A real-time clock (RTC) is an electronic device (most often in the form of an integrated circuit) that measures the passage of time. Although the term often refers to the devices in personal computers, servers and embedded systems, RTCs are present in almost any electronic device which needs to keep accurate time of day. clark howard on credit unionsWebThe next step is to connect the Blue Pill to the ST-Link V2 (figure 5). Just connect the corresponding pins on the ST-LinkV2 clone to the STM32duino. Note that there are two GND’s and two 3V3’s on the ST-Link V2. Any one of them will do for the 3V3 and GND. Also move the STM32duino jumpers to the “1” position as shown. clark howard on extended car warranty

"WebMost RTC modules, such as the DS1307, require an external 32kHz crystal oscillator for timekeeping. The issue with these crystals is that their oscillation frequency is affected by external temperature. This change in frequency is negligible, but it adds up. " - Rtc crystal difference
