DS3231M
v1.0.6
Arduino library to use the Maxim Integrated DS3231M RTC (Real-Time-Clock)
|
Class definition header for the DS3231M real-time-clock from Maxim integrated, described at https://www.maximintegrated.com/en/products/digital/real-time-clocks/DS3231M.html. The DS3231M's data sheet is located at https://datasheets.maximintegrated.com/en/ds/DS3231M.pdf
The most recent version of this library can be found at https://github.com/Zanduino/DS3231M and a detailed library description is on the library's wiki at https://github.com/Zanduino/DS3231M/wiki
Use is made of portions of Adafruit's RTClib Version 1.2.0 at https://github.com/adafruit/RTClib which is a fork of the original RTClib from Jeelabs. The code encompasses simple classes for time and date.
Part of the GitHub actions for CI is running every source file through "clang-format" to ensure that coding formatting is done the same for all files. The configuration file ".clang-format" is located at https://github.com/Zanduino/Common/tree/main/clang-format and this is used for CI tests when pushing to GitHub. The local file, if present in the root directory, is ignored when committing and uploading.
