation:
DAC_OUTx = VREF+ * DOR / 4095
with DOR is the Data Output Register
VEF+ is the input voltage reference (refer to the device datasheet)
e.g. To set DAC_OUT1 to 0.7V, use
Assuming that VREF+ = 3.3V, DAC_OUT1 = (3.3 * 868) / 4095 = 0.7V
*** DMA requests ***
=====================
[..]
A DMA1 request can be generated when an external trigger (but not
a software trigger) occurs if DMA1 requests are enabled using
HAL_DAC_Start_DMA()
[..]
DMA1 requests are mapped as following:
(#) DAC channel1 : mapped on DMA1 Request9 channel2 which must be
already configured
##### How to use this driver #####
==============================================================================
[..]
(+) DAC APB clock must be enabled to get write access to DAC
registers using HAL_DAC_Init()
(+) Configure DAC_OUTx (DAC_OUT1: PA4) in analog mode.
(+) Configure the DAC channel using HAL_DAC_ConfigChannel() function.
(+) Enable the DAC channel using HAL_DAC_Start() or HAL_DAC_Start_DMA functions

* @file stm32l0xx_hal_dma.c
* @author MCD Application Team
* @version V1.0.0
* @date 22-April-2014
* @brief DMA HAL module driver.
*
* This file provides firmware functions to manage the following
* functionalities of the Direct Memory Access (DMA) peripheral:
* + Initialization/de-initialization functions
* + I/O operation functions
* + Peripheral State functions
*
*
@verbatim
==============================================================================
##### How to use this driver #####
==============================================================================
[..]
(#) Enable and configure the peripheral to be connected to the DMA Channel
(except for internal SRAM / FLASH memories: no initialization is
necessary).
(#) For a given Channel, program the required configuration through the following parameters:
Channel request, Transfer Direction, Source and Destination data formats,
Circular, Normal or peripheral flow control mode, Channel Priority level,
Source and Destination Increment mode using HAL_DMA_Init() function.
*** Polling mode IO operation ***
=================================
[..]
(+) Use HAL_DMA_Start() to start DMA transfer after the configuration of Source
address and destination address and the Length of data to be transferred
(+) Use HAL_DMA_PollForTransfer() to poll for the end of current transfer, in this
case a fixed Timeout can be configured by User depending from his application.
*** Interrupt mode IO operation ***
===================================
[..]
(+) Configure the DMA interrupt priority using HAL_NVIC_SetPriority()
(+) Enable the DMA IRQ handler using HAL_NVIC_EnableIRQ()
(+) Use HAL_DMA_Start_IT() to start DMA transfer after the configuration of
Source address and destination address and the Length of data to be transferred. In this
case the DMA interrupt is configured
(+) Use HAL_DMA_IRQHandler() called under DMA_IRQHandler() Interrupt subroutine
(+) At the end of data transfer HAL_DMA_IRQHandler() function is executed and user can
add his own function by customization of function pointer XferCpltCallback and
XferErrorCallback (i.e a member of DMA handle structure).
(#) Use HAL_DMA_GetState() function to return the DMA state and HAL_DMA_GetError() in case of error
detection.
(#) Use HAL_DMA_Abort() function to abort the current transfer
-@- In Memory-to-Memory transfer mode, Circular mode is not allowed.

* @date 22-April-2014
* @brief FLASH HAL module driver.
* This file provides firmware functions to manage the following
* functionalities of the internal FLASH memory:
* + FLASH Interface configuration
* + FLASH Memory Programming
* + DATA EEPROM Programming
* + Option Bytes Programming
* + Interrupts and flags management
*
* @verbatim
==============================================================================
##### FLASH peripheral features #####
==============================================================================
[..] The Flash memory interface manages CPU accesses to the Flash memory.
It implements the erase and program Flash memory operations
and the read and write protection mechanisms.
[..] The FLASH main features are:
(+) Flash memory read operations
(+) Flash memory program/erase operations
(+) Read / write protections
(+) Option Bytes programming
##### How to use this driver #####
==============================================================================
[..]
This driver provides functions and macros to configure and program the FLASH
memory of all STM32L0xx devices.
(#) FLASH Memory IO Programming functions:
(++) Lock and Unlock the FLASH interface using HAL_FLASH_Unlock() and
HAL_FLASH_Lock() functions
(++) Program functions: byte, half word and word
(++) There 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()
(++) Wait for last FLASH operation according to its status
(++) Get error flag status by calling HAL_GetErrorCode()
[..]
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 preread buffer
(+) Enable/Disable the Flash power-down
(+) Enable/Disable the FLASH interrupts
(+) Monitor the FLASH flags status
===============================================================================
##### Programming operation functions #####
===============================================================================
[..]
This subsection provides a set of functions allowing to manage the FLASH
program operations.
[..] The FLASH Memory Programming functions, includes the following functions:
(+) HAL_FLASH_Unlock(void);
(+) HAL_FLASH_Lock(void);
(+) HAL_FLASH_Program(uint32_t TypeProgram, uint32_t Address, uint32_t Data)
(+) HAL_FLASH_Program_IT(uint32_t TypeProgram, uint32_t Address, uint32_t Data)
[..] Any operation of erase or program should follow these steps:
(#) Call the HAL_FLASH_Unlock() function to enable the flash control register and
program memory access.
(#) Call the desired function to erase page or program data.
(#) Call the HAL_FLASH_Lock() to disable the flash program memory access
(recommended to protect the FLASH memory against possible unwanted operation).
==============================================================================
##### Option Bytes Programming functions #####
==============================================================================
[..] The FLASH_Option Bytes Programming_functions, includes the following functions:
(+) HAL_FLASH_OB_Unlock(void);
(+) HAL_FLASH_OB_Lock(void);
(+) HAL_FLASH_OB_Launch(void);
(+) HAL_FLASHEx_OBProgram(FLASH_OBProgramInitTypeDef *pOBInit);
(+) HAL_FLASHEx_OBGetConfig(FLASH_OBProgramInitTypeDef *pOBInit);
[..] Any operation of erase or program should follow these steps:
(#) Call the HAL_FLASH_OB_Unlock() function to enable the Flash option control
register access.
(#) Call the following functions to program the desired option bytes.
(++) HAL_FLASHEx_OBProgram(FLASH_OBProgramInitTypeDef *pOBInit);
(#) Once all needed option bytes to be programmed are correctly written, call the
HAL_FLASH_OB_Launch(void) function to launch the Option Bytes programming process.
(#) Call the HAL_FLASH_OB_Lock() to disable the Flash option control register access (recommended
to protect the option Bytes against possible unwanted operations).
[..] Proprietary code Read Out Protection (PcROP):
(#) The PcROP sector is selected by using the same option bytes as the Write
protection (nWRPi bits). As a result, these 2 options are exclusive each other.
(#) In order to activate the PcROP (change the function of the nWRPi option bits),
the SPRMOD option bit must be activated.
(#) The active value of nWRPi bits is inverted when PCROP mode is active, this
means: if SPRMOD = 1 and nWRPi = 1 (default value), then the user page "i"
is read/write protected.
(#) To activate PCROP mode for Flash page(s), you need to follow the sequence below:
(++) For page(s) within the first 64KB of the Flash, use this function
HAL_FLASHEx_AdvOBProgram with PCROPState = PCROPSTATE_ENABLE.
