Work in Progress - Winbond-based text editor

Mike Green

This is the Winbond flash driver posted earlier and the FemtoBasic variant used with that. There's a text editor (Ouroboros) included that's far enough along so you can edit a 39 line x 80 character display buffer and save (and re-edit) the files. From the text editor, you can run a named program on the flash drive (like FemtoBasic). I plan to continue debugging and improving the text editor, then start on some kind of simple compiler, maybe for a Basic similar to PBasic.

This current program runs on a Demo Board with a Winbond W25X16A SPI 2MB flash memory and two Microchip 23K256 SPI 32K SRAMs installed on the breadboard area. The flash memory is used for file storage and the SRAMs are used for buffers and work areas. The editor uses them to store the text being edited and the compiler will use them for its dictionary and other tables.

Nice work Mike!

Very impressive, Mike. I see you've even put some kind of wear levelling in there (!)

Look forward to trying it (got to hook up a winbond first)
