Member Function Documentation

template<uint8_t sclPin, uint8_t sdaPin>

void FastI2cMaster< sclPin, sdaPin >::begin ( )

inline

Initialize I2C bus pins.

Definition at line 174 of file SoftI2cMaster.h.

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]

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.

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.
