*
|

|
* 2) Master Transmitter mode: The master use I2C_SendData() function to send data
|

|
* then to wait on event EVT8 or EVT8_2.
|
||||||
|
* These two events are similar:
|
||||||
|
* - EVT8 means that the data has been written in the data register and is
|
||||||
|
* being shifted out.
|
||||||
|
* - EVT8_2 means that the data has been physically shifted out and output
|
||||||
|
* on the bus.
|
||||||
|
* In most cases, using EVT8 is sufficient for the application.
|
||||||
|
* Using EVT8_2 will leads to a slower communication speed but will more reliable .
|

* EVT8_2 is also more suitable than EVT8 for testing on the last data transmission

|
||||||
|
* In case the user software does not guarantee that this event EVT7 is managed before
|

|
* the current byte end of transfer, then user may check on I2C_EVENT_MASTER_BYTE_RECEIVED

|
||||||
|
* I2C State Monitoring Functions
|
||||||
|
*
|
||||||
|
****************************************************************************************
|
||||||
|
* This I2C driver provides three different ways for I2C state monitoring
|
||||||
|
* profit the application requirements and constraints:
|
||||||
|
*
|
||||||
|
*
|
||||||
|
* a) First way:
|
||||||
|
* Using I2C_CheckEvent() function:
|
||||||
|
* It compares the status registers (STARR1 and STAR2) content to a given event
|
||||||
|
* (can be the combination of more flags).
|
||||||
|
* If the current status registers includes the given flags will return SUCCESS.
|
||||||
|
* and if the current status registers miss flags will returns ERROR.
|
||||||
|
* - 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
|
||||||
|
* (CH32FV2x-V3xRM).
|
||||||
|
* - It is also suitable for users who need to define their own events.
|
||||||
|
* - Limitations:
|
||||||
|
* - If an error occurs besides to the monitored error,
|
||||||
|
* the I2C_CheckEvent() function may return SUCCESS despite the communication
|
||||||
|
* in corrupted state. it is suggeted to use error interrupts to monitor the error
|
||||||
|
* events and handle them in IRQ handler.
|
||||||
|
*
|
||||||
|
*
|
||||||
|
* Note:
|
||||||
|
* The following functions are recommended for error management: :
|
||||||
|
* - I2C_ITConfig() main function of configure and enable the error interrupts.
|
||||||
|
* - I2Cx_ER_IRQHandler() will be called when the error interrupt happen.
|
||||||
|
* Where x is the peripheral instance (I2C1, I2C2 ...)
|
||||||
|
* - I2Cx_ER_IRQHandler() will call I2C_GetFlagStatus() or I2C_GetITStatus() functions
|
||||||
|
* to determine which error occurred.
|
||||||
|
* - I2C_ClearFlag() \ I2C_ClearITPendingBit() \ I2C_SoftwareResetCmd()
|
||||||
|
* \ I2C_GenerateStop() will be use to clear the error flag and source,
|
||||||
|
* and return to correct communication status.
|
||||||
|
*
|
||||||
|
*
|
||||||
|
* b) Second way:
|
||||||
|
* Using the function to get a single word(uint32_t) composed of status register 1 and register 2.
|
||||||
|
* (Status Register 2 value is shifted left by 16 bits and concatenated to Status Register 1).
|
||||||
|
* - When to use:
|
||||||
|
*
|
||||||
|
* - This function is suitable for the same applications above but it
|
||||||
|
* don't have the limitations of I2C_GetFlagStatus() function .
|
||||||
|
* The returned value could be compared to events already defined in the
|
||||||
|
* library (CH32V20x_i2c.h) or to custom values defined by user.
|
||||||
|
* - This function can be used to monitor the status of multiple flags simultaneously.
|
||||||
|
* - Contrary to the I2C_CheckEvent () function, this function can choose the time to
|
||||||
|
* accept the event according to the user's needs (when all event flags are set and
|
||||||
|
* no other flags are set, or only when the required flags are set)
|
||||||
|
*
|
||||||
|
* - 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).
|
||||||
|
*
|
||||||
|
*
|
||||||
|
* c) Third way:
|
||||||
|
* Using the function I2C_GetFlagStatus() get the status of
|
||||||
|
* one single flag .
|
||||||
|
* - 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 .
|
||||||
|
*
|
||||||
|
* - Limitations:
|
||||||
|
* - Call this function to access the status register. Some flag bits may be cleared.
|
||||||
|
* - Function may need to be called twice or more in order to monitor one single event.
