So the first thing to enable a RTC is to set up I2C. Setting-up I2CĪny RTC uses the I2C protocol to communicate with the Raspberry Pi. There are various inexpensive add-on RTC boards available that simply plug on top of the Raspberry Pi’s GPIO pins. Why Most of the applications or websites. STs parallel real-time clock ICs, also called Timekeepers, combine a SRAM with up to 256 Kbytes of memory and a byte-wide interface along with a quartz-based. My main goal was to build a website where you can find real exact time. This can be a problem for stand-alone projects with no network connection, as your Raspberry Pi will not be able to accurately keep the time. Welcome, let me introduce the clock.zone. Instead, the Raspberry Pi updates the time automatically from the global ntp (nework time protocol) servers. Table of contentsīecause the Raspberry Pi is designed as an ultra-low cost computer, it lacks the little coin-battery-powered ‘Real Time Clock’ (RTC) module that sits in your laptop or desktop computer. In this guide I explain how to add a real-time clock. The Raspberry Pi keeps track of time by checking the internet, which becomes problematic when no internet connection is available. Este es un reloj grande que muestra la hora en pantalla completa. Displays your local time, or the time in most any location around the world. Add a real-time clock to your Raspberry Pi
