Datasheet

To write to one (or more) registers, issue a write command and transmit the register

address that should be written to, followed by the data byte to be written. Issuing another

write command will automatically write the value in the next register. This can go on until

all registers have been written to. After writing to the last register, additional write

commands will do nothing.

Writing register values

All registers can be read, but only registers marked

read/write can be written to.

Example

Start writing at address 0x05 and write 2 values.

byte i2c_device_address=0x64;

byte starting_register=0x05

byte data=1;

Wire.beginTransmission(i2c_device_address);

Wire.write(starting_register);

Wire.write(data);

Wire.endTransmission();
