Description : Conditional Compilation -- Make program run the same on any
BS2-famil BASIC Stamp
BE AWARE: The original post was using a
button cell with a DS1302 real time clock.
If you use a button cell, you DO NOT want
to turn on trickle charge -- I think this
will destroy the battery, or cause it to
explode.
The default, out of the box behavior of the
DS1302 is when VBATT is higher than VCC, then
VBATT drives the clock. The 'trickle charge'
circuitry is designed for NiCad, or SuperCap,
neither of which applies when using
button cells.
A little nuance, that may get missed by the general public, which the author
added. There is a pull down resistor on the gate of the fet. This is good.
This ensures that the fet will be pulled down, off, in case something goes
wrong. For example, the power to the load is on, but the power to the stamp
is off for some reason<G>.
