[SOLVED] I2C requestFrom() - how to read > 32 bytes?

Firmware Libraries

@RWB, yes, I ported it okay, but have not turned into a library (I must learn how to do that one day)!

You just need to make these changes:

// HR's port
#define i2c_scl_release()                           \
                    pinMode(_sclPin, INPUT);
#define i2c_sda_release()                           \
                    pinMode(_sdaPin, INPUT);

// sets SCL low and drives output
#define i2c_scl_lo()                                \
                    pinResetFast(_sclPin);          \
                    pinMode(_sclPin, OUTPUT);  



// sets SDA low and drives output
#define i2c_sda_lo()                                \
                    pinResetFast(_sdaPin);          \
                    pinMode(_sdaPin, OUTPUT);  

// Setting SCL high and to input releases pin ie floating
// HR NOTE - not implementing PULLUP as is pulled up externally
#define i2c_scl_hi()                                \
                    pinSetFast(_sclPin);            \
                    pinMode(_sclPin, INPUT);  


// Setting SDA high and to input releases pin ie floating
// HR NOTE - not implementing PULLUP as is pulled up externally
#define i2c_sda_hi()                                \
                    pinSetFast(_sdaPin);            \
                    pinMode(_sdaPin, INPUT);

Also follow these comments:

2016-09-19 
- Removed i2c_init() from being called in SoftI2CMaster() constructor(s)
- Renamed i2c_init() to begin()

Hope this helps.
