Re: TI-H: DRAM Expander
I'm probably going to design a basic compatible model. Most likely it will
use an old 4x20 LCD I have laying arround.
My code that I had before was basically very perimitive.
It would use a segment LED to display a file number. The up and down
arrows changed the number, and the right and left either sent or received
files.
