ds1307-rtc-write
xod/common-hardware/ds1307-rtc-write
Writes a new date/time value to a DS1307, DS1337, DS1338, or DS3231 real-time clock IC. Useful as a throw-away node to setup the RTC once after you install a backup battery.
Possible errors:
— Invalid I2C address
— Data too long to fit in transmit buffer
— Received NACK on transmit of address
— Received NACK on transmit of data
— Other error
— No bytes written. Probably due to buffer overflow.
