Member Function Documentation

read()

uint8_t SoftI2cMaster::read ( uint8_t  last )

virtual

Read a byte

Note

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

Parameters

[in]

last

send 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()

void SoftI2cMaster::start ( )

virtual

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()

void SoftI2cMaster::stop ( void  )

virtual

Issue a stop condition.

Note

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

Implements I2cMasterBase.

write()

bool SoftI2cMaster::write ( uint8_t  data )

virtual

Write a byte

Note

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

Parameters

[in]

data

byte to write

Returns

true for ACK or false for NACK

Implements I2cMasterBase.
