+ ================================================================================
+ ##### How to use this driver #####
+ ================================================================================
+ [..]
+ The CORDIC HAL driver can be used as follows:
+
+ (#) Initialize the CORDIC low level resources by implementing the HAL_CORDIC_MspInit():
+ (++) Enable the CORDIC interface clock using __HAL_RCC_CORDIC_CLK_ENABLE()
+ (++) In case of using interrupts (e.g. HAL_CORDIC_Calculate_IT())
+ (+++) Configure the CORDIC interrupt priority using HAL_NVIC_SetPriority()
+ (+++) Enable the CORDIC IRQ handler using HAL_NVIC_EnableIRQ()
+ (+++) In CORDIC IRQ handler, call HAL_CORDIC_IRQHandler()
+ (++) In case of using DMA to control data transfer (e.g. HAL_CORDIC_Calculate_DMA())
+ (+++) Enable the DMA2 interface clock using
+ __HAL_RCC_DMA2_CLK_ENABLE()
+ (+++) Configure and enable two DMA channels one for managing data transfer from
+ memory to peripheral (input channel) and another channel for managing data
+ transfer from peripheral to memory (output channel)
+ (+++) Associate the initialized DMA handle to the CORDIC DMA handle
+ using __HAL_LINKDMA()
+ (+++) Configure the priority and enable the NVIC for the transfer complete
+ interrupt on the two DMA channels.
+ Resort to HAL_NVIC_SetPriority() and HAL_NVIC_EnableIRQ()
+
+ (#) Initialize the CORDIC HAL using HAL_CORDIC_Init(). This function
+ (++) resorts to HAL_CORDIC_MspInit() for low-level initialization,
+
+ (#) Configure CORDIC processing (calculation) using HAL_CORDIC_Configure().
+ This function configures:
+ (++) Processing functions: Cosine, Sine, Phase, Modulus, Arctangent,
+ Hyperbolic cosine, Hyperbolic sine, Hyperbolic arctangent,
+ Natural log, Square root
+ (++) Scaling factor: 1 to 2exp(-7)
+ (++) Width of input data: 32 bits input data size (Q1.31 format) or 16 bits
+ input data size (Q1.15 format)
+ (++) Width of output data: 32 bits output data size (Q1.31 format) or 16 bits
+ output data size (Q1.15 format)
+ (++) Number of 32-bit write expected for one calculation: One 32-bits write
+ or Two 32-bit write
+ (++) Number of 32-bit read expected after one calculation: One 32-bits read
+ or Two 32-bit read
+ (++) Precision: 1 to 15 cycles for calculation (the more cycles, the better precision)
+
+ (#) Four processing (calculation) functions are available:
+ (++) Polling mode: processing API is blocking function
+ i.e. it processes the data and wait till the processing is finished
+ API is HAL_CORDIC_Calculate
+ (++) Polling Zero-overhead mode: processing API is blocking function
+ i.e. it processes the data and wait till the processing is finished
+ A bit faster than standard polling mode, but blocking also AHB bus
+ API is HAL_CORDIC_CalculateZO
+ (++) Interrupt mode: processing API is not blocking functions
+ i.e. it processes the data under interrupt
+ API is HAL_CORDIC_Calculate_IT
+ (++) DMA mode: processing API is not blocking functions and the CPU is
+ not used for data transfer,
+ i.e. the data transfer is ensured by DMA
+ API is HAL_CORDIC_Calculate_DMA
+
+ (#) Call HAL_CORDIC_DeInit() to de-initialize the CORDIC peripheral. This function
+ (++) resorts to HAL_CORDIC_MspDeInit() for low-level de-initialization,
+
+ *** Callback registration ***
+ =============================================
+
+ The compilation define USE_HAL_CORDIC_REGISTER_CALLBACKS when set to 1
+ allows the user to configure dynamically the driver callbacks.
+ Use Function HAL_CORDIC_RegisterCallback() to register an interrupt callback.
+
+ Function HAL_CORDIC_RegisterCallback() allows to register following callbacks:
+ (+) ErrorCallback : Error Callback.
+ (+) CalculateCpltCallback : Calculate complete Callback.
+ (+) MspInitCallback : CORDIC MspInit.
+ (+) MspDeInitCallback : CORDIC MspDeInit.
+ This function takes as parameters the HAL peripheral handle, the Callback ID
+ and a pointer to the user callback function.
+
+ Use function HAL_CORDIC_UnRegisterCallback() to reset a callback to the default
+ weak function.
+ HAL_CORDIC_UnRegisterCallback takes as parameters the HAL peripheral handle,
+ and the Callback ID.
+ This function allows to reset following callbacks:
+ (+) ErrorCallback : Error Callback.
+ (+) CalculateCpltCallback : Calculate complete Callback.
+ (+) MspInitCallback : CORDIC MspInit.
+ (+) MspDeInitCallback : CORDIC MspDeInit.
+
+ By default, after the HAL_CORDIC_Init() and when the state is HAL_CORDIC_STATE_RESET,
+ all callbacks are set to the corresponding weak functions:
+ examples HAL_CORDIC_ErrorCallback(), HAL_CORDIC_CalculateCpltCallback().
+ Exception done for MspInit and MspDeInit functions that are
+ reset to the legacy weak function in the HAL_CORDIC_Init()/ HAL_CORDIC_DeInit() only when
+ these callbacks are null (not registered beforehand).
+ if not, MspInit or MspDeInit are not null, the HAL_CORDIC_Init()/ HAL_CORDIC_DeInit()
+ keep and use the user MspInit/MspDeInit callbacks (registered beforehand)
+
+ Callbacks can be registered/unregistered in HAL_CORDIC_STATE_READY state only.
+ Exception done MspInit/MspDeInit that can be registered/unregistered
+ in HAL_CORDIC_STATE_READY or HAL_CORDIC_STATE_RESET state,
+ thus registered (user) MspInit/DeInit callbacks can be used during the Init/DeInit.
+ In that case first register the MspInit/MspDeInit user callbacks
+ using HAL_CORDIC_RegisterCallback() before calling HAL_CORDIC_DeInit()
+ or HAL_CORDIC_Init() function.
+
+ When The compilation define USE_HAL_CORDIC_REGISTER_CALLBACKS is set to 0 or
+ not defined, the callback registration feature is not available and all callbacks
+ are set to the corresponding weak functions.
