Used by the master to request bytes from a slave device. The bytes may then be retrieved with theavailable()andread()functions. As of Arduino 1.0.1, requestFrom() accepts a boolean argument changing its behavior for compatibility with certain I2C devices. If true, requestFrom() sends a stop...

the I²C bus address is 0x63. By default, the "Si4735 Arduino Library" uses the 0x11 I²C bus address (SEN pin connected to GND). If you want to use the address 0x63 (SEN connected on +3.3V), see the functions (methods) getDeviceI2CAddress, setDeviceI2CAddress and setDeviceOt...
If you do need to work with a String class, you need to make an array of characters, as shown here: char name[5] = {'j', 'o', 's', 'h', 0}; or char name[] = "josh"; If you need to, for example, store multiple strings in an array, you can create an array with ...
