Detailed Description

Function Documentation

◆ LL_I2C_DisableIT_BUF()

__STATIC_INLINE void LL_I2C_DisableIT_BUF ( I2C_TypeDef *  I2Cx)

Disable Buffer interrupts.

Note
Any of these Buffer events will generate interrupt : Receive buffer not empty (RXNE) Transmit buffer empty (TXE) @rmtoll CR2 ITBUFEN LL_I2C_DisableIT_BUF
Parameters
I2CxI2C Instance.
Return values
None

Definition at line 1151 of file stm32f4xx_ll_i2c.h.

◆ LL_I2C_DisableIT_ERR()

__STATIC_INLINE void LL_I2C_DisableIT_ERR ( I2C_TypeDef *  I2Cx)

Disable Error interrupts.

Note
Macro IS_SMBUS_ALL_INSTANCE(I2Cx) can be used to check whether or not SMBus feature is supported by the I2Cx Instance.
Any of these errors will generate interrupt : Bus Error detection (BERR) Arbitration Loss (ARLO) Acknowledge Failure(AF) Overrun/Underrun (OVR) SMBus Timeout detection (TIMEOUT) SMBus PEC error detection (PECERR) SMBus Alert pin event detection (SMBALERT) @rmtoll CR2 ITERREN LL_I2C_DisableIT_ERR
Parameters
I2CxI2C Instance.
Return values
None

Definition at line 1204 of file stm32f4xx_ll_i2c.h.

◆ LL_I2C_DisableIT_EVT()

__STATIC_INLINE void LL_I2C_DisableIT_EVT ( I2C_TypeDef *  I2Cx)

Disable Events interrupts.

Note
Any of these events will generate interrupt : Start Bit (SB) Address sent, Address matched (ADDR) 10-bit header sent (ADD10) Stop detection (STOPF) Byte transfer finished (BTF) Receive buffer not empty (RXNE) Transmit buffer empty (TXE) @rmtoll CR2 ITEVTEN LL_I2C_DisableIT_EVT
Parameters
I2CxI2C Instance.
Return values
None

Definition at line 1112 of file stm32f4xx_ll_i2c.h.

◆ LL_I2C_EnableIT_BUF()

__STATIC_INLINE void LL_I2C_EnableIT_BUF ( I2C_TypeDef *  I2Cx)

Enable Buffer interrupts.

Note
Any of these Buffer events will generate interrupt if Events interrupts are enabled too(using unitary function LL_I2C_EnableIT_EVT()) : Receive buffer not empty (RXNE) Transmit buffer empty (TXE) @rmtoll CR2 ITBUFEN LL_I2C_EnableIT_BUF
Parameters
