-================================================================================
- ##### OPAMP Peripheral Features #####
-================================================================================
-
- [..] The device integrates 2 operational amplifiers OPAMP1 & OPAMP2
-
- (#) The OPAMP(s) provides several exclusive running modes.
- (++) Standalone mode
- (++) Programmable Gain Amplifier (PGA) modes
- (++) Follower mode
-
- (#) Each OPAMP(s) can be configured in normal and high speed mode.
-
- (#) The OPAMP(s) provide(s) calibration capabilities.
- (++) Calibration aims at correcting some offset for running mode.
- (++) The OPAMP uses either factory calibration settings OR user defined
- calibration (trimming) settings (i.e. trimming mode).
- (++) The user defined settings can be figured out using self calibration
- handled by HAL_OPAMP_SelfCalibrate, HAL_OPAMPEx_SelfCalibrateAll
- (++) HAL_OPAMP_SelfCalibrate:
- (+++) Runs automatically the calibration in 2 steps.
- (90% of VDDA for NMOS transistors, 10% of VDDA for PMOS transistors).
- (As OPAMP is Rail-to-rail input/output, these 2 steps calibration is
- appropriate and enough in most cases).
- (+++) Runs automatically the calibration.
- (+++) Enables the user trimming mode
- (+++) Updates the init structure with trimming values with fresh calibration
- results.
- The user may store the calibration results for larger
- (ex monitoring the trimming as a function of temperature
- for instance)
- (+++) HAL_OPAMPEx_SelfCalibrateAll
- runs calibration of all OPAMPs in parallel to save search time.
-
- (#) Running mode: Standalone mode
- (++) Gain is set externally (gain depends on external loads).
- (++) Follower mode also possible externally by connecting the inverting input to
- the output.
-
- (#) Running mode: Follower mode
- (++) No Inverting Input is connected.
-
- (#) Running mode: Programmable Gain Amplifier (PGA) mode
- (Resistor feedback output)
- (#) The OPAMP(s) output(s) can be internally connected to resistor feedback
- output.
- (#) OPAMP gain can be selected as :
-
- (##) Gain of x2, x4, x8 or x16 for non inverting mode with:
- (+++) VREF- referenced.
- (+++) Filtering on VINM0, VREF- referenced.
- (+++) VINM0 node for bias voltage and VINP0 for input signal.
- (+++) VINM0 node for bias voltage and VINP0 for input signal, VINM1 node for filtering.
-
- (##) Gain of x-1, x-3, x-7 or x-15 for inverting mode with:
- (+++) VINM0 node for input signal and VINP0 for bias.
- (+++) VINM0 node for input signal and VINP0 for bias voltage, VINM1 node for filtering.
-
- (#) The OPAMPs inverting input can be selected according to the Reference Manual
- "OPAMP functional description" chapter.
-
- (#) The OPAMPs non inverting input can be selected according to the Reference Manual
- "OPAMP functional description" chapter.

-
- ##### How to use this driver #####
-================================================================================
- [..]
-
- *** High speed / normal power mode ***
- ============================================
- [..] To run in high speed mode:
-
- (#) Configure the OPAMP using HAL_OPAMP_Init() function:
- (++) Select OPAMP_POWERMODE_HIGHSPEED
- (++) Otherwise select OPAMP_POWERMODE_NORMAL
-
- *** Calibration ***
- ============================================
- [..] To run the OPAMP calibration self calibration:
-
- (#) Start calibration using HAL_OPAMP_SelfCalibrate.
- Store the calibration results.
-
- *** Running mode ***
- ============================================
-
- [..] To use the OPAMP, perform the following steps:
-
- (#) Fill in the HAL_OPAMP_MspInit() to
- (++) Enable the OPAMP Peripheral clock using macro __HAL_RCC_OPAMP_CLK_ENABLE()
- (++) Configure the OPAMP input AND output in analog mode using
- HAL_GPIO_Init() to map the OPAMP output to the GPIO pin.
-
- (#) Registrate Callbacks
- (++) The compilation define USE_HAL_OPAMP_REGISTER_CALLBACKS when set to 1
- allows the user to configure dynamically the driver callbacks.
-
- (++) Use Functions @ref HAL_OPAMP_RegisterCallback() to register a user callback,
- it allows to register following callbacks:
- (+++) MspInitCallback : OPAMP MspInit.
- (+++) MspDeInitCallback : OPAMP MspDeInit.
- This function takes as parameters the HAL peripheral handle, the Callback ID
- and a pointer to the user callback function.
-
- (++) Use function @ref HAL_OPAMP_UnRegisterCallback() to reset a callback to the default
- weak (surcharged) function. It allows to reset following callbacks:
- (+++) MspInitCallback : OPAMP MspInit.
- (+++) MspDeInitCallback : OPAMP MspDeInit.
- (+++) All Callbacks
- (#) Configure the OPAMP using HAL_OPAMP_Init() function:
- (++) Select the mode
- (++) Select the inverting input
- (++) Select the non-inverting input
- (++) If PGA mode is enabled, Select if inverting input is connected.
- (++) Select either factory or user defined trimming mode.
- (++) If the user-defined trimming mode is enabled, select PMOS & NMOS trimming values
- (typically values set by HAL_OPAMP_SelfCalibrate function).
-
- (#) Enable the OPAMP using HAL_OPAMP_Start() function.
-
- (#) Disable the OPAMP using HAL_OPAMP_Stop() function.
-
- (#) Lock the OPAMP in running mode using HAL_OPAMP_Lock() function.
- Caution: On STM32H7, HAL OPAMP lock is software lock only (not
- hardware lock as on some other STM32 devices)
-
- (#) If needed, unlock the OPAMP using HAL_OPAMPEx_Unlock() function.
-
- *** Running mode: change of configuration while OPAMP ON ***
- ============================================
- [..] To Re-configure OPAMP when OPAMP is ON (change on the fly)
- (#) If needed, fill in the HAL_OPAMP_MspInit()
- (++) This is the case for instance if you wish to use new OPAMP I/O
-
- (#) Configure the OPAMP using HAL_OPAMP_Init() function:
- (++) As in configure case, select first the parameters you wish to modify.
-
- (#) Change from high speed mode to normal power mode (& vice versa) requires
- first HAL_OPAMP_DeInit() (force OPAMP OFF) and then HAL_OPAMP_Init().
- In other words, of OPAMP is ON, HAL_OPAMP_Init can NOT change power mode
- alone.
