I have one of these and trying to figure out how to use it.
I have the DS1302 library from here: http://playground.arduino.cc//Main/InterfacingWithHardware#InputTOC.
And an example that just sets the time on the chip and then reads it and outputs it in the serial monitor window.
The library seems to successfully read the time from the chip but it doesn’t set it successfully. It seems to be set at some default value from the time of manufacture perhaps.
Has this problem been encountered previously and covered? If so what is the solution?
