-  * @author  MCD Application Team
-  * @brief   This file provides firmware functions to manage the following 
-  *          functionalities of the Touch Sensing Controller (TSC) peripheral:
-  *           + Initialization and DeInitialization
-  *           + Channel IOs, Shield IOs and Sampling IOs configuration
-  *           + Start and Stop an acquisition
-  *           + Read acquisition result
-  *           + Interrupts and flags management
-  *

-================================================================================
-                       ##### 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.
-      (++) Configure the alternate function on all the TSC pins using HAL_xxxx() function.
-
-    (#) Interrupts configuration
-      (++) Configure the NVIC (if the interrupt model is used) using HAL_xxx() function.
-
-    (#) TSC configuration
-      (++) Configure all TSC parameters and used TSC IOs using HAL_TSC_Init() function.
-
-  *** 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.
