Watch

I have to send my watch off every four or five years and am then left with no watch for a while. In the spirit of other making, I've decided to have a go at a watch of my own.

This is a breadboarded circuit using the 40 pin DIP chip. I bought a few of the DIP versions as they are much better for prototyping, I don't want to have to build a PCB at this stage.

The OLED display is here, I have written some simple I2C functions to talk to it and  have just sent an initialisation sequence. It's quite a complicated driver and so requires a lot of initialisation just to get to this point. The display pattern is just random RAM data, with some other data written on top.
