A whole lot of rewriting and changes has happened since the last post. It's far from complete, but what's there is fairly useable, I think. I'm a whole lot happier with this code than the last iteration. But that could change quickly. We shall see...
I cut i2c timings down from 20uS to 10uS, and t...
After getting my clock code to the stage it was at in Part 2, I started to refine the code and add features. That code was pretty quick and dirty. It worked, but still needed lots of work.
I started looking at actual i2c timings. I had built my clock code by just picking a random number (100uS) th...
After not looking at electronics for quite a while, and PICs for even longer, I started a project with the PIC16F72 board and soon found out why those savage old chips were being sold from China for cheap. I ran out of memory right quick. Could have probably done it if I switched to assembly langu...
On a recent China order I bought five 16F72 PIC microcontrollers in 16-SOIC for very cheap, thinking I could find some use for them. They sat in a box for a long time. Lately I've finally got somewhat caught up with work and have a little time for electronics tinkering again, so I decided to wire on...
I got my PC boards from OSH Park. The top boards are just some SOT23 breakouts to make breadboarding easier. Soldering wire legs onto SOT23s is a little difficult, and they don't hold up well to plugging and unplugging.
The bottom boards are my PIC10F322 general purpose board. OSH Park shorted me...
