-  *          functionalities of the Touch Sensing Controller (TSC) peripheral:

-  *           + Initialization and De-initialization

-  *           + Channel IOs, Shield IOs and Sampling IOs configuration

-  *           + Start and Stop an acquisition

-================================================================================

-                       ##### TSC specific features #####

-================================================================================

-  [..]

-  (#) Proven and robust surface charge transfer acquisition principle

-

-  (#) Supports up to 3 capacitive sensing channels per group

-

-  (#) Capacitive sensing channels can be acquired in parallel offering a very good

-      response time

-

-  (#) Spread spectrum feature to improve system robustness in noisy environments

-

-  (#) Full hardware management of the charge transfer acquisition sequence

-

-  (#) Programmable charge transfer frequency

-

-  (#) Programmable sampling capacitor I/O pin

-

-  (#) Programmable channel I/O pin

-

-  (#) Programmable max count value to avoid long acquisition when a channel is faulty

-

-  (#) Dedicated end of acquisition and max count error flags with interrupt capability

-

-  (#) One sampling capacitor for up to 3 capacitive sensing channels to reduce the system

-      components

-

-  (#) Compatible with proximity, touchkey, linear and rotary touch sensor implementation

-

-                          ##### How to use this driver #####

-================================================================================

-  [..]

-    (#) Enable the TSC interface clock using __HAL_RCC_TSC_CLK_ENABLE() macro.

-

-    (#) GPIO pins configuration

-      (++) Enable the clock for the TSC GPIOs using __HAL_RCC_GPIOx_CLK_ENABLE() macro.

-      (++) Configure the TSC pins used as sampling IOs in alternate function output Open-Drain mode,

-           and TSC pins used as channel/shield IOs in alternate function output Push-Pull mode

-           using HAL_GPIO_Init() function.

-

-    (#) Interrupts configuration

-      (++) Configure the NVIC (if the interrupt model is used) using HAL_NVIC_SetPriority()

-           and HAL_NVIC_EnableIRQ() and function.

-

-    (#) TSC configuration

-      (++) Configure all TSC parameters and used TSC IOs using HAL_TSC_Init() function.

-

- [..]   TSC peripheral alternate functions are mapped on AF9.

-

-  *** Acquisition sequence ***

-  ===================================

-  [..]

-    (+) Discharge all IOs using HAL_TSC_IODischarge() function.

-    (+) Wait a certain time allowing a good discharge of all capacitors. This delay depends

-        of the sampling capacitor and electrodes design.

-    (+) Select the channel IOs to be acquired using HAL_TSC_IOConfig() function.

-    (+) Launch the acquisition using either HAL_TSC_Start() or HAL_TSC_Start_IT() function.

-        If the synchronized mode is selected, the acquisition will start as soon as the signal

-        is received on the synchro pin.

-    (+) Wait the end of acquisition using either HAL_TSC_PollForAcquisition() or

-        HAL_TSC_GetState() function or using WFI instruction for example.

-    (+) Check the group acquisition status using HAL_TSC_GroupGetStatus() function.

-    (+) Read the acquisition value using HAL_TSC_GroupGetValue() function.

-

-     *** Callback registration ***

-     =============================================

-

-  [..]

-     The compilation flag USE_HAL_TSC_REGISTER_CALLBACKS when set to 1

-     allows the user to configure dynamically the driver callbacks.

-     Use Functions @ref HAL_TSC_RegisterCallback() to register an interrupt callback.

-

-  [..]

-     Function @ref HAL_TSC_RegisterCallback() allows to register following callbacks:

-       (+) ConvCpltCallback   : callback for conversion complete process.

-       (+) ErrorCallback      : callback for error detection.

-       (+) MspInitCallback    : callback for Msp Init.

-       (+) MspDeInitCallback  : callback for Msp DeInit.

-  [..]

-     This function takes as parameters the HAL peripheral handle, the Callback ID

-     and a pointer to the user callback function.

-

-  [..]

-     Use function @ref HAL_TSC_UnRegisterCallback to reset a callback to the default

-     weak function.

-     @ref HAL_TSC_UnRegisterCallback takes as parameters the HAL peripheral handle,

-     and the Callback ID.

-  [..]

-     This function allows to reset following callbacks:

-       (+) ConvCpltCallback   : callback for conversion complete process.

-       (+) ErrorCallback      : callback for error detection.

-       (+) MspInitCallback    : callback for Msp Init.

-       (+) MspDeInitCallback  : callback for Msp DeInit.

-

-  [..]

-     By default, after the @ref HAL_TSC_Init() and when the state is @ref HAL_TSC_STATE_RESET

-     all callbacks are set to the corresponding weak functions:

-     examples @ref HAL_TSC_ConvCpltCallback(), @ref HAL_TSC_ErrorCallback().

-     Exception done for MspInit and MspDeInit functions that are

-     reset to the legacy weak functions in the @ref HAL_TSC_Init()/ @ref HAL_TSC_DeInit() only when

-     these callbacks are null (not registered beforehand).

-     If MspInit or MspDeInit are not null, the @ref HAL_TSC_Init()/ @ref HAL_TSC_DeInit()

-     keep and use the user MspInit/MspDeInit callbacks (registered beforehand) whatever the state.

-

-  [..]

-     Callbacks can be registered/unregistered in @ref HAL_TSC_STATE_READY state only.

-     Exception done MspInit/MspDeInit functions that can be registered/unregistered

-     in @ref HAL_TSC_STATE_READY or @ref HAL_TSC_STATE_RESET state,

-     thus registered (user) MspInit/DeInit callbacks can be used during the Init/DeInit.

-     Then, the user first registers the MspInit/MspDeInit user callbacks

-     using @ref HAL_TSC_RegisterCallback() before calling @ref HAL_TSC_DeInit()

-     or @ref HAL_TSC_Init() function.

-

-  [..]

-     When the compilation flag USE_HAL_TSC_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.
