| The ATMega32 chip in the M32 has a
real-time counter that operates asynchronously when a 32khz watch
crystal is connected to it, providing a real-time clock.
Bascom has built-in support for the RTC, making it very easy to use
time functions. You can purchase the parts needed as a kit by clicking
here.
 First
let's install the watch crystal. The watch crystal needs to
connect to pins TOSC1(28) and TOSC2(29). To do this, we need
to solder the watch crystal to a couple of female crimp connectors.
Use something to hold the crimp connectors while you are soldering,
small parts can be difficult to solder. Be sure to crimp the pins
before soldering so they will fit into a plastic housing.
You could also solder the crystal directly to
the male posts, but I would recommend using the crimp connectors.
 Next,
slide the female crimp connectors into a 2-pin plastic housing. Now
you can install and remove the watch crystal as needed.
 Slide
the connector onto pins 28 & 29 as shown in the picture.
 Now
fold the crystal down against the plastic housing as shown. This will
keep the crystal safe. You could use a drop of hot glue to secure the
crystal in place and protect it. Click the picture to see a close up.
