SoftWire

Introduction

SoftWire is a software I2C implementation for Arduino and other Wiring-type environments. It utilises the pinMode(), digitalWrite() and digitalRead() functions. The pins to be used for the serial data (SDA) and serial clock (SCL) control lines can be defined at run-time. Alternatively it is possible to override the functions which control the SDA and SCL lines, and read SDA and SCL, thereby allowing direct port manipulation to be used if preferred.

Multiple objects (for multiple software I2C buses) and clock-stretching by slave devices are supported. A timeout feature is included to prevent lockups by faulty or missing hardware. The microcontroller must function as the master device and multiple masters are not supported.

Low-level functions can be used to send start, and stop signals, and to read and write data; no buffers are required. In addition high-level functions provide almost direct compatibility with the Wire library. However, the user must first declare transmit and receive buffers, and configure SoftWire to use them before the high-level functions beginTransmission(), endTransmission(), read(), write() and requestFrom () can be used. Notify SoftWire of the buffers by calling the setTxBuffer() and setRxBuffer() functions, passing in a pointer to a byte or character buffer and the size of the buffer. See the ReadDS1307 fort an exmaple of how this is done.

It is possible to assign (and reassign) the pins associated with SCL and SDA at run-time using the functions setScl() and setSda().

Important changes for users of the v1.* library

To support the high-level functions required for compatibility with the Wire library the original low-level write() function has been renamed llWrite().

The setter functions setSdaLow(), setSdaHigh(), setSclLow(), setSclHigh(), setReadSda(), setReadScl() must be used to override the functions which control and read the SDA and SCL signals.

The functions which actually set SCL/SDA low/high are now named sclLow(), sdaLow(), sclHigh() and sdaHigh(). These functions should not be called directly in normal use but may be required to force some devices into low-power mode.

SoftWire
Introduction
SoftWire is a software I2C implementation for Arduino and other
Wiring-type environments. It utilises the pinMode(),
digitalWrite() and digitalRead() functions. The pins to be used
for the serial data (SDA) and serial clock (SCL) control lines can be
defined at run-time. Alternatively it is possible to override the
functions which control the SDA and SCL lines, and read SDA and SCL,
thereby allowing direct port manipulation to be used if preferred.
Multiple objects (for multiple software I2C buses) and
clock-stretching by slave devices are supported. A timeout feature is
included to prevent lockups by faulty or missing hardware. The
microcontroller must function as the master device and multiple
masters are not supported.
Low-level functions can be used to send start, and stop signals, and
to read and write data; no buffers are required. In addition
high-level functions provide almost direct compatibility with the Wire
library. However, the user must first declare transmit and receive
buffers, and configure SoftWire to use them before the high-level
functions beginTransmission(), endTransmission(), read(), write() and
requestFrom () can be used. Notify SoftWire of the buffers by calling the
setTxBuffer() and setRxBuffer() functions, passing in a pointer to a
byte or character buffer and the size of the buffer. See the ReadDS1307 fort an exmaple of how this is done.
It is possible to assign (and reassign) the pins associated with SCL and SDA
at run-time using the functions setScl() and setSda().
Important changes for users of the v1.* library
To support the high-level functions required for compatibility with
the Wire library the original low-level write() function has been
renamed llWrite().
The setter functions setSdaLow(), setSdaHigh(), setSclLow(),
setSclHigh(), setReadSda(), setReadScl() must be used to
override the functions which control and read the SDA and SCL signals.
The functions which actually set SCL/SDA low/high are now named
sclLow(), sdaLow(), sclHigh() and sdaHigh(). These functions
should not be called directly in normal use but may be required to
force some devices into low-power mode.
