5x7 Led Dot Matrix Clock using only one chip



I use a microcontroller, pic16f887, as the brain of this clock. The time displays on a small 5x7 led dot matrix in lanscape mode. The chip is running with the internal oscillator at 4.0 MHz. External frequency 32.768KHz for time base is getting from DS32KHz. The accuracy is not that impressive, ~2 sec/day.
The schematic and source code in MikroC will be posted here. Please stay tuned!!
--- Update --
Source Code is now available at 5x7 dot matrix clock code
Schematic is available at 5x7 Dot Matrix clock schematic
