Wire library

This library allows you to communicate with I2C / TWI devices via the SDA (data line) and SCL (clock line) pins.

Functions

• begin()
• requestFrom()
• beginTransmission()
• endTransmission()
• write()
• available()
• read()
• onReceive()
• onRequest()

注意

There are both 7- and 8-bit versions of I2C addresses. 7 bits identify the device, and the eighth bit determines if it’s being written to or read from. The Wire library uses 7 bit addresses throughout. If you have a datasheet or sample code that uses 8 bit address, you’ll want to drop the low bit (i.e. shift the value one bit to the right), yielding an address between 0 and 127.
