Detailed Description

Description

This program is used to execute all public functions in the MCP7940 library and check, insofar as possible, whether they functions as expected. This is used during a development cycle to see if any changes or enhancements may have broken previously working functionality.
The MCP7940 library as well as the most current version of this program is available at GitHub using the address https://github.com/Zanduino/MCP7940 and a more detailed description of this program can be found at https://github.com/Zanduino/MCP7940/wiki/RegressionTests.ino

The MCP7940 library uses the standard SPI Wire library for communications with the RTC chip and has also used the class definitions of the standard RTClib library from Adafruit/Jeelabs.

The data sheet for the MCP7940M is located at http://ww1.microchip.com/downloads/en/DeviceDoc/20002292B.pdf. The MCP7940N has extra functionality revolving around battery backup but this library's functionality covers that chip as well.
