Basic state monitoring (Using I2C_CheckEvent() function) - ----------------------------------------------------------- - It compares the status registers (SR1 and SR2) 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 ST_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 (RM0090). - - 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). - - I2Cx_ER_IRQHandler() which is called when the error interrupt occurs. - Where x is the peripheral instance (I2C1, I2C2 ...) - - I2C_GetFlagStatus() or I2C_GetITStatus() to be called into the - I2Cx_ER_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()) - -------------------------------------------------------------------- - Using the function I2C_GetLastEvent() which returns the image of both status - registers in a single word (uint32_t) (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 - allows to overcome the mentioned limitation of I2C_GetFlagStatus() - function. - - The returned value could be compared to events already defined in - the library (stm32f4xx_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()) - ----------------------------------------------------------------------- - - 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 - stm32f4xx_i2c.h file. - -@endverbatim - * @{ - */ - -/** - * @brief Reads the specified I2C register and returns its value. - * @param I2C_Register: specifies the register to read. - * This parameter can be one of the following values: - * @arg I2C_Register_CR1: CR1 register. - * @arg I2C_Register_CR2: CR2 register. - * @arg I2C_Register_OAR1: OAR1 register. - * @arg I2C_Register_OAR2: OAR2 register. - * @arg I2C_Register_DR: DR register. - * @arg I2C_Register_SR1: SR1 register. - * @arg I2C_Register_SR2: SR2 register. - * @arg I2C_Register_CCR: CCR register. - * @arg I2C_Register_TRISE: TRISE register. - * @retval The value of the read register. - */ -uint16_t I2C_ReadRegister(I2C_TypeDef* I2Cx, uint8_t I2C_Register) -{ - __IO uint32_t tmp = 0; - - /* Check the parameters */ - assert_param(IS_I2C_ALL_PERIPH(I2Cx)); - assert_param(IS_I2C_REGISTER(I2C_Register)); - - tmp = (uint32_t) I2Cx; - tmp += I2C_Register; - - /* Return the selected register value */ - return (*(__IO uint16_t *) tmp); -} - -/** - * @brief Enables or disables the specified I2C interrupts. - * @param I2Cx: where x can be 1, 2 or 3 to select the I2C peripheral. - * @param I2C_IT: specifies the I2C interrupts sources to be enabled or disabled. - * This parameter can be any combination of the following values: - * @arg I2C_IT_BUF: Buffer interrupt mask - * @arg I2C_IT_EVT: Event interrupt mask - * @arg I2C_IT_ERR: Error interrupt mask - * @param NewState: new state of the specified I2C interrupts. - * This parameter can be: ENABLE or DISABLE. - * @retval None - */ -void I2C_ITConfig(I2C_TypeDef* I2Cx, uint16_t I2C_IT, FunctionalState NewState) -{ - /* Check the parameters */ - assert_param(IS_I2C_ALL_PERIPH(I2Cx)); - assert_param(IS_FUNCTIONAL_STATE(NewState)); - assert_param(IS_I2C_CONFIG_IT(I2C_IT)); - - if (NewState != DISABLE) - { - /* Enable the selected I2C interrupts */ - I2Cx->CR2 |= I2C_IT; - } - else - { - /* Disable the selected I2C interrupts */ - I2Cx->CR2 &= (uint16_t)~I2C_IT; - } -} - -/* - =============================================================================== - 1.

Enable peripheral clock using the following functions - * RCC_APB2PeriphClockCmd(RCC_APB2Periph_SPI1, ENABLE) for SPI1 - * RCC_APB1PeriphClockCmd(RCC_APB1Periph_SPI2, ENABLE) for SPI2 - * RCC_APB1PeriphResetCmd(RCC_APB1Periph_SPI3, ENABLE) for SPI3. - * - * 2. Enable SCK, MOSI, MISO and NSS GPIO clocks using RCC_AHB1PeriphClockCmd() - * function. - * In I2S mode, if an external clock source is used then the I2S CKIN pin GPIO - * clock should also be enabled. - * - * 3. Peripherals alternate function: - * - Connect the pin to the desired peripherals' Alternate - * Function (AF) using GPIO_PinAFConfig() function - * - Configure the desired pin in alternate function by: - * GPIO_InitStruct->GPIO_Mode = GPIO_Mode_AF - * - Select the type, pull-up/pull-down and output speed via - * GPIO_PuPd, GPIO_OType and GPIO_Speed members - * - Call GPIO_Init() function - * In I2S mode, if an external clock source is used then the I2S CKIN pin - * should be also configured in Alternate function Push-pull pull-up mode. - * - * 4. Program the Polarity, Phase, First Data, Baud Rate Prescaler, Slave - * Management, Peripheral Mode and CRC Polynomial values using the SPI_Init() - * function. - * In I2S mode, program the Mode, Standard, Data Format, MCLK Output, Audio - * frequency and Polarity using I2S_Init() function. - * For I2S mode, make sure that either: - * - I2S PLL is configured using the functions RCC_I2SCLKConfig(RCC_I2S2CLKSource_PLLI2S), - * RCC_PLLI2SCmd(ENABLE) and RCC_GetFlagStatus(RCC_FLAG_PLLI2SRDY). - * or - * - External clock source is configured using the function - * RCC_I2SCLKConfig(RCC_I2S2CLKSource_Ext) and after setting correctly the define constant - * I2S_EXTERNAL_CLOCK_VAL in the stm32f4xx_conf.h file. - * - * 5. Enable the NVIC and the corresponding interrupt using the function - * SPI_ITConfig() if you need to use interrupt mode. - * - * 6. When using the DMA mode - * - Configure the DMA using DMA_Init() function - * - Active the needed channel Request using SPI_I2S_DMACmd() function - * - * 7. Enable the SPI using the SPI_Cmd() function or enable the I2S using - * I2S_Cmd(). - * - * 8. Enable the DMA using the DMA_Cmd() function when using DMA mode. - * - * 9. Optionally, you can enable/configure the following parameters without - * re-initialization (i.e there is no need to call again SPI_Init() function): - * - When bidirectional mode (SPI_Direction_1Line_Rx or SPI_Direction_1Line_Tx) - * is programmed as Data direction parameter using the SPI_Init() function - * it can be possible to switch between SPI_Direction_Tx or SPI_Direction_Rx - * using the SPI_BiDirectionalLineConfig() function. - * - When SPI_NSS_Soft is selected as Slave Select Management parameter - * using the SPI_Init() function it can be possible to manage the - * NSS internal signal using the SPI_NSSInternalSoftwareConfig() function. - * - Reconfigure the data size using the SPI_DataSizeConfig() function - * - Enable or disable the SS output using the SPI_SSOutputCmd() function - * - * 10. To use the CRC Hardware calculation feature refer to the Peripheral - * CRC hardware Calculation subsection. - * - * - * It is possible to use SPI in I2S full duplex mode, in this case, each SPI - * peripheral is able to manage sending and receiving data simultaneously - * using two data lines. Each SPI peripheral has an extended block called I2Sxext - * (ie. I2S2ext for SPI2 and I2S3ext for SPI3). - * The extension block is not a full SPI IP, it is used only as I2S slave to - * implement full duplex mode. The extension block uses the same clock sources - * as its master. - * To configure I2S full duplex you have to: - * - * 1. Configure SPIx in I2S mode (I2S_Init() function) as described above. - * - * 2. Call the I2S_FullDuplexConfig() function using the same strucutre passed to - * I2S_Init() function. - * - * 3. Call I2S_Cmd() for SPIx then for its extended block. - * - * 4. To configure interrupts or DMA requests and to get/clear flag status, - * use I2Sxext instance for the extension block. - * - * Functions that can be called with I2Sxext instances are: - * I2S_Cmd(), I2S_FullDuplexConfig(), SPI_I2S_ReceiveData(), SPI_I2S_SendData(), - * SPI_I2S_DMACmd(), SPI_I2S_ITConfig(), SPI_I2S_GetFlagStatus(), SPI_I2S_ClearFlag(), - * SPI_I2S_GetITStatus() and SPI_I2S_ClearITPendingBit(). - * - * Example: To use SPI3 in Full duplex mode (SPI3 is Master Tx, I2S3ext is Slave Rx): - * - * RCC_APB1PeriphClockCmd(RCC_APB1Periph_SPI3, ENABLE); - * I2S_StructInit(&I2SInitStruct); - * I2SInitStruct.Mode = I2S_Mode_MasterTx; - * I2S_Init(SPI3, &I2SInitStruct); - * I2S_FullDuplexConfig(SPI3ext, &I2SInitStruct) - * I2S_Cmd(SPI3, ENABLE); - * I2S_Cmd(SPI3ext, ENABLE); - * ... - * while (SPI_I2S_GetFlagStatus(SPI2, SPI_FLAG_TXE) == RESET) - * {} - * SPI_I2S_SendData(SPI3, txdata[i]); - * ... - * while (SPI_I2S_GetFlagStatus(I2S3ext, SPI_FLAG_RXNE) == RESET) - * {} - * rxdata[i] = SPI_I2S_ReceiveData(I2S3ext); - * ... - * - * - * @note In I2S mode: if an external clock is used as source clock for the I2S, - * then the define I2S_EXTERNAL_CLOCK_VAL in file stm32f4xx_conf.h should - * be enabled and set to the value of the source clock frequency (in Hz). - * - * @note In SPI mode: To use the SPI TI mode, call the function SPI_TIModeCmd() - * just after calling the function SPI_Init(). - * - * @endverbatim - * - ****************************************************************************** - * @attention - * - * THE PRESENT FIRMWARE WHICH IS FOR GUIDANCE ONLY AIMS AT PROVIDING CUSTOMERS - * WITH CODING INFORMATION REGARDING THEIR PRODUCTS IN ORDER FOR THEM TO SAVE - * TIME.
