Hi! I am new to here. Several months ago I got a Launchpad with two chips 2553 & 2452 inside the box. I am really enjoying it except one thing: They have no LCD driver. Considering an external LCD module will bring terrible power consumption, I wonder if I can drive a simple 3 1/2 digits 7 segments LCD with very little power consumption.
After searching the internet I found Maxim's 4 digits decoder ICM7211 might be a choice, but it is hard to access and so expensive that I cannot accept. Another choice is to use BCD to 7 segments decoder, finally I found 4543 BCD to 7 segments decoder
