Witryna25 lip 2013 · This backpack could use I2C, and the address is selectable so it could work comfortably with the RTC. The I2C device is a DS1307 RTC module using SDA/SCL (also D2,D3 on the Leonardo) address 0x68. Multiple I2C devices can be used on an I2C bus provided each device has an unique address. Similarly the Adafruit 'SPI' system …
