Here's my third recent PIC project. The stuff on the left is the serial port PIC programmer. The parts on the right are my attempt to interface with a Real Time Chip, DS12887 using a PIC16F84. The first stage was to check if the internal battery still works (the RTC is ~ 20 years old) by reading one of the control registers. The red LED at the right is on, indicating the battery level is good. Success!
