- * @brief This file provides firmware functions to manage the following
- * 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
- * + Read acquisition result
- * + Interrupts and flags management
- *
- @verbatim
-================================================================================
- ##### 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.
