|
||||
===============
|
||||
|
||||
|
||||
This is an Arduino software I2C Library, you can use the other pin as I2C interface, such D2, D3.
|
||||
|
||||
But, you should know that this library can only act as Master.
|
||||
|
||||
And, Wire.available() is not correctly supported.
|
||||
|
||||
This library include:
|
||||
|
||||
|
||||
void begin(int Sda, int Scl); // setup
|
||||
uchar beginTransmission(uchar addr); // start
|
||||
uchar endTransmission(); // end
|
||||
uchar available(); // bytes available for reading
|
||||
|
||||
uchar write(uchar dta); // write a byte
|
||||
uchar write(uchar len, uchar *dta); // write a array
|
||||
uchar requestFrom(uchar addr, uchar len); // request some data
|
||||
uchar read(); // read a byte
|
||||
|
||||
|
||||
|
||||
begin() is something different from <Wire.h>, you have to set pin here.
|
||||
beginTransmission() return the uchar, original not.
|
||||
available() return the length set by requestFrom().
|
||||
|
||||
The others function is just like the hard I2C library.
