Member Function Documentation

◆ begin()

template<uint8_t sclPin, uint8_t sdaPin>
void FastI2cMaster< sclPin, sdaPin >::begin ( )
inline

Initialize I2C bus pins.

Definition at line 186 of file SoftI2cMaster.h.

◆ read()

template<uint8_t sclPin, uint8_t sdaPin>
uint8_t FastI2cMaster< sclPin, sdaPin >::read ( uint8_t  last)
inlinevirtual

Read a byte

Note
This function should only be used by experts. Data should be accessed by calling transfer() and transferContinue()
Parameters
[in]lastsend a NACK to terminate read if last is true else send an ACK to continue the read.
Returns
byte read from I2C bus

Implements I2cMasterBase.

◆ start()

template<uint8_t sclPin, uint8_t sdaPin>
void FastI2cMaster< sclPin, sdaPin >::start ( )
inlinevirtual

Issue a start condition

Note
This function should only be used by experts. Data should be accessed by calling transfer() and transferContinue()

Implements I2cMasterBase.

◆ stop()

template<uint8_t sclPin, uint8_t sdaPin>
void FastI2cMaster< sclPin, sdaPin >::stop ( void  )
inlinevirtual

Issue a stop condition.

Note
This function should only be used by experts. Data should be accessed by calling transfer() and transferContinue()

Implements I2cMasterBase.

Definition at line 234 of file SoftI2cMaster.h.

◆ write()

template<uint8_t sclPin, uint8_t sdaPin>
bool FastI2cMaster< sclPin, sdaPin >::write ( uint8_t  data)
inlinevirtual

Note
This function should only be used by experts. Data should be accessed by calling transfer() and transferContinue()
Parameters
[in]databyte to write
Returns
true for ACK or false for NACK

Implements I2cMasterBase.
