| 17 | ##### How to use this driver #####
|
---|
| 18 | ==============================================================================
|
---|
| 19 | [..]
|
---|
| 20 | The FMPI2C HAL driver can be used as follows:
|
---|
| 21 |
|
---|
| 22 | (#) Declare a FMPI2C_HandleTypeDef handle structure, for example:
|
---|
| 23 | FMPI2C_HandleTypeDef hfmpi2c;
|
---|
| 24 |
|
---|
| 25 | (#)Initialize the FMPI2C low level resources by implement the HAL_FMPI2C_MspInit ()API:
|
---|
| 26 | (##) Enable the FMPI2Cx interface clock
|
---|
| 27 | (##) FMPI2C pins configuration
|
---|
| 28 | (+++) Enable the clock for the FMPI2C GPIOs
|
---|
| 29 | (+++) Configure FMPI2C pins as alternate function open-drain
|
---|
| 30 | (##) NVIC configuration if you need to use interrupt process
|
---|
| 31 | (+++) Configure the FMPI2Cx interrupt priority
|
---|
| 32 | (+++) Enable the NVIC FMPI2C IRQ Channel
|
---|
| 33 | (##) DMA Configuration if you need to use DMA process
|
---|
| 34 | (+++) Declare a DMA_HandleTypeDef handle structure for the transmit or receive stream
|
---|
| 35 | (+++) Enable the DMAx interface clock using
|
---|
| 36 | (+++) Configure the DMA handle parameters
|
---|
| 37 | (+++) Configure the DMA Tx or Rx Stream
|
---|
| 38 | (+++) Associate the initilalized DMA handle to the hfmpi2c DMA Tx or Rx handle
|
---|
| 39 | (+++) Configure the priority and enable the NVIC for the transfer complete interrupt on the DMA Tx or Rx Stream
|
---|
| 40 |
|
---|
| 41 | (#) Configure the Communication Clock Timing, Own Address1, Master Adressing Mode, Dual Addressing mode,
|
---|
| 42 | Own Address2, Own Address2 Mask, General call and Nostretch mode in the hfmpi2c Init structure.
|
---|
| 43 |
|
---|
| 44 | (#) Initialize the FMPI2C registers by calling the HAL_FMPI2C_Init() API:
|
---|
| 45 | (+++) These API's configures also the low level Hardware GPIO, CLOCK, CORTEX...etc)
|
---|
| 46 | by calling the customed HAL_FMPI2C_MspInit(&hfmpi2c) API.
|
---|
| 47 |
|
---|
| 48 | (#) To check if target device is ready for communication, use the function HAL_FMPI2C_IsDeviceReady()
|
---|
| 49 |
|
---|
| 50 | (#) For FMPI2C IO and IO MEM operations, three mode of operations are available within this driver :
