Fix luma computation 2020-11-14T02:57:52+00:00 Scott Shawcroft scott@tannewt.org 2020-11-11T02:02:16+00:00 urn:sha1:8d4296f96430795936a22769da35732e5342b25c * Initialize the EPaper display on the MagTag at start. * Tweak the display send to take a const buffer. * Correct Luma math * Multiply the blue component, not add. * Add all of the components together before dividing. This reduces the impact of truncated division. Add polarity and phase to FourWire. 2020-03-25T18:22:46+00:00 Scott Shawcroft scott@tannewt.org 2020-03-25T18:22:46+00:00 urn:sha1:6b7acc65b655dd203b08b2d53f08ad56c7da1041 It was fixed as 0/0 even though it used to get it from the current SPI state. This makes it more explicit with kwargs.
