Scott Shawcroft	8d4296f964	Add board.DISPLAY to MagTag. Fix luma computation ... * 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.	2020-11-13 18:57:52 -08:00
