I can't believe that it has been exactly one year since I last posted on my 10000 Year Clock.

Well I finally got the low power LCD and put together a prototype of the clock. So progress is being made.

The LCD is a 40-pin 4-digit module 40LCD from Futurlec.

The LCD driver is MAXIM ICL7211A.
Here is the datasheet in pdf.

I have programmed...

I was postponing this post until I got a chance to acquire and test a 2x20 3V LCD.

I have not gotten one as yet so the test will have to wait.

I wanted the display to show the date and time like this:

However, when Wednesday comes around, I need 18 characters across, hence the need for a 2x20 display.

The Calendar

The tricky part with all...

Here is a 24-hr Clock/Calendar project with a twist.

The idea is to create a perpetual clock that will run for 10,000 years without requiring calibration. This idea was inspired by the 10,000 Year Clock project from the Long Now Foundation:

To achieve this goal, I will present the project in stages:

Stage 1 - Simple 24-hr clock program.
Stage 2 - Add date calendar with automatic leap year correction.

You can use your handheld TV remote controller to turn on/off lights, appliances, gadgets, robots, etc.

Here I will show you how you can receive and decode the infra-red (IR) signals transmitted by the controller. This is also an excellent exercise to learn and use the intricate functions of the timer module on the MSP430G2553 microcontroller (mcu).

Be forewarned that this exercise is not for the faint of heart and requires multiple in-depth reading of manufacturers' datasheets...

Here is my MSP430G2553 LCD Terminal program.
Where would I use something like this?

1) If I am debugging a system and would like to see some internal results I can send ASCII text to a dumb terminal. Can I not use the IDE debugger to trace the code? Many times I am debugging in "real time" and am not allowed to stop the code with a break point.

Thus I only need my code to spit out text via a single UART TXD pin on the fly.

2) With low pin count...
