Arduino 2.0.1 and newer support slave and master mode. The two modes have a begin() method with different signature: ``` // Slave Begin bool TwoWire::begin(uint8_t addr, int sdaPin, int sclPin, uint32_t frequency) // Master Begin bool TwoWire::begin(int sdaPin, int sclPin, uint32_t frequency) ``` Use type casting to make sure that overloaded method for master mode is used.
