The build relies on that old stalwart, the Arduino Uno, to run the show. It’s hooked up to a DS3231 real-time clock module so it can keep accurate time for long periods, as is befitting a clock.

NetTimeLogic’s RTC Master Clock is a full hardware (FPGA) only implementation of a synchronization core allowing to read and write a I2C Realtime Clock (RTC) like the DS1307 or MCP7941x. Access to the ...

The Real Time Clock (RTC) SGC22300 uses the leading oscillator solution SGC21510. This specially designed RTC core uses advanced analog design techniques to guarantee ultra low power consumption ...

A Real Time Clock (RTC) is a digital clock integrated circuit (IC) designed to keep accurate track of time even when the main power supply is turned off or the device is in low power mode. RTCs are ...

We'll look at these protocols in the context of two specific devices, the DS18B20 12-bit temperature sensor and the DS1302 real time clock, but we'll see SPI again in later chapters. (By the way, ...
