****************************************************************************************

*
|

* I2C State Monitoring Functions
|
||||
*
|
||||
****************************************************************************************
|
||||
* This I2C driver provides three different ways for I2C state monitoring
|
||||
* depending on the application requirements and constraints:
|
||||
*
|
||||
*
|
||||
* 1) Basic state monitoring:
|
||||
* Using I2C_CheckEvent() function:
|
||||
* It compares the status registers (SR1, SR2 and SR3) content to a given event
|
||||
* (can be the combination of one or more flags).
|
||||
* It returns SUCCESS if the current status includes the given flags
|
||||
* and returns ERROR if one or more flags are missing in the current status.
|
||||
* - When to use:
|
||||
* - This function is suitable for most applications as well as for startup
|
||||
* activity since the events are fully described in the product reference manual
|
||||
* (RM0016).
|
||||
* - It is also suitable for users who need to define their own events.
|
||||
* - Limitations:
|
||||
* - If an error occurs (ie. error flags are set besides to the monitored flags),
|
||||
* the I2C_CheckEvent() function may return SUCCESS despite the communication
|
||||
* hold or corrupted real state.
|
||||
* In this case, it is advised to use error interrupts to monitor the error
|
||||
* events and handle them in the interrupt IRQ handler.
|
||||
*
|
||||
* @note
|
||||
* For error management, it is advised to use the following functions:
|
||||
* - I2C_ITConfig() to configure and enable the error interrupts (I2C_IT_ERR).
|
||||
* - I2C_IRQHandler() which is called when the I2C interrupts occur.
|
||||
* - I2C_GetFlagStatus() or I2C_GetITStatus() to be called into the
|
||||
* I2C_IRQHandler() function in order to determine which error occurred.
|
||||
* - I2C_ClearFlag() or I2C_ClearITPendingBit() and/or I2C_SoftwareResetCmd()
|
||||
* and/or I2C_GenerateStop() in order to clear the error flag and
|
||||
* source and return to correct communication status.
|
||||
*
|
||||
*
|
||||
* 2) Advanced state monitoring:
|
||||
* Using the function I2C_GetLastEvent() which returns the image of both SR1
|
||||
* & SR3 status registers in a single word (uint16_t) (Status Register 3 value
|
||||
* is shifted left by 8 bits and concatenated to Status Register 1).
|
||||
* - When to use:
|
||||
* - This function is suitable for the same applications above but it allows to
|
||||
* overcome the limitations of I2C_GetFlagStatus() function (see below).
|
||||
* The returned value could be compared to events already defined in the
|
||||
* library (stm8s_i2c.h) or to custom values defined by user.
|
||||
* - This function is suitable when multiple flags are monitored at the same time.
|
||||
* - At the opposite of I2C_CheckEvent() function, this function allows user to
|
||||
* choose when an event is accepted (when all events flags are set and no
|
||||
* other flags are set or just when the needed flags are set like
|
||||
* I2C_CheckEvent() function).
|
||||
* - Limitations:
|
||||
* - User may need to define his own events.
|
||||
* - Same remark concerning the error management is applicable for this
|
||||
* function if user decides to check only regular communication flags (and
|
||||
* ignores error flags).
|
||||
*
|
||||
*
|
||||
* 3) Flag-based state monitoring:
|
||||
* Using the function I2C_GetFlagStatus() which simply returns the status of
|
||||
* one single flag (ie. I2C_FLAG_RXNE ...).
|
||||
* - When to use:
|
||||
* - This function could be used for specific applications or in debug phase.
|
||||
* - It is suitable when only one flag checking is needed (most I2C events
|
||||
* are monitored through multiple flags).
|
||||
* - Limitations:
|
||||
* - When calling this function, the Status register is accessed. Some flags are
|
||||
* cleared when the status register is accessed. So checking the status
|
||||
* of one Flag, may clear other ones.
|
||||
* - Function may need to be called twice or more in order to monitor one
|
||||
* single event.
|
||||
*
|
||||
* For detailed description of Events, please refer to section I2C_Events in
|
||||
* stm8s_i2c.h file.
