- Improved latching of VDC char base address. Almost there… Artifacts between logo and scroller of VDC101 no longer appear. Still need to fix smooth x scrolling for logo and remove artifacts above logo.
- Fixed a bug with character vertical size. VDC101 logo imageshows correctly in demo linked in next dot point.
- Fixed a bug with VDC register 6. Still not perfect yet but a huge improvement running VDC101
