README
readme.mdOWO PIC Demo Board
This is a very simple demo board I designed around one of my favorite microcontrollers: The PIC 16F628A from Microchip. I also wrote a small "framework" in asm for it, that handles the display, buttons, serial comm, text scrolling, etc, and I've included a simple implementation of Tetris as an example of its usage.
You'll find the schematic and board layout (KiCad) of the OWO board in the /board folder. There's a lot that can be improved but it works as it is. The demo code and framework/boilerplate is in the /asm_demo_code directory.
You can see a video of one the early builds of the Tetris demo running on the board:

Questions
How big is the Owo demo board PCB?
It measures 80.5 × 93.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Owo demo board use?
37 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Owo demo board KiCad files?
From the battlecoder/owo_pic_demo_board repository on GitHub, at the commit this page was made from: the board is board/owo_demo_board.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Owo demo board design in my own project?
Its repository states no licence, so its author keeps all rights: ask battlecoder before reusing the design.
