| Revision | Date | Who | Commit message |
|---|---|---|---|
| 4:dc3e19dfd45d | 2016-05-15 | oliverb | Improved byte cache, now needs only one SPI data write for a hit. |
| 3:0a38cff87d2e | 2016-05-09 | oliverb | Moved the bit reverse LUT out |
| 2:ecf13e85f0fa | 2016-05-08 | oliverb | Caching of address and location of last byte written makes it crazy-fast for vertical-aligned drawing operations; After a pixel write any further pixel writes that land in the same display byte need only one SPI write operation to complete. |
| 1:09dc95ba8711 | 2016-05-08 | oliverb | First working version, enables use of three intensity values instead of pixel on/off |
| 0:e760d4cfabe4 | 2016-05-07 | oliverb | Converted to Library, moved the examples out |
