LCD Digital Clock

This clock is pretty similar in terms of effort to my previous seven-seg LED based digital clock -- but the outcome is just not comparable. See for yourself.

The only difference between this from my previous clock, is that the display logic now drives the standard 16x2 alpha numeric LCD instead of multiplexing around those 4 seven segment LEDs (infact I don't have to do multiplexing now, so it is even simpler with only one timer as opposed to the earlier clock with 2 timers). I'm not going to talk about the driver code for the 16x2 alphanumeric LCD for two reasons. First, it is pretty complicated to be put in here and would not really fit the audience. Second, this info is available all around the web, it is just the matter of coding the protocol between the uC and the LCD chip.

Here is the LCD clock in action:
