Michael Hanselmann	6052af94b0	waveshare213v2: Move initialization to testable functions	4 years ago
Michael Hanselmann	5179e40adf	waveshare213v2: Use color for clearing ... This is an API-breaking change, albeit a simple one: Previously the Dev.Clear function received a byte named "color". It was sent directly to the display, thus acting more like a pattern to fill the display with. In practice only 0 and 255 are likely to be used. With this change the function is changed to receive a value of type color.Color which is then converted to image1bit.Bit before filling the display. The latter is also given a unittest.

Michael Hanselmann	ecc1eed386	waveshare213v2: Add support for partial drawing ... When the destination rectangle didn't start at (0,0) or cover the whole display the Dev.Draw function would continue to update the display in full. Obviously that didn't result in a good output. This change updates the drawing logic to only update the affected area (aligned to whole bytes on the horizontal axis) and limits the amount of transferred data to the minimum needed to cover the destination rectangle. The calculation of the various offsets as well as the function sending the image data are written to support unittesting. Signed-off-by: Michael Hanselmann <public@hansmi.ch>	4 years ago
