HELLO,

I built a unit to watch wild pigs.
They come in the night and the unit falls to ground. The programm looks to the watch (DS1302) and notice the time and date to RAM of AT89S52. There are 8 places (time 1..8). The time and date I can see later on LCD (16x2). The unit is battery driven and the battery lives 3 days. I want to use POWER DOWN but I am not able to do this.
All parts of main-programm works fine. The groundfall-switch works to P3.2 and the other switch (place 1to8) works with P3.3 (INT1). AT82S52 RAM places I can see with V24 on PC, this is commode for write the assembler-programm (programmed with ISP).
Who can help me how to install POWER DOWN.

with regards
Manfred POMUTZ
