* @brief I2C HAL module driver.
* This file provides firmware functions to manage the following
* functionalities of the Inter Integrated Circuit (I2C) peripheral:
* + Initialization and de-initialization functions
* + IO operation functions
* + Peripheral State, Mode and Error functions
*
@verbatim
==============================================================================
##### How to use this driver #####
==============================================================================
[..]
The I2C HAL driver can be used as follows:
(#) Declare a I2C_HandleTypeDef handle structure, for example:
I2C_HandleTypeDef hi2c;
(#)Initialize the I2C low level resources by implementing the @ref HAL_I2C_MspInit() API:
(##) Enable the I2Cx interface clock
(##) I2C pins configuration
(+++) Enable the clock for the I2C GPIOs
(+++) Configure I2C pins as alternate function open-drain
(##) NVIC configuration if you need to use interrupt process
(+++) Configure the I2Cx interrupt priority
(+++) Enable the NVIC I2C IRQ Channel
(##) DMA Configuration if you need to use DMA process
(+++) Declare a DMA_HandleTypeDef handle structure for the transmit or receive channel
(+++) Enable the DMAx interface clock using
(+++) Configure the DMA handle parameters
(+++) Configure the DMA Tx or Rx channel
(+++) Associate the initialized DMA handle to the hi2c DMA Tx or Rx handle
(+++) Configure the priority and enable the NVIC for the transfer complete interrupt on
the DMA Tx or Rx channel
(#) Configure the Communication Speed, Duty cycle, Addressing mode, Own Address1,
Dual Addressing mode, Own Address2, General call and Nostretch mode in the hi2c Init structure.
(#) Initialize the I2C registers by calling the @ref HAL_I2C_Init(), configures also the low level Hardware
(GPIO, CLOCK, NVIC...etc) by calling the customized @ref HAL_I2C_MspInit() API.
(#) To check if target device is ready for communication, use the function @ref HAL_I2C_IsDeviceReady()
(#) For I2C IO and IO MEM operations, three operation modes are available within this driver :
*** Polling mode IO operation ***
=================================
[..]
(+) Transmit in master mode an amount of data in blocking mode using @ref HAL_I2C_Master_Transmit()
(+) Receive in master mode an amount of data in blocking mode using @ref HAL_I2C_Master_Receive()
(+) Transmit in slave mode an amount of data in blocking mode using @ref HAL_I2C_Slave_Transmit()
(+) Receive in slave mode an amount of data in blocking mode using @ref HAL_I2C_Slave_Receive()
*** Polling mode IO MEM operation ***
=====================================
[..]
(+) Write an amount of data in blocking mode to a specific memory address using @ref HAL_I2C_Mem_Write()
(+) Read an amount of data in blocking mode from a specific memory address using @ref HAL_I2C_Mem_Read()
*** Interrupt mode IO operation ***
===================================
[..]
(+) Transmit in master mode an amount of data in non-blocking mode using @ref HAL_I2C_Master_Transmit_IT()
(+) At transmission end of transfer, @ref HAL_I2C_MasterTxCpltCallback() is executed and user can
add his own code by customization of function pointer @ref HAL_I2C_MasterTxCpltCallback()
(+) Receive in master mode an amount of data in non-blocking mode using @ref HAL_I2C_Master_Receive_IT()
(+) At reception end of transfer, @ref HAL_I2C_MasterRxCpltCallback() is executed and user can
add his own code by customization of function pointer @ref HAL_I2C_MasterRxCpltCallback()
(+) Transmit in slave mode an amount of data in non-blocking mode using @ref HAL_I2C_Slave_Transmit_IT()
(+) At transmission end of transfer, @ref HAL_I2C_SlaveTxCpltCallback() is executed and user can
add his own code by customization of function pointer @ref HAL_I2C_SlaveTxCpltCallback()
(+) Receive in slave mode an amount of data in non-blocking mode using @ref HAL_I2C_Slave_Receive_IT()
(+) At reception end of transfer, @ref HAL_I2C_SlaveRxCpltCallback() is executed and user can
add his own code by customization of function pointer @ref HAL_I2C_SlaveRxCpltCallback()
(+) In case of transfer Error, @ref HAL_I2C_ErrorCallback() function is executed and user can
add his own code by customization of function pointer @ref HAL_I2C_ErrorCallback()
(+) Abort a master I2C process communication with Interrupt using @ref HAL_I2C_Master_Abort_IT()
(+) End of abort process, @ref HAL_I2C_AbortCpltCallback() is executed and user can
add his own code by customization of function pointer @ref HAL_I2C_AbortCpltCallback()
*** Interrupt mode or DMA mode IO sequential operation ***
==========================================================
[..]
(@) These interfaces allow to manage a sequential transfer with a repeated start condition
when a direction change during transfer
[..]
(+) A specific option field manage the different steps of a sequential transfer
(+) Option field values are defined through @ref I2C_XferOptions_definition and are listed below:
(++) I2C_FIRST_AND_LAST_FRAME: No sequential usage, functionnal is same as associated interfaces in no sequential mode
(++) I2C_FIRST_FRAME: Sequential usage, this option allow to manage a sequence with start condition, address
and data to transfer without a final stop condition
(++) I2C_FIRST_AND_NEXT_FRAME: Sequential usage (Master only), this option allow to manage a sequence with start condition, address
and data to transfer without a final stop condition, an then permit a call the same master sequential interface
several times (like @ref HAL_I2C_Master_Seq_Transmit_IT() then @ref HAL_I2C_Master_Seq_Transmit_IT()
or @ref HAL_I2C_Master_Seq_Transmit_DMA() then @ref HAL_I2C_Master_Seq_Transmit_DMA())
(++) I2C_NEXT_FRAME: Sequential usage, this option allow to manage a sequence with a restart condition, address
and with new data to transfer if the direction change or manage only the new data to transfer
if no direction change and without a final stop condition in both cases
(++) I2C_LAST_FRAME: Sequential usage, this option allow to manage a sequance with a restart condition, address
and with new data to transfer if the direction change or manage only the new data to transfer
if no direction change and with a final stop condition in both cases
(++) I2C_LAST_FRAME_NO_STOP: Sequential usage (Master only), this option allow to manage a restart condition after several call of the same master sequential
interface several times (link with option I2C_FIRST_AND_NEXT_FRAME).
Usage can, transfer several bytes one by one using HAL_I2C_Master_Seq_Transmit_IT(option I2C_FIRST_AND_NEXT_FRAME then I2C_NEXT_FRAME)
or HAL_I2C_Master_Seq_Receive_IT(option I2C_FIRST_AND_NEXT_FRAME then I2C_NEXT_FRAME)
or HAL_I2C_Master_Seq_Transmit_DMA(option I2C_FIRST_AND_NEXT_FRAME then I2C_NEXT_FRAME)
or HAL_I2C_Master_Seq_Receive_

温馨提示
1、嵌入式物联网单片机项目开发实战。例程经过精心编写,简单好用。 2、代码使用KEIL HAL库开发,当前在STM32F103运行,如果是STM32F103其他型号芯片,依然适用,请自行更改KEIL芯片型号以及FLASH容量即可。 3、软件下载时,请注意keil选择项是jlink还是stlink。 4、技术v:349014857; 5、如果接入其他传感器,请查看发布的其他资料。 6、单片机与模块的接线,在代码当中均有定义,请自行对照。 7、若硬件差异,请根据自身情况适当调整代码,程序仅供参考。 8、代码有注释说明,请耐心阅读。
