| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Added fix for corner case where badly behaving master doesn't NACK and we don't get the callbacks fires. Removed my own name from several places and added attribution to the correct place.

Also works with multimaster Usage: i2c_msg msg; char buffer[255]; main() { i2c_slave_enable(I2C1, I2C_FAST_MODE | I2C_SLAVE_DUAL_ADDRESS | I2C_SLAVE_GENERAL_CALL | I2C_SLAVE_USE_RX_BUFFER); // init slave mode.
