I have found that the use of the RTC chip- DS3231 is extremely hard using the arduino. Just setting the time is pretty complex, not mentioning the code. Therefore I have found a great and easy to use library which really enhances the use of the DS3231 chip. Let's get right onto it...
An Arduino library for the DS3231 real-time clock (RTC). Description The library provides easy-to-use methods to: set and read the current date and time; set, clear, and detect two, independent, Time-of-Day alarms; perform certain conversions and calculations with time data; ...
初始化后RTCDS3231不循环。 、、 我正在尝试使用RTCDS3231--但它在void setup()中初始化后不会循环。到目前为止,我只尝试了示例代码:DS3231: Real-Time Clock.http://www.jarzebski.pl*/ #include <DS3231.h> RTCDateTime dt; { S 浏览21提问于2021-12-11得票数0 ...
The Arduino is in turn connected to the Precision RTC DS3231 module via the I²C-interface: A4 (SDA), A5 (SCL) pins (SDA - data line and SCL - clock line). The interrupt on the port D2 (or D3) serves to count milliseconds by the internal Arduino counter millis. The suggested ...
mcu_clock_drift:Demonstrates that MCU time as kept by theTimelibrary will drift as compared to RTC time, and that MCU time may not increase by one second every second. tiny3232_KnockBang:Demonstrates interfacing an ATtiny45/85 to a DS3231 or DS3232 RTC. ...
