AVRs as Dedicated Peripherals

focalist:
AVRs are so cheap now, it makes sense to use them to replace other chips.. Even if it is an underuse of an avr by our standards.

When using 16x2 LCD's, I hate wasting all those pins. Atmega8 costs $1.20, two caps costs a dime, internal oscillator is fine.... And makes an awesome serial and I2C interface chip. For a buck thirty, you can build character sets, handle sprites... Etc..

I am also going to do something similar with a 328 and the TVOUT lib.

All of a sudden, using a "whole" avr doesn't seem like such a waste...

I agree. I was just looking at the ATTiny2313 to make an LCD "backpack". It has a full 8-bit port and a USART and is even smaller than a 328.
