H A D | ds3231.c | 279399 Sat Feb 28 19:18:04 MST 2015 loos Add a driver for the Maxim DS3231 a low-cost, extremely accurate (+-2PPM) I2C real-time clock (RTC). The DS3231 has an integrated temperature-compensated crystal oscillator (TXCO) and crystal. DS3231 has a temperature sensor, an independent 32kHz output (which can be turned on and off by the driver) and another output that can be used as interrupt for alarms or as a second square-wave output, which frequency and operation mode can be set by driver sysctl(8) knobs.
