Real Time (DS1302) issues

Our DS1302 chip isn't keeping real time. We're using the downloaded code from the part's information page. When we come in to check the time in the morning (8:00 am), the clock always reads 5:30 am. Any suggestions?

    Can't tell without more information like a schematic and layout. These RTCs are very sensitive to physical layout. Sometimes the crystal won't oscillate.

    Hello,

    The AppKit code on that page is somewhat out of date and will be changed soon to point at the link below, which is demo code specifically for the DS1302 and BASIC Stamp 2. I would recommend using the code provided at that link instead. Did you get the crystal from us? I hope this helps. Take care.

    I am so sorry but I just had to do it.
