This is a library to handle Seiko's RX8010SJ RTC module with an arduino. Original datasheet can be found here. To set up your module, you only need to power up and use the i2c protocol to communicate ...

DS1307 modules are readily available, and often the cheapest RTC solution available at most outlets. The DS3234 has the distinction of using an SPI interface instead of I2C. It also packs in 256 ...

Macetech’s ChronoDot is a Real Time Clock module for projects requiring highly ... For the ChronoDo(h/t), sample Arduino code and schematics are provided on Macetech’s website, making initial ...

The RTC module is set to the correct time using the DCF77 receiver ... The software should also works with the pin-compatible AVR controllers ATmega8, ATmega88 and ATmega328 (e.g. Arduino nano, uno, ...

Since we're not planning to use the RTC module, we never enable it in the PRCM. Could the fact that we're not enabling the RTC module in the PRCM have an impact on the behavior of the RTC_PMIC_EN pin ...

As you may recall, for this revision of our hardware we connected the HIB output pin to the 3.3V enable so the hibernation module controls the 3.3V rail. Here is what we have learned about the issue ...
